I’ve been playing around with WP-Googlestats for some blogs, and I noticed something I really didn’t think about until now.

I’m doing some work on a site which has like 4,500 pages indexed with a PHPSESSID in the URL, causing some major duplicate content problems. I got the server admin to disable the PHPSESSID’s by adding the following to the vhost config: I also wanted Google to get a clean URL when it decided to »

Update: (Aug 4 2007) the stuff below is no longer necessary, all major search engines now treat underscores and dashes exactly the same, as word separators! A year or so back, I was using underscores in my URL’s on this site for spaces, and I decided to switch them to dashes, since several people, including »

This query gives a result I hadn’t seen before (image), the same page was indexed with both a single trailing forward slash, which is of course normal, and with a double trailing forward slash… This is of course a duplicate content issue, especially when people link to the double slash one by accident.

My friend Jaimie Sirovich sent me a chapter of his upcoming techy SEO book. More specifically, he sent me the chapter on cloaking, geo-targeting and IP-delivery.

MSN launches Dutch Digg clone, but forgets spam prevention

15 February 2007 by Joost de Valk » - 30 Comments

Recently (I honestly don’t know when), MSN launched a Digg clone in the Netherlands, called MSN reporter. You can submit your story, and others can vote for it or against it.

I got an email from Mozilla’s director of product management Sherman Dickman today, that my sortable table script wasn’t sorting numbers above 1 million which have comma’s in them correctly (they do have a lot of Firefox downloads ;) ). The problem was caused by the fact that replace only replaced items once, where they »

They “invented” blogsearch, and did a LOT for the webdevelopment and blogging community. Now Technorati, it turns out, is working on the microformats search I asked for only two articles ago (it was there before that, I just didn’t know about it)… Check it out in Technorati’s Kitchen.

Googling for microformats

22 January 2007 by Joost de Valk » - 14 Comments

Imagine, you can type in a query like “joost de valk class:vcard” and Google comes up with my contact page, because that has a vcard class in it’s markup, the main class of the hCard microformat.
