Google sometimes lists URLs that it's not allowed to spider, because it's blocked by robots.txt, because a lot of links point to a URL. A good example of this is a search for [RTL Nieuws] (disclosure: RTL is a client of mine). rtlnieuws.nl 301 redirects to the news section of rtl.nl. But... rtlnieuws.nl/robots.txt exists... And has the following content:

User-agent: *
Disallow: /

Because of that, the links towards rtlnieuws.nl don't count toward the news section on rtl.nl, and Google displays rtlnieuws.nl in the search results. This is unwanted behavior that we're trying to fix but for now it's a good example of what I wanted to explain. By blocking /wp-admin/ and /trackback/ in your robots.txt, you're not preventing them from showing up.

Unfortunately, recently the /wp-admin/ block was added to WordPress core, because of this Trac ticket. In the discussion on that ticket, I've proposed another solution in this patch. This solution involves sending an X-Robots-Tag header, which is the HTTP header equivalent of a meta name="robots" tag. This would in fact remove all wp-admin directories from Google search results.

WordPress Robots.txt blocking Search results and Feeds

There are two other sections which are blocked in the suggested robots.txt, /*?, which blocks everything with a question mark and as such all search results, and */feed/, which blocks all feeds. The first is not a good idea because if someone were to link to your search results, you wouldn't benefit from those links.

A better solution would be to add a <meta name="robots" content="noindex, follow"> tag to those search results pages, as it would prevent the search results from rankings but would allow the link "juice" to flow through to the returned posts and pages. This is what my WordPress SEO plugin does as soon as you enable it. It also does this for wp-admin and login and registration pages.

I'm aware that that is different from Google's guidelines on this topic at the moment, which state:

Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines.

I've reached out to Google to get clarification on whether they would say my solution is acceptable as well, or perhaps even better :) .

Blocking /feed/ is a bad idea because an RSS feed is actually a valid sitemap for Google. Blocking it would prevent Google from using that to find new content on your site. So, my suggested robots.txt for WordPress is actually a lot smaller than the Codex one. I only have this:

User-Agent: *
Disallow: /wp-content/plugins/

I block the plugins directory because some plugin developers have the annoying habit of adding index.php files to their plugin directories that link back to their websites. For all other parts of WordPress, there are better solutions for blocking.

The other WordPress Robots.txt suggestions

The other sections of the robots.txt as suggested are a bit old and no longer needed. Digg mirror is something for us old guys who remember when Digg used to send loads of traffic, Googlebot Image and Media Partner are still there but if you only have the above in your robots.txt you don't need specific lines for them in your WordPress robots.txt file.

Gravity Forms + Custom Post Type addon

By default, Gravity Forms allows you to create posts through a form. It doesn't have support for custom post types at the moment though, in part because a wonderful plugin was already created that allows for this. This plugin, aptly named Gravity Forms + Custom Post Types can be downloaded from WordPress.org.

Once you have both Gravity Forms and this plugin activated, you can start creating a form. The first step is to make the form fill our custom post type. We start with creating a form and dragging in a title field:

The title field can be found in the posts field section of Gravity Forms field, below the advanced fields:

Once you've added this input field and given it a name, go to the advanced section of its edit block, you'll see an option to save as post type, this has been added by the afore mentioned plugin:

You check the box and select the custom post type you want to use, in my case, WPSEO Themes. Now we start adding the form. We need a couple of different types of values:

• The title: done.
• The "description", which will just be the body text, so you can easily drag in the Body input field.
• An image, which should be saved as the featured image too, more on that below.
• Several custom fields, more below too.

Adding a featured image trough the form

This is actually pretty easy: drag in an image field and click edit, you'll see something like the screen below:

As you can see, setting the image as featured image is as easy as ticking the box. It's wise to also ask for a description if you don't know what's going to be on the image. In my case, it's a screenshot of the theme, so I won't bother and just set the alt tag automatically.

Adding custom fields through Gravity Forms

The next step is to add the several custom fields we need. In my case I had 5, but you can have as much as you want. You start by dragging a Custom Field input into your form. Once you have that, you click edit and you select the appropriate custom field type:

In this case, I'm asking for the theme URL, so I select website, but there are all sorts of options you can choose from, as you can see. Now here comes the tricky part, you need to set the name of your custom field. You should go into your Types -> Custom Fields page and check the second value below the custom field title:

That's the name of your custom field, but you should prefix it with "wpcf-", because that's the Types plugin naming convention, which prevents its custom fields from clashing with other ones.

Of course, if you created a custom field group from already existing custom fields you don't need to prefix the custom field name.

True / false or "boolean" input fields

Some of your custom values might be checkboxes, they're either on or off, true or false. That's called a boolean value in math / developers language, but for you, it's really simple. Just create a custom field type "checkboxes", and go into it's settings:

Be sure to check the "enable values" box and set the value to just "1". That way, if checked, Gravity Forms will save it as value "1" and the Types plugin will "get it".

Deciding on workflow

Now, once you've used the above info to finish your form, you need to decide on a workflow. On the post title field, the one whose advanced settings we used to save this input as a custom post type, we now go to the "normal" properties:

As you can see, you can set a default post author and a post status. Now in my case the author will be me in most cases, as nobody will be logged in. However, if you have enabled registration on your site, you can force people to be logged in before even being able to use this form, by going into your forms advanced settings and checking the "require user to be logged in" checkbox:

This allows for all sorts of workflows, find one that suits your site!

Conclusion

We still haven't written a single line of code, yet we've already created a custom post type and created a form that allows people to submit custom post types to us.

So, one more thing to check of off the to-do list:

1. Creating a custom post type + custom fields.
2. Creating a form through which people can submit themes that fills this post type.
3. Creating a browsable interface for this post type.

In my next post, I'll explain how to use the Views plugin to create "views" for this post type and unveil the finished product!

Database of Themes that support my WordPress SEO plugin

I've also got a project I'll use this for: I want a database of themes that support my WordPress SEO plugin, with some specific settings info, a screenshot, etc. I want to store these as a custom post type. So the first step is to determine which info I would need to store:

• Basic stuff:
  • Title of the theme
  • Short description
  • Screenshot
  • URL
  • Is this a paid theme or not?
  • Price (if applicable)
• And some more advanced stuff:
  • Does this theme have its own SEO options that "yield" to WordPress SEO?
  • Does this theme support breadcrumbs?
  • Does this theme require force rewrite titles to be on or not?

Creating a Custom Post Type

Having determined what I wanted to store, the next step was to create a Custom Post Type. That's as easy as using this interface:

I could add Taxonomies to it as well, but I'll leave that for now, although creating a taxonomy is just as easy through the Types interface. I end up with my WordPress SEO theme CPT:

Adding Custom Fields

You'll think "huh, that hasn't got any of the specific data yet": that's right. It doesn't. That's where the true power of Types comes in, you can create "Custom Field Groups" and add these to post types. So I did:

As you can see you can choose from a lot of different types of fields, and all these types have their own content checks. For instance for a URL, it'll allow you to "force" a correct URL. I've added the custom field group to my WPSEO Themes post type, and now, when I go into edit or create a new WPSEO Theme "post", I get this interface below the title and content area:

So far, no coding was required, thanks to the wonderful Types plugin! You can get that, for free, on wp-types.com or on WordPress.org.

