My colleague Roy made me laugh today, and not a little, over this very geeky SEO joke:
Me: "Hey, we're ranking for duplicate content."
Roy: "How often?"
Now, if you can laugh about that, you know you're doing good as an SEO and probably bad in your personal life :). Any more SEO jokes you guys want to [...]

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 [...]

Dave Sifry posted on the Technorati blog that Technorati has updated it's design. And I actually really like it! There's one thing though... My colleague Roy pointed at the source code, especially the tag cloud... Come on guys, you can do better than that!

As requested by Ruben, I've added Clicky to the statistics detector Greasemonkey script, upgrading it to version 1.3.8, and installed Clicky on this site too. The interface looks quite good, I'll test it over the next few days and let you guys know what I think.

Especially with the new autodiscovery feature for sitemaps around, it becomes very easy for a scraper to find any and all URL's in your site. So in my opinion, they are a bit too warm of a welcome.

I've been using Tele2 for a while now while on my old address, it was slow at times, but it usually worked, so I was pretty satisfied. I'm not anymore though... We've been moving to our new house over the last weekend, and I had arranged for our phone and internet connection to be moved [...]

Since moving the seo blog to the main URL worked so well on css3.info, (it came out of the last PR update as a PR7 and has had more search referrers since), I decided to do the same here. Let me know if you find any errors, but I think it all went smoothly. All [...]

Imagine you're like me, and you like WordPress so much that you write plugins for it. People start writing about these plugins and they, of course, link to you. You see these pages writing about you show up in your referrer stats and of course you go and have a look at what they're writing [...]

Subpages of category archives were improperly 301'd back to the main category page... Fixed that now, so update NOW: the permalink redirect plugin.
I fixed the title for category subpages too btw, check how this works:

} else if ( is_category() ) {
echo single_cat_title("");
echo " archives - ";
bloginfo('name');
if (get_query_var('paged') [...]
