I added a new permanent link to my SEO cateogory in the sidebar today. It is SEOmoz.org. All sorts of search engine optimization tools and articles are provided. Be sure to check out the article Search Engine Ranking Factors, as it is a masterpiece of clear organization and informative writing. The article surprised me by giving h1 tags on the page “Inconsequential Importance.” I’d always heard that they were important. You have to register to use some of the tools.