So, what we needed to do:

1. Creating a custom post type + custom fields.
2. Creating a form through which people can submit themes that fills this post type.
3. Creating a browsable interface for this post type.

Types WordPress plugin – Easy Custom Post Types is a post by Joost de Valk on Yoast - Tweaking Websites.A good WordPress blog needs good hosting, you don't want your blog to be slow, or, even worse, down, do you? Check out my thoughts on WordPress hosting!

When I added mine, in the beginning, it drove lots and lots of traffic. People weren't used to it yet and thought I had somehow "found my way into core". Recently, I've added more elaborate tracking to my WordPress SEO plugin links. Allowing me to see how much traffic the individual sections of my plugin were sending back to my site. Let me share that with you now (click for a larger version):

Traffic and conversion statistics for plugin links for the last 28 days

As you can see, the widget sends a bit of traffic (1800 visitors in total) but only drove 3 conversions... Conversions on my site are click outs on affiliate programs and, more importantly, sales for my website review service. Turns out, people clicking on from the plugin interface or the plugin link are far more valuable visitors than people clicking on the dashboard widget.

So, in an effort to annoy less people and focus on the traffic that matters, I've just pushed out version 1.1.5 of my WordPress SEO plugin, without the dashboard widget. I will shortly remove it from my Google Analytics plugin too. Of course other developers should do their own analysis if they want to, but for me it's clear that the widget doesn't help enough to be interesting.

If you used the dashboard widget regularly to find new posts on my site, please consider subscribing to my newsletter using the form below!

For those who do decide to yield and for those who do not integrate SEO functionality into their theme, this is the guide to follow on how to make sure your theme works with all the major SEO plugins and more in particular, my WordPress SEO plugin.

1. Basics
2. Head elements
   1. Titles
   2. Meta's
   3. Link items
3. Body elements
   1. Breadcrumbs
   2. Other body elements
4. Is your WordPress SEO plugin active?

Basics

Whether or not your theme is in the WordPress.org repository, you should strive to meet their Theme Review guidelines. With the theme check plugin you can simply check whether that's the case for most of the technical aspects. This makes sure you have all the necessary hooks for plugins to do their work. If any of those fail, fix them before even looking at the stuff below.

Head elements

Titles

The most common issue with SEO plugins and WordPress themes is with titles: theme authors have a tendency to hardcode (sections of) titles into their themes, which results in hard to fix behavior, which I recently discussed here and hasn't been fixed in WordPress core yet. In short, your title should be not even a tiny bit longer than this:

<title><?php wp_title(''); ?></title>

If you decide to embed SEO functionality in your theme, you should then put a filter function on to that wp_title functionality just like a plugin would. This allows you to "unhook" that filter when an SEO plugin is active.

Meta's

Meta tags come in a vast amount of shapes and sizes, but there are only a few that "matter". There are the meta description, the meta keywords (on which I have a strong opinion too) and the meta robots tag. In my opinion, your theme should never embed any of these meta tags, but, if you decide to embed SEO functionality into your theme, write functions for these things and hook them on to the wp_head action.

Be very, very sure to allow for site owners to fully disable any meta functionality you write. I regularly, read: daily, advise people to change themes when their theme has a lot of SEO stuff embedded that is just plain wrong or collides with other plugins. Make no mistake: a portion of your users, probably a large portion of your users, cares about their SEO. Getting it wrong is worse then not doing anything, so if I were a theme author I'd most definitely opt for the latter.

Link items

There are a lot of <link> items that matter for SEO these days. There are rel=canonical, rel=next and rel=prev and a few more. WordPress does rel=canonical on single posts and pages but nowhere else yet, though a patch for core is ready to make WordPress add rel=canonical in more cases, but your theme should not do any of these. You're, to be honest, bound to get them wrong.

If you do decide to add them, do it in the same fashion as meta elements: hook them on to wp_head and make sure site owners can disable the functionality.

Body elements

Breadcrumbs

While the above points make integration for any SEO plugin easier, this point is more specific for my own WordPress SEO plugin. Integration of my breadcrumbs is quite easy, use something like the following code:

if ( function_exists('yoast_breadcrumb') ) {
   yoast_breadcrumb('<div id="breadcrumbs">','</div>');
}

This code will not display anything unless the breadcrumbs feature of my SEO plugin is enabled.

Breadcrumbs Variables

This breadcrumb path takes the following 3 variables:

$prefix
The code that your breadcrumb should be prefixed with. Default to an empty string.

$suffix
The code that should be added on the back of your breadcrumb. Default to an empty string.

$display
If set to false, will return the breadcrumb path instead of echo-ing it. Defaults to true.

Other body elements

You should take note of my guides on HTML heading structure and HTML Sitemaps. While my SEO plugin doesn't "interfere" with those, it's good practice to make them optimal. You should also read my WordPress SEO Theme Guidelines to make sure you're doing all the other necessary things.

Is your WordPress SEO plugin active?

You should check whether a constant named WPSEO_VERSION is defined, preferably like this:

if ( defined('WPSEO_VERSION') ) {
// Disable your SEO stuff
}

It includes a new tool built by yours truly to help you create the necessary redirects. Keep on reading!

Why change your WordPress permalink structure?

Most of the time I tell people to change their WordPress permalink structure, it's to get rid of the dates in their permalink structure. If their content is "timeless", it just shouldn't be there. In my opinion, the only type of site that should have dates in their permalink structure is a news site. All other sites should strive to write content that is "timeless".

Having a date in your permalink structure has proven to diminish the CTR from the search results for older posts. People are just not likely to click on a result that's two years old, even though it might very well be that your post has the answer they seek. With Google seeming to use that CTR more and more as a (very valid) ranking signal, that's becoming a more serious factor each day. I did a long post on WordPress SEO URL / Permalink considerations a while back, you might want to (re-)read that.

Performance considerations

Up until WordPress 3.3, there was / is indeed a quite serious performance issue when you have a lot of pages when you use just /%postname%/, luckily, that is solved in WordPress 3.3. I have debated people quite a bit saying that it's easily solved with some caching but having it fixed in core is a big step ahead, so there are no more excuses to not use /%postname%/.

Changing WordPress Permalink Structure

There are two steps in changing your WordPress permalink structure. The first is simple, go to Settings -> Permalinks and select Post name:

Change your WordPress Permalink Settings

If you don't have the post name option yet, you're not on WordPress 3.3, the release of which is imminent. You could wait a bit for the update, or you could just add /%postname%/ as a custom permalink structure.

