28 August 2007 by Joost de Valk » - 264 Comments

This weekend I was reading about Shoemoney being extorted by a DMOZ editor. I thought: heck, I’m a DMOZ editor, I don’t want to be associated with stuff like that, let’s see if I can do anything to help. So I posted something like that in the commentthread to the above post, and I added »

noindex,follow your WordPress search result pages

16 August 2007 by Joost de Valk » - 9 Comments

The webmaster guidelines advise you to prevent your search result pages from being indexed, WordPress doesn’t do that by default (yet), so I’ve written a small noindex-search plugin which takes care of that by adding a meta robots noindex,follow tag to search result pages.

7 August 2007 by Joost de Valk » - 2 Comments

On the SERoundtable the question is raised whether you can check if a site 301 redirects to your website, referring to a thread on the SEW forums and an article by Aaron Wall. That seems quite simple to me, as most of the times you’ll see clicks coming in from sites on which your own »

4 August 2007 by Joost de Valk » - 5 Comments

Sometimes you’re browsing around and wondering whether a blog is a WordPress or not (at least I am)… So I created a small script that detects that, and show the version of the WordPress as well.

Perfectly coded AJAX with fallbacks, and still no Google love?

2 August 2007 by Joost de Valk » - 1 Comment

You’ve probably seen it too… Great looking websites coded with all sorts of fancy AJAX functions, and it’s done absolutely right. If you disable javascript, all the links that were first used to show content or do an action on the current page, now take you to a new page on which the content you’re »

Dave Davis dropped me a line to tell about the Google Global Firefox extension they have just released, which allows you to search Google with geo targetting for different countries without having to edit the URL by hand. It’s quite useful, I dare say, so check it out!

I’ve been playing around with the URL parameters Google has to offer a lot lately, mostly after the de-personalized search stuff. I’ve now built a list of these parameters and created a PDF cheat sheet file with all of them in there. Included in this PDF are links to the documentation for the values some »

Blogspam works, but only in large quantities

28 June 2007 by Joost de Valk » - 17 Comments

Dave Davies did some research on whether nofollow links still pass some linkjuice, and as it turns out (which we knew of course) it does, a bit… So, for your blogspam to be useful, you have to do it in very very large quantities :)
