The girls and boys over at Google Webmaster Central have been busy on the Google Developer Day. Now that's all nice, but when I was searching for something on their blog for "nofollow", I got 4 results:

Now as you can see, 3 out of the 4 results here, are feeds... All these three feeds show [...]

I was working on adding a new metric to the domain info tool, being the "deeplink ratio" (the number of links to other pages than the homepage, divided by the links to the homepage * 100), when I found out Yahoo's SiteExplorer API is giving me wrong results. It returns way less links than the [...]

I'm a huge fan of Google Webmaster Tools, and I've written a tool for it which seems quite popular, (and might get an update soon). I've been noticing that people find my site by searching for the search term "how to use Google Webmaster Tools", so I thought I'd post a guide of how I [...]

I got some e-mails and even a phone call that my domain-info tool wasn't working properly. The reason was that the link: command in the Live search API seems to have been disabled, and my code threw out the complete SOAP error... I've removed that. For now MSN inlinks will return no results, I'll probably [...]

I love Google Webmaster Tools, especially when it started showing external links. This link overview left me and quite a lot of other SEO's longing for more though, as we all wanted more info on that page. I have now created a Greasemonkey script to show the PageRank of the page linking to you, and [...]

In response to my previous post about unlimited API queries, I was urged by David Sifry, CEO of Technorati, to contact the Technorati developers and work out a way to get my script working through the API.

Want to see the Technorati rank and the number of inbound links for a page? I wrote a Greasemonkey script that shows you just that, it does that by opening the search page for the current URL on Technorati and finding those values on it.

A while ago I started writing my Greasemonkey script to detect statistics programs, this script has been evolving since, and now has gotten it's own page, so check out the Greasemonkey statistics detector.
If you find any statistics programs it doesn't recognize, please do let me know so I can update it.
Update: I added another 4 [...]

Sometimes, while going through results for certain keywords, you will find that some of your competitors use free statistics programs. In a lot of cases, you can access those statistics, which usually contain very valuable data like keywords and referrers. Sometimes people will hide the usually obliged buttons for these scripts, but you can find [...]

This script has been replaced by a new version, which now has it's own page. 
I recently (as in, yesterday) bought a Mint license for this site, and am now very enthusiastic about it. Now i've always been using Google Analytics, and since i'm very interested to know what kind of stats package other people use, [...]
