Matt Cutts is the head of the webspam team at Google where he specializes in search engine optimization (SEO) issues. He is known in the webmaster and SEO community for applying Google’s Quality Guidelines. Before working in the Search Quality group at Google, Matt worked at the ads engineering group and on Google’s SafeSearch. The point is, unlike many “SEO Professionals” who only claim to know what they’re doing, Matt Cutts is well respected because he really does!
Matt didn’t really say too much specifically about WordPress, but the few things he did say are worth mentioning. First, he said that WordPress is a “great choice” for SEO because it solves “80-90% of Search Engine Optimization (SEO)”. He said that’s why he uses it and also why he needs so few plugins; Akismet, Cookies for Comments, FeedBurner FeedSmith, and WP Super Cache to be exact. That’s pretty amazing! He also mentioned that he uses /%postname%/ for his WordPress permalink structure, which I think is pretty standard among many SEO professionals. That’s really about all he said that was specific to WordPress, but he definitely has plenty more to say.
