Professional WordPress Plugin Development

As you might have noticed I’ve recently started reviewing WordPress plugins. I do this for free, because I think both users and developers benefit from peer reviews of plugins. I’m not saying all my plugins are perfect, they’re not. I try hard though and if someone reviews my plugin I’ll happily learn from what they…

Using a namespace for your functions and classes

An often made mistake by WordPress developers is to use to generic function and class names. For instance, if you’re building a plugin to do with YouTube, using a class name “Youtube” is bound to cause issues: if a user has multiple plugins dealing with Youtube, he or she could very well end up with…

WordPress HTTP API

Why you should want to know about the WordPress HTTP API? Well, some WordPress installs may have CURL installed for instance, others may not. On some installs you’re allowed to do file_get_contents to external URLs, on others you’re not. If you’re relying on these features to work, your plugin might not work for a lot…

Why WordPress and some of my plugins require PHP 5.2

WordPress 3.2 will require PHP 5.2 or higher, as a result of which I’ve decided that my WordPress SEO plugin, currently still in beta, will also require PHP 5.2 and I will probably start having the same requirements for future version of my other plugins. This saves me time coding and testing against a version…

WordPress Plugin Review

I’ve decided to start doing plugin reviews on this blog, I get so many questions from people asking “is this a good plugin”, “is that a good one”, “can I trust that plugin”. It’ll probably help a lot more people if I start doing these reviews publicly. So, to start this, I’ve created a form…

11 Top WordPress Plugins Every Blog Should Have

WordPress in itself is a decent system but it can be made into a rock solid blogging beast. Adding top WordPress plugins can make WordPress into the Swiss Army Knife of blogging: just pull out whatever functionality you need for your specific blog! Many people have asked me for my list of top WordPress plugins.…

HTML Sitemap for WordPress

An HTML sitemap (as opposed to an XML sitemap) is often mentioned as being useful for SEO. They certainly are if you use them wisely (and especially Bing seems to like them at times), but I like them even more for the fact that users like them a lot. There’s plenty of plugins out there…

Killer Performance Tips from the Expert

My business & podcast partner Frederick Townes, who also happens to be the CTO @ Mashable.com, has finally finished a long awaited (by me at least) post covering lots of the performance tips he’s applied at Mashable (I hope you’ve seen their awesome redesign) and in other projects to make the sites faster despite having…

Turn your commenters into subscribers!

Only a small percentage of your visitors leave a comment. This group of people is probably also interested in subscribing to your newsletter, if you have one. So I created a method to add a “subscribe to my WordPress newsletter” checkbox to my comment form a couple of weeks ago. The result? 40 new subscribers…

Tools To Improve Your Online Marketing Campaign

I recently gave a presentation at the Bol.com partner event about tools I use every day for my online marketing campaigns and site analyses, and I thought it’d be cool to share them with you in a post as well, even though for some of you this list might be a bit basic. Google Analytics…