The second step is to redirect your old permalinks to your new ones. To do that, you have to add redirects to your .htaccess file, I have created a little tool that generates these redirects for you based on your domain and your old permalink structure. To use this tool, click the button:

Generate Redirects

There you have it! If you copied the redirect into your .htaccess, you should test whether it's working. If it's not, chances are you're not allowed to use RedirectMatch, which makes changing your WordPress Permalink Structure a bit harder and not something I can easily cover in this post.

Let me know whether the tool works for you and what you've done to your permalinks!

After a couple of years of struggling with email I have finally found the solution to make sure each of my emails reaches the inbox of its recipient and I'm about to share it with you.

Note: this is not a paid review. In fact, since Postmark doesn't have an affiliate program, it's not even a post with some affiliate links. It's just me solving a problem for myself that I hope you will now be able to solve too.

The problem: email not reaching its recipient

I wrote about email reliability before, but let's be honest: getting all the web servers we use for sites to send email reliably is a pain. You need to setup SPF records, preferably set up DKIM too and make sure that your web servers do not get blacklisted. One of my servers, for which I had set up SPF, for some stupid reason got blacklisted a couple of weeks ago, resulting in a couple of website review emails not reaching my customers. I hated that so much that I started looking for another solution.

On this site, I had switched from Gravity Forms to Wufoo a while back. Wufoo is another awesome web forms service, with the at that time "added value" that Wufoo would take care of the email sending for me. My main gripe with using Wufoo was that I really wanted my forms and the entries of my forms in my site's install, not somewhere else. On top of that, Gravity Forms gives me a bit more programming flexibility, so I wanted it back. So, I had two email problems and started to look for a solution to both at the same time.

Postmark: reliable email

I found that solution in Postmark, which handles transactional email through a set of reasonably simple but reliable API's. Using this pre-built library, I was able to replace the email sending in my website review application for Postmark within about 10 minutes.

Yes, Postmark costs a bit of money, but if you consider that at $1,50 per thousand emails, you run a lot smaller chance of losing customers over email not reaching its destination, it seems to me that that's money well-spent.

It took me a bit longer to code a WordPress plugin that I liked for Postmark. There are a couple of WordPress plugins listed on the Postmark site, but all of them relied on CURL, which I don't have on every server I run WordPress on, and they all ignored some of the headers that plugins like Gravity Forms passed along. So I used the same pre-built library, but adapted it this time to use the WordPress HTTP libraries and added a wrapper to more reliably pick up all the headers that might get added by plugins.

The result is a plugin that is pretty easy to use, my own Postmark Email for WordPress Plugin.

WordPress email sending tips

By default, WordPress sends email from wordpress@example.com, where example.com is your domain. In 99% of cases this is a non-existing email address. More and more people, including Postmark, are saying that using a non-existent email to send your email from is not a good idea. I agree. So I created wordpress@yoast.com, which gets filtered into a tag in my email.

The great thing about actually creating that email address is that you can also assign a gravatar to it. This means that when people use email clients like Sparrow, or other email clients that support Gravatar, they'll see a nice avatar image for your email too. In my case, I made sure that image was the Yoast logo.

Go forth and email!

And please do let me know your comments about both Postmark, the plugin and your tips for reliable email in the comments!

• If I have just made changes to my WP site, does it help to toggle the cache plugin?

  Absolutely. My SEO plugin force refreshes the cache because otherwise people start emailing me that stuff doesn't work when it works perfectly. On sites with more traffic though, you could also just leave the cache as is and wait it out a bit.

• How do I move a WordPress site, changing its permalinks but keeping the social numbers counts (post tweets/likes/shares)?

  The answer to this is an unfortunate but resounding: you don't. I've written a tutorial on moving WordPress to a new domain quite a while ago, but you simply can't keep those stats. All the more reason to think long and hard about moving domains...

• My buddy Richard thought he was funny, and asked: How much wood could a woodchuck chuck if a wouldchuck could chuck wood?

  The answer is simple, of course: a woodchuck would chuck as much wood as a woodchuck could chuck if a woodchuck could chuck wood.

• Will you be focusing on wordpress for the rest of your life? If not what do you think will be the reason why you change your focus?

  I might be smart, but I'm no sightseer. Also, while I work with WordPress a lot, a lot of my time is also spent on consulting and website reviews (which we do for all sorts of sites).

• What is the best practice to SEO a WordPress.com site? Is it even possible?

  Of course there are things you could do on a WordPress.com site, some themes there are better than others and you can do a whole lot content wise. The minute you start asking questions like that though, you should really consider getting a self-hosted WordPress.org install and taking control of your own destiny. You'll reach a point where you'll want to do more and WordPress.com doesn't allow you to do that and the longer you wait, the harder it is to move, so, move now.

• When do you think that WordPress is going to completely rewrite their code base so it's an actual CMS instead of a hacked together glorified blogging system?

  I find I get that question quite a lot and it annoys me. WordPress is being rewritten all the time. Check out the development that happens on Trac. Most of the people who ask questions like that haven't had a decent look at the codebase for ages. WordPress IS way more than a glorified blogging system already and if there are specific issues you have with the way it's coded, patches are welcome!

• If you start working on a WordPress blog for a client and there are no plugins installed, which ones do you always install?

  A couple: my own WordPress SEO & Google Analytics plugins, W3 Total Cache and usually Gravity Forms. Of course each site is different so there'll be more plugins after that depending on that site's and site owners needs and wants.

• What do you think has more value? A good domain name or good link building?

  Good link building, any day, every day. You see, domain names, especially so called "exact match domain names" are bound to be devalued at some point. Good link building will always create traffic to your site, just from those links alone, so that's always worth while. Those links also bring in rankings but in really good link building, that's often just a side effect. I recently talked about Eric Ward's mailing list, you should check out that post.

• Your SEO plugin places a canonical tag on every generated page and I have an ongoing argument with a co-worker about that. He says that this tag should only be on pages that contain duplicate content and that it is intended to 'tell' the searchbot where to look for the original content. Googling around doesn't clarify a lot. Could you please tell your reasons behind placing it on every page?

  I get this discussion a lot. The thing is, if I was 100% sure that a URL could only be accessed through that specific URL with no query parameters added, I might not add a canonical. There's nothing against it, but it'd just be a bit cleaner. However, these URLs:

  http://www.example.com/

  http://www.example.com/?campaign=email

  Are essentially the same for a WordPress install in 99% of the cases. However, they're not the same for Google and other search engines. So, if I wouldn't add canonical, the link value of the second URL would be waisted and, in fact, you'd have a competing duplicate content URL in the search results. That's why I add it to all pages.

• I noticed you don't use a comment system like disqus or intense debate. Would be nice to hear your thoughts about whether we should or should not use a comment system in WordPress.

  If I were to use a comment system, I'd use Facebook comments. The benefits of that and the fact that it gets way less spam are quite high. So far I've decided not to do that yet because a couple of my regular visitors and active commenters actually don't have Facebook accounts. Also, my comment redirect plugin doesn't work with those systems, which I think is a pity.

  I'll say one thing: the amount of work I have to do to keep this blog spam free is nothing short of ridiculous. Read this post to see what I mean.

That's it, what do you think, should I do this more often?

Last friday I was telling my buddy Remkus de Vries, known as @DeFries on Twitter, that I was almost done with the internationalization support for my WordPress SEO plugin. He told me that I should be using GlotPress, which is a collaborative, web-based software translation tool maintained by some of the people behind WordPress. I concurred and asked him to set it up for me.

He did and he wrote a post about it: How to use GlotPress for your translations. After a bit of work on my side on getting a registration form going, I tweeted about my GlotPress being there on translate.yoast.com. Within 20 minutes about 10 people had registered and started translating. I was very excited about that and decided to look into it a bit better by the following morning, when 14 people in total had signed up already.

Because I could see this becoming unmanageable quite soon, I decided to create a mailing list for the contributors. As you'll see when you've read Remkus' post I listed above, we use a WordPress install on /register/ to manager the users. This allows me to use Gravity Forms, along with its User Registration add-on, to allow people to register. Because I built it that way, it was a piece of cake to add the Mailchimp add-on and make sure all new translator were connected to the mailing list as well.

Be sure that when you set it up like this too, you make the language people want to translate into a variable in MailChimp too, so later on you can easily segment on that, by emailing just the people who are translating your plugin(s) into Polish, for instance.

The amount of people working on this has surprised me. I've tweeted about it twice and so far, 31 people have signed up and are actively translating into 12 different languages, so far translating 2568 sentences!

Your turn?

Are you using WordPress in your native language? Would you want to contribute some of your time to help translate my plugins into your native language? Then register here, you'll receive instructions from there. If your language isn't listed yet, please allow me some time to enable that language and from then on your good to go, looking forward to seeing my plugins run in more languages then were speaking on the tower of Babel!

Today is also one of those days of the year again where I ask you, my dear reader, whether you're a lurker or not, to help me out. I've got three things that need some attention and I hope that one or two of them are applicable to you and you're willing to help me.

First of all, I'm soliciting testimonials for two of my plugins, I'd like you to tell me why you use them and how much you like them (if you like them, that is). So, if you please could:

• Leave a testimonial for my WordPress SEO plugin
• Leave a testimonial for my Google Analytics plugin

Next, if you hadn't noticed my previous post, I'm looking for (premium) themes and theme frameworks that work with my WordPress SEO plugin and for themes that are giving issues. This allows me to both compile a list of themes that work well with my WordPress SEO plugin as to reach out to theme developers and see if we can work together to get things fixed. So, if you use a theme that you didn't build yourself but that you either bought or downloaded from WordPress.org, please fill out this survey.

Now, I've been with VPS.net for quite some time, from their very beginning in fact, and I've always liked the service and the people working there. I'm not one to easily leave and on top of that, having had issues at other hosting companies before, I know that things are bound to go wrong at some point. So, I decided to confront my contacts at VPS.net and "talk to the boss". That boss is someone I hadn't spoken to before, Rus Foster. Rus has recently (7 weeks ago) joined VPS.net as their new Managing Director, although he's been in the VPS business for years, replacing Nick Nelson, who's gone higher up in the UK2 Group.

As you can see, I asked him some, I think, rather tough questions. I was happy with the answers I got, and must say that the changes he's talking about below on the AMS cloud have indeed had a very positive effect on my yoast.nl server.

Interview with Rus Foster, MD of VPS.net

Hi Rus, thanks for agreeing to this interview. My goal is to shed some light on what is currently causing all the issues around VPS.net. First of all, it seems as though every day, somewhere in the world, a VPS.net SAN dies. Some locations have more issues than others, but in general, it's been quite bad lately. What's causing that? And, more importantly, what will you do about it?

Start with the easy questions eh? Nothing like whats your favourite colour? :)

Seriously though yes there have been SAN issues on some of our newer clouds.

Some of the SANS in multiple locations have been showing instability issues caused by the software running on them. As such we are starting to undertake a very aggressive upgrade schedule to move the SAN software to the latest version. Coupled with this we are also upgrading the storage network within each cloud to increase I/O speeds.

We are however also looking to start using the enterprise class Nexenta storage solution on our new clouds which is engineered fundamentally different to our current SAN solutions. The upshot of this is that the system is much more resilient to failure meaning in the event of a failure there will be no noticeable effect on customers.

This will be going live on our next cloud but more about that later .....

When you say "very aggressive upgrade schedule", what do you mean, exactly?

We have identified 6 clouds where we feel significant upgrades, or full migrations to new facilities are required. We are doing 1-2 clouds a week and aim to have everything completed within the next 6 weeks, if not sooner. This is a significant investment in our infrastructure to increase resiliency and performance.

To be fair, some people would say that it's a significant investment to make it work the way it should... Which clouds are we talking about?

There were decisions made in the past that were right at the time. Those choices however no longer reflect customers expectations as cloud hosting is becoming more mainstream. We are making decisions now that prepare us for the future allowing easier service enhancements to be rolled out to all our customers new and old. We are targeting clouds in both the US and Europe. Some of the work, for example on our Amsterdam cloud, has been completed.

Could you say that maybe you've grown a bit too fast? (Which would be partly my fault, perhaps, sorry about that)

We learn from mistakes. There is nothing wrong with growing fast. There is something wrong with not managing that growth. I would say that is where as a company we found ourselves tripping over our own feet. My personal focus is split into both pushing the growth of the company, looking at exciting new markets and technologies but also its vitally important that we look after our current customers. This is reflected in us bringing back such old favourites as sales live chat but also focussing on how we can help existing customers. This include things such as the cloud upgrades as well as some exciting upgrades we have coming for all customers.

Apart from the SANs, another issue seems to have been the fact that you weren't responding during those outages, either on tickets, or on Twitter, with the status blog being deafeningly silent too. What are you going to do about that?

Communications. Communications. Communications. Nothing travels as fast as bad news. We need to be quicker. We need to be more open. We are taking steps to do that. We are now proactively emailing customers in the event of an outage. We are making it the sole responsibility for the manager on duty to communicate with customers. The status blog and twitter are important fields of communication but they can't give customised responses to each customers. Our support ticket system is in place for that.

I've seen you jump in on more and more tickets yourself, are you one of those managers on duty?

Its best to lead by example. I never ask anyone to do something that I wouldn't be willing to do myself. When things get busy in an outage its really a matter of needing all hands to the pumps. Thats why you will see me replying to all sorts of support tickets from simple reboots to full implementations of load balancing.

I get the feeling, talking to some of the people who bought a VPS, that they actually shouldn't have a VPS. They have two types of downtime, the one caused by themselves as they don't really know their way around a web server, and the ones caused by SANs or other hardware failures at VPS.net. I think that for people who have a lot of those first issues, the new Cloud Hosting, or a somewhat faster WestHost package, both a bit more managed, would be better for them.

Do you agree? If people think that's true for them, is there any way for you to help in that?

We all love power. As a petrol head I dream of having a TVR Sagaris on the drive but do I need the power? Of course not. Some people do however need that power. It's all about what matches your individual needs. If people just have a few websites that need to "just work" then a VPS isn't always the best choice and there are other things in our current, and upcoming, product range that could suit them better. If however people do require large amounts of customisation VPS are still a good way to go. If they do require that little bit of hand holding they can always get an On-Demand ticket for a one time issue or pop management on top for unlimited help.

If a customer wants to move to another product we can move a reasonable number of sites free of charge.

Cool.

So you mentioned a new cloud... Tell me more.

Yes our Japan cloud is the first cloud to be running our new Nexenta storage system and OnApp 2.2. It will also be live next week. Coupled with this, as we know people might be a bit wary of the new solution, we are doing first month, free of charge, for customers new and old. There is a limit of 10 free nodes per customer.

What can customers do if they think they deserve more attention?
They can contact me directly at rghf@vps.net.

VPS.net issues: what’s up and what will they do about it? is a post by Joost de Valk on Yoast - Tweaking Websites.A good WordPress blog needs good hosting, you don't want your blog to be slow, or, even worse, down, do you? Check out my thoughts on WordPress hosting!

Now I bring this up for a single reason: the title is the single most important piece of content on a page relating to SEO. In the most recent update of SEOmoz's ranking factors, the presence of a keyword in the title was agreed by SEO's to have an "influence value" of 94.4 out of 100. That's huge.

In WordPress' most recent default theme, dubbed Twenty Eleven, the content of that title tag is determined by the following code:

<title><?php
/*
 * Print the <title> tag based on what is being viewed.
 */
global $page, $paged;

wp_title( '|', true, 'right' );

// Add the blog name.
bloginfo( 'name' );

// Add the blog description for the home/front page.
$site_description = get_bloginfo( 'description', 'display' );
if ( $site_description && ( is_home() || is_front_page() ) )
	echo " | $site_description";

// Add a page number if necessary:
if ( $paged >= 2 || $page >= 2 )
	echo ' | ' . sprintf( __( 'Page %s', 'twentyeleven' ), max( $paged, $page ) );

?></title>

With all due respect, I hate that. The reason I hate that is that it means that on the front page of your site, no matter what you do, your title will always be of this format:

NAME OF SITE | DESCRIPTION OF SITE

On other pages, it will be:

NAME OF ARTICLE | NAME OF SITE

So we effectively hardcode in our design templates the way we output one of our most important bits of content on a page. That's very far from the separation of design & content that the web community at large has been striving for over the last few decades.

If you're now thinking, "hey, I'm using that theme and I have another page title for my homepage", you might be right, I'll get to that. The reason you're able to do that is also the reason why I regularly get questions about my WordPress SEO plugin and theme X, Y or Z having issues with the title.

The bad solution: Output Buffering the page title

I don't want to spend this entire article explaining what output buffering is, so if you don't know, this is a rather simple explanation. This process is used by most big SEO plugins. What they do is: catch the output of a page, look for the <title>, fix the contents of that title, return the output. For the record: if you check the "Force rewrite titles" box on the Titles page of my SEO plugin, it does just that. The reason my plugin has had issues with titles is exactly that: I don't have that box checked by default.

Now one can argue over whether output buffering in general is a bad idea or not, the way it's done here is arguably bad, although the only current working solution. It uses way more resources than should be needed to change the title and, possibly worse, it effectively disallows other plugins that don't do the buffering to have an influence on the title. On top of that, in my testing, on most servers it adds about 0.5 seconds to the page load time.

The good solution: something new in core

For quite a while, I thought that changing the way we, as a community, use wp_title would be a fix to this. I no longer think that it is. The reason for that is that it would create all sorts of other issues, with themes and plugins alike. In fact, Andrew Nacin already tried to do that a while back, see this changeset, and reverted the changeset because the output buffering plugins broke because of it. I think we need a new function, specifically aimed at displaying the page title. Ideally this function would hook into wp_head and would be using the theme_supports functionality.

I've been working with Andrew on a patch, which has been heavily discussed on this Trac ticket. I have good hopes that something along these lines will go into core, but would love to know your opinion.

Discuss: The Page Title in WordPress Themes is a post by Joost de Valk on Yoast - Tweaking Websites.A good WordPress blog needs good hosting, you don't want your blog to be slow, or, even worse, down, do you? Check out my thoughts on WordPress hosting!

I run a couple of WordPress instances on this server. This website, which you're looking at, but also a MultiSite install in /bugs/, running WooThemes' FaultPress. Now had I been paying attention, I would have read this post on the WooThemes blog a month ago, telling me to upgrade their WooFramework to fix vulnerabilities. I didn't, I was slacking. This morning I found out that was stupid, as that exact vulnerability was used to hack my server.

The issue is bigger though: so many of you don't upgrade regularly. You see, security breaches happen. I have helped quite a few plugin authors fix security issues in their plugins, and I myself have been helped by the likes of Jon Cave and Andrew Nacin to fix security issues in my own plugins. When I update a plugin though, it's very rare to see more than 20% of the users update within a week. We, as a community, need to get better at that.

Now, I'm on both sides of this fence, I'm a user and a developer. As a developer, I started thinking about how I could get more of you to upgrade. I know Genesis has a feature in their backend that's quite cool:

You just drop your email in there and you get an email when an update is available. I'm going to add something like that to my own bigger plugins, though I have to think a bit about what the best way to do this is...

The moral of this story is quite simple though: don't let this happen to you: upgrade your core, themes & plugins very regularly!

I was talking about this with Terry Myers of VPS.net, and decided to turn it into an interview, so here we go:

• Terry, could you introduce yourself to the readers of Yoast.com and tell us what your role at VPS.net is? 

  Thanks for giving me the opportunity to chat with you and your readers today. I'm Terry Myers, the Chief Evangelist for VPS.net. I've been working with the company for a little over the past year, working in a couple of different roles. The great thing about my role with the company is there isn't a real set job description, so I find myself going wherever the customer needs me. My day to day tasks range from chatting with our customers on Twitter, where you can follow us @vpsnet, to working with our engineers to setup a complex multi-server cluster for our customers. Both of which, are oddly enough, equally as exciting to me. I'm guess I'm a bit of a social nerd.

• What is the difference between Cloud Hosting and a VPS Cloud Server, which would you advice to whom? 

  Our cloud hosting is a product we recently launched in May of 2011. When doing market research we found that there was a lot of demand for an easily administrated cloud hosting solution. What we've done with our cloud hosting product is essentially created a shared hosting product that you would get from any web hosting company, and then combined that with our cloud infrastructure. What you get is a shared hosting account that is built off of the cloud, which means it's easily scalable, while also having extremely good redundancy, as there are multiple servers available for your site to run on.What makes this different from our cloud servers, is the cloud servers require a bit more technical skill, requiring you to administrate the web server. Our cloud servers are like a private web server for your specific website. Where they're advantageous over the cloud hosting is they have a bit more flexibility, in that you can configure the server in fashion you need, while also being able to handle more traffic.
  Between the two products, I really feel that we have a solution for almost any customer. If you're running just a basic website, our cloud hosting will likely work out tremendously well for you. If you have a site that requires a unique setup, or a site that receives a significant amount of traffic, then our cloud servers can suit your site well.

• WestHost is a sister company to VPS.net, what's the difference between WestHost WordPress Hosting and Cloud Hosting? 

  The WestHost WordPress hosting solution is a great product. It lets the customer get up and running with a wordpress installation in just a few minutes, and that works out very well for a lot of people. The difference between the two products is with the infrastructure used on the backend. The WestHost WordPress hosting uses dedicated servers that are shared amongst multiple customers, like any traditional shared hosting arrangement. It's a solution that makes for a stable, and affordable hosting experience.Where our product is a little bit different is that instead of using dedicated servers to host our clients, we use our cloud infrastructure. We're essentially able to create servers on the cloud to host our cloud hosting clients, which benefit from the instant scalability the cloud offers, along with the auto-failover abilities. What this means for our clients is if one client is put on a site like Digg.com, we're able to immediately add resources that'll prevent their site from going down. Additionally, if one server in the cloud experiences a problem, like a hardware failure, that has no effect on the clients. The other servers in the cloud just take over the work that it was doing.

• Especially in WordPress hosting, there seems to have been a race to the bottom in prices. Slowly people seem to realize that if you pay peanuts, you get monkeys, yet they'd like to know what kind of support they can expect if they pay a bit more, after all $20 a month still doesn't allow you to have a dedicated engineer. What's VPS.net's service like? 

  We've definitely seen a shift in the market; people no longer are looking for the absolute lowest price, instead they've started to look at what their hosting company can offer them, and support is definitely a big part of that. We have a team of support engineers that are solely focused on our cloud hosting product. We're seeing average response times under 15 minutes, with the issue being resolved by the 3rd response, and on average, in less than 1 hour.

• That's actually quite impressive! Thanks for your time Terry, I'm quite sure my readers will know where to find you if they run into issues with their new Cloud Hosting accounts!

  Thanks. I'll definitely be around on Twitter.

Mashable has been running WordPress SEO for quite a while now and so have my friends over at The Next Web. Boris Veldhuijzen van Zanten, one of the founders and owners of The Next Web, recently said the following about my plugin:

“The SEO plugin by Yoast helps all our editors add SEO juice to their post fast & easy. Editors should focus on writing content, not gaming results. But they are the ones most suitable to write descriptions and titles for their own stories. The plug-in allows them to do just that without needing an SEO expert to walk them through the process. An invaluable tool for any professional blog."

I think Boris got exactly what my aim is with this plugin. I don't want to bore you with all the details, I want you to write better content and aid you with that. The help from Linkdex and the Page Analysis functionality we created in that has been invaluable. That said, I'm not there yet. The plugin still has a gazillion settings that you need to find your way through and I'm not happy with that. Functionality to fix that will be coming soon.

Another big big thanks is due for the guys at Level Level who designed the logo for this plugin as you see above, in the same style as the logo for my Google Analytics plugin. Guys: you rock!

Google News Module

Today I also finished the work on the Google News SEO Module, the first official module for my WP SEO plugin. It's free, if you're in Google News you should really start using it right now!

Update & Donate

So, it's there. If you were already running the plugin, update to 1.0, if not, install it now, have fun and tell me in the comments both why you use the plugin and what you'd like to see next! If you want to thank me, a donation is sincerely appreciated. All of the money that comes in in donations is spent on hiring the best WordPress developers for hire to help me improve on this plugin even quicker.

A good example of that is that I hired Jon Cave, a WP Core Contributor, to build the XML Sitemaps API that allows this plugin to easily create XML sitemaps for the very large blogs it's used on.

There's a whole ordeal in the WordPress community right now over the fact that WooThemes has decided to fork JigoShop into WooCommerce. Quite a few people have asked me for my opinion on this, given my recent trials and tribulations with copyright issues. I decided it would be good to give my opinion here instead of in tweets that can be misunderstood or taken out of context.

Let me start with a big fat disclaimer. I'm currently working with the WP e-Commerce team on several things, I like their plugin a lot and am thus bound to be a bit biased in this whole field.

Now: what WooThemes did was entirely within their right. The fact that they also hired two of the developers behind JigoShop may make it look a bit weird, but these guys were apparently freelancers before, not contractually bound to JigoWatt apparently employed by Jigowatt, the company behind JigoShop. In their response, JigoWatt have said that WooThemes, who tried to acquire them "grossly undervalued the business and didn’t come close to covering our initial development costs". You know what, while that sucks for them, that's how open source works, grows and prospers. Making an offer to buy is a gesture of good will, as there's no need, as shown by the next steps taken by Woo.

Right now we have two essentially the same plugins out there, though my guess is they'll quite soon be very different, making the landscape of WordPress e-Commerce plugins even more competitive. Both plugins will probably continue to be around and, I hope for both of them, successful.

It teaches us, as a community, something entirely different though, or at least I hope it does. It teaches us how important reputation and branding is. You see, the value of the plugin rises, because Woo decides to attach its brand to it. While I do not necessarily think that "Woo" is a seal of quality, some of their stuff is great, some of their stuff is not so great, they do have a well established brand and support environment.

The "Jigo" brand, on the other hand, is new. Nobody knows of it or about it. If I had to choose right now, between installing WooCommerce and JigoShop, I'd go for WooCommerce, every time, since they have a reputation to defend.¹

Now, as for that reputation: would I have decided to take the route that the Woo theme has decided to take? I can understand they tried to acquire JigoShop, given their issues with developing an e-Commerce plugin in-house. When that failed though, I think it'd been wiser for them to take a step back and re-evaluate. The backlash they receive now might do some serious damage to their brand, although to their credit they've been handling it wisely, honestly and open so far. Still, would I have done as they did? No. Do I think less of them for doing it? No.

You see, on the other hand, if Woo get through this episode well, they'll have a very valuable addition to their product offering as well as two pretty good new coders... Time will tell. For now, I wish both teams wisdom and success. Competition in a marketplace usually leads to better products for the end user, let's together make sure that is the case now as well!

¹ Luckily though, WP e-Commerce has been around for ages, they've shown that they actually understand e-Commerce quite well and are, in my opinion, the far better choice.

Update August 23rd, 2011: Google has made a simpler version available to those of you who are not able to follow the instructions below. It is still recommended that you do in fact follow the instructions below if you have the appropriate access to the blog you're trying to do this on, if not, please follow the instructions I added at the bottom of this post. I also updated screenshots and added two video's with explanations. Let me know if you have more questions in the comments, I've updated the date of this post so it will pop up again in your reader.

I did see some more examples pop up, for example, when I searched for [highlighting authors], both this post from Matt Cutts (on highlighting authors in the comments) and this post from Gina Trapani got an author highlight.

1. Is the link to the Google Profile from the author page required?
2. How to add rel="author" to a link in your menu
3. How to allow authors to add rel="me" to links in their bio's
4. How to allow authors to set their Google Profile URL
5. How to change the author URL
6. Update: the simpler version
7. Last (but important!) step
8. rel="author" + rel="me" actually works!

Is the link to the Google Profile from the author page required?

Apparently, yes, it is. It's quite logical for Google to want a link from your Google profile to your author page, it makes 100% sure that you are indeed the author of that piece of content when you link to your Google Profile and back from your Google Profile to your author page. Of course the link to your Google Profile wouldn't be 100% needed for this, I don't know whether Google will keep this requirement.

The flow should thus be as follows: article links to author page on the same domain. The author page on the same domain links to the Google Profile. The Google profile, in turn, links back to the author page.

So you are not, as some people suggested, meant to link to your Google Profile straight from the article, instead, you should link to your author page on the domain you published the article at and that page in turn should link to your Google Profile and be linked from your Google Profile.

How to add rel="author" to a link in your menu

One of the issues that came up with is that some people don't want to show the author on each and every post when the author on that blog is always one single person. Those people will usually have an "about" page linked in their site's main navigation, for instance, Robert Scoble, on his blog Scobleizer:

That "about" link could very easily be used to identify him as the author of each and every post, to Google, if it had rel="author" sticked to it. Turns out that this is actually very easy to do if you use the WordPress menu editor.

Go to the Menus page and in the top right, click on screen options:

Once you click that link, it'll fold out, and the display options will show, including "Link Relationship (XFN)", be sure to check that box:

Once that box is checked, you can edit your menu item to include the link relationshop "author" which will cause it to get rel="author" added to it:

Be sure to just add "author" (without the quotes) this is enough to make sure the link will have rel="author" added to it.

How to allow authors to add rel="me" to links in their bio's

If you update your bio on a WordPress blog you write on to contain a link to your Google Profile and want to add rel="me", you'll come to the conclusion that WordPress strips out all the rel elements from links. Why it does that is beyond me, I've already opened a Trac ticket and created a patch to allow it. Until that is in core though (if it makes it in), you'll need to allow it yourself. To do that, simply add this to your site's functions.php file or functionality plugin:

function yoast_allow_rel() {
	global $allowedtags;
	$allowedtags['a']['rel'] = array ();
}
add_action( 'wp_loaded', 'yoast_allow_rel' );

This will allow all rel values to be used, nofollow as well. You could tighten this more but I doubt you'll need it.

How to allow authors to set their Google Profile URL

If you don't want authors to add the link to their bio but would rather give them an input field to enter their Google Profile URL, you'll need to hook into the contact methods functions of WordPress. First, tell WordPress you want to add the Google Profile contact method:

function yoast_add_google_profile( $contactmethods ) {
	// Add Google Profiles
	$contactmethods['google_profile'] = 'Google Profile URL';
	return $contactmethods;
}
add_filter( 'user_contactmethods', 'yoast_add_google_profile', 10, 1);

This will add an input field on their edit profile page below the default AIM, Yahoo and Google Talk / Jabber contact methods:

Second, in your theme's author.php file, the author template, you need to add a bit of code to output this new URL:

$google_profile = get_the_author_meta( 'google_profile' );
if ( $google_profile ) {
	echo '<a href="' . esc_url($google_profile) . '" rel="me">Google Profile</a>';
}

Of course you can style this in any way you want, show it in a list, etc. Here on yoast.com, for instance, I replaced the default contactmethods with Facebook, Twitter and the Google Profile.

How to change the author URL

If for one or more authors on your blog you want to change their default author URL, you could do something like this:

function yoast_change_author_link( $link, $author_id, $author ) {
  if ( 'admin' == $author )
    return 'http://example.com/about-me/';
  return $link;
}
add_filter( 'author_link', 'yoast_change_author_link', 10, 3 );

This would change the author URL for the author with username "admin" to http://example.com/about-me/, you should of course change this to what you need in your specific case. This should work with most themes, if it doesn't with your theme, let me know what theme you're using and I'll try to come up with a solution.

How can I test whether my rel="author" implementation works

Once you've added one of this bits above, you probably want to test whether it's working. To do that, use Google's Rich Snippets testing tool. You can find an example report showing that my implementation is correct here. See the screenshot:

Now don't forget to take the last step, keep on reading below the simple version!!

An explanation video from Google

After this post Google's Matt Cutts and Othar Hansson did a video on the topic, feel free to watch it here:

Update: the simpler version

Because not everyone either has the technical knowledge and/or the actual access to their sites to be able to accomplish the above, Google has made a simpler alternative. I don't know whether this alternative will work forever, it does work now though. It's quite simple, just follow these steps:

1. Find your Google Profile URL, copy paste it.
2. Create a link with that profile URL, and add this ?rel=author to the end of the URL.
3. As an anchor text, use your full name with a +, in my case the anchor text would be: +Joost de Valk
4. Go to the last step, below the video embedded below.

The full HTML of my profile link would look like this (line break just to make it easier to read, you shouldn't have that):

<a href="https://plus.google.com/115369062315673853712
/about?rel=author">+Joost de Valk</a>

Of course, there's a video explaining this version too:

Last (but important!) step

Whichever version of the code you used, be sure to submit your details through this form. You probably won't get an email back but at some point it (might) suddenly start working!

rel="author" + rel="me" actually works!

To show that the markup above works (I use the complete version, not the simple version):

rel=”author” and rel=”me” in WP and other platforms is a post by Joost de Valk on Yoast - Tweaking Websites.A good WordPress blog needs good hosting, you don't want your blog to be slow, or, even worse, down, do you? Check out my thoughts on WordPress hosting!

For instance, if I search for Danny Sullivan's blog "daggle", the results now look like this:

This potentially has some nice side effects and I'm very curious how this will pan out. If they're going to show this in normal search results next to blog posts, which they say in their post that they will, more credible authors will get more clicks, independent of whether they rank better. This in turn allows Google to create a sort of "author trust rank". You see, when they show a picture of you next to your blog and you get more clicks than they'd expect because of that, you obviously have a higher credibility.

If it all works out like that, this might just be the last step some of those web journalists out there need to finally be able to demand the rockstar salaries they deserve!

I want those author highlights too!

To do this, you need to apply the authorship markup Google announced a couple weeks back. This basically means adding rel="author" to a link to the authors page on the same domain. My author link for this post, for instance, looks like this:

<a rel="author" href="http://yoast.com/author/admin/"
  title="Posts by Joost de Valk">Joost de Valk</a>

This code is generated by the WordPress core function the_author_posts_link(). When Google announced the authorship markup, I immediately created a trac ticket and patch for WordPress core to add rel="author" to both that function, and to all the places in both TwentyTen and TwentyEleven where it should appear and where those themes didn't use that core function.

This patch has already been committed and will make its debut in WordPress 3.2. If you're not running WordPress 3.2 beta yet but really do want this functionality, you can use the following snippet, just copy paste it into your (child-)theme's functions.php file:

function yoast_rel_author_filter( $link ) {
	if ( false === strpos( $link, 'rel="author"' ) )
		$link = str_replace ( '<a ', '<a rel="author" ', $link );
	return $link;
}
add_filter('the_author_posts_link','yoast_rel_author_filter',10,1);

This won't break your theme when you upgrade to 3.2, although by that time it's safe to remove it.

Note for theme Theme authors

This upgrade makes it even more important then before to have a link to the author's posts page / profile page underneath each post. Hence, with that, the importance of an authors page rises as well. You should allow authors to write a short bio, show off a picture (their gravatar?), and link to some other places like their Twitter, Facebook and Google Profile.

Luckily, this was made easy back with the release of WordPress 2.9, when user contact fields became filterable.

But that's not all!

As the help center article states, your posts and articles need to link to your profile page on that same site. Your Google Profile, in turn, needs to link back to that author page. So go and add the link of your author page to your Google+ Profile.

When someone likes or shares a URL on Facebook, data is used to create the title, description, image and other attributes to form structured information about that page via the Facebook Open Graph protocol. This article will show you how to optimise this data.

Facebook & Open Graph's XML Nameservers

Within the opening <html> tag, the Facebook and Open Graph nameservers need to be included to tell your browser and other parsers that it can expect tags other than HTML:

xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml"

an example end result might look something like this:

<html xmlns="http://www.w3.org/1999/xhtml" dir="ltr" lang="en-US"
xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml">

Adding some Necessary Facebook Open Graph Tags

Now that we have the XML nameservers in place we can now add a few Facebook Open Graph data entities to the site's header.

<meta property="og:title" content="<?php the_title(); ?>"/>
<meta property="og:description" content="<?php
  if ( function_exists('wpseo_get_value') ) {
    echo wpseo_get_value('metadesc');
  } else {
    echo $post->post_excerpt;
  }
?>"/>
<meta property="og:url" content="<?php the_permalink(); ?>"/>
<meta property="og:image" content="<?php echo get_fbimage(); ?>"/>
<meta property="og:type" content="<?php
  if (is_single() || is_page()) { echo "article"; } else { echo "website";}
?>"/>
<meta property="og:site_name" content="<?php bloginfo('name'); ?>"/>

A note about og:description - I have used the Meta Description from Yoast's WordPress SEO plugin to generate og:description. If the plugin is not installed then the post's excerpt will be used instead. On another note, og:descriptioncan allow up to 300 characters. If you're advanced enough you could replace the META description with a custom field and use that to generate a totally unique description just for Facebook!

Generating the best Image Thumbnail

In the example above, I have used the function get_fbimage();to generate the image thumbnail. Here's that function:

function get_fbimage() {
  $src = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), '', '' );
  if ( has_post_thumbnail($post->ID) ) {
    $fbimage = $src[0];
  } else {
    global $post, $posts;
    $fbimage = '';
    $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i',
    $post->post_content, $matches);
    $fbimage = $matches [1] [0];
  }
  if(empty($fbimage)) {
    $fbimage = "http://mydomain.com/default-image.jpg";
  }
  return $fbimage;
}

This code does 3 things:

1. Looks for a featured image
2. If there isn't a featured image, it looks for the first image within the_content
3. If there isn't a featured image or any image within the_contentthen use a default image

og:type - categorising your page type

og:type can describe the type of content the page has. This can encompass many things such as a website, blog, article, product, TV show and many more. Below is a simple example of treating each page and post as an article, and everything else within the site as a website:

<meta property="og:type" content="<?php
  if (is_single() || is_page()) { echo "article"; } else { echo "website";}
?>"/>

There are several types of page that can be found here. One way you could make og:type more advanced using custom fields. Let's say I have just written a post about a book I have just read, we can use book within the og:type. I can now insert a custom field named og-type and insert the value book. Once I've done this I can now edit the example above to create something more advanced:

<meta property="og:type" content="<?php
  $ogtype = get_post_meta($post->ID, 'og-type', true);
  if ($ogtype != '') {
    echo $ogtype;
  }  elseif (is_single() || is_page()) {
    echo "article";
  } else {
    echo "website";
  }
?>"/>

The code above looks for the value of the custom field named og-type. If there isn't a value then it to default values as shown in the basic example.

Some other Facebook Open Graph Tags

The Open Graph tags above are the required tags needed. Below are additional tags you can use to provide even more in-depth detail about that page or site.

Page ID

You can connect your WordPress site to Facebook via Facebook Insights. Once connected, you can view analytics for all sorts of Facebook features. Insert this code to connect your site to Facebook Insights:

<meta property="fb:page_id" content="1234567890" />

App ID

When you add any Facebook App, such as Facebook Comments, to your site you need to link the site to your Facebook Platform application:

<meta property="fb:app_id" content="1234567890" />

Admins

With some Facebook Platform applications, such as Facebook Comments, you don't need this tag as the admins are managed within the App itself. However, there are certain Facebook Platform applications that will need more management. This tag can be used sitewide or per page so is more useful on larger sites with multiple administrators and moderators. Simply create a comma separated list of admins by profile ID:

<meta property="fb:admins" content="1234,2345,3456" />

You can find your Profile ID by hovering over your Facebook profile picture and taking note of the value after set=pa., for example, mine is ?set=pa.223100916

Contact Info

You can embed your email adress, phone & fax numbers like so:

<meta property="og:email" content="<?php bloginfo('admin_email'); ?>"/>
<meta property="og:phone_number" content="+44 123 456 7890"/>
<meta property="og:fax_number" content="+1-415-123-4567"/>

Note that I have set og:emailto the WordPress admin email. You may want to change this if the admin email is not one for public knowledge.

Location

As we know, local search is on the increase. Open Graph have added location based tags which can be used for things such as Facebook Places:

<meta property="og:latitude" content="37.416343"/>
<meta property="og:longitude" content="-122.153013"/>
<meta property="og:street-address" content="1601 S California Ave"/>
<meta property="og:locality" content="Palo Alto"/>
<meta property="og:region" content="CA"/>
<meta property="og:postal-code" content="94304"/>
<meta property="og:country-name" content="USA"/>

Audio and Video

Adding audio and video can be very useful for Open Graph. A good example of how this is used is where you can click a video in Facebook and it will play it right there and then, instead of you having to visit the page directly to view it. Here's an example of how this can be used:

Audio (only supports MP3):

<meta property="og:audio" content="http://example.com/amazing.mp3" />
<meta property="og:audio:title" content="Amazing Song" />
<meta property="og:audio:artist" content="Amazing Band" />
<meta property="og:audio:album" content="Amazing Album" />
<meta property="og:audio:type" content="application/mp3" />

Video (only supports SWF):

<meta property="og:video" content="http://example.com/awesome.swf" />
<meta property="og:video:height" content="640" />
<meta property="og:video:width" content="385" />
<meta property="og:video:type" content="application/x-shockwave-flash" />

That wasn't so painful, was it?

You can check that your tags have been implemented correctly by using Facebook's URL Linter. You can find more information about the Facebook Open Graph protocol at ogp.me as well as at facebook.com.
