I'm completely shocked about the popularity of my recent exposition on search ranking factors. The traffic has been more than substantial, bringing about 10,000 unique visitors to SEOmoz since Thursday. A normal four-day period would have around 1,600, so it's definitely a shake-up, not to mention the links (350+ already).

There has been plenty of criticism (both valid and less so), and I take full blame for that. The initial article was not authored with the care and precision that I would have given to a document that had the eyeballs of thousands. I've made some initial changes in the wording to make it clear that my intentions are to show what "may" impact rankings and not to make recommendations about what web content creators should or should not do, nor to present all of the items as fact - they are virtually all speculation (albeit highy informed speculation).

In seeking to make such a highly read article more valuable, I've sought the help of some SEO experts in the field to vote on each of the ranking factors and add their own comments (as I promised at TW). From Danny Sullivan to Jill Whalen to Ammon Johns and Bill Slawski, they've all agreed and I couldn't be more pleased. I hope that by pulling together this group of a dozen experts, we can make an article that can serve as a reference for a long time to come. After all, it's already been tagged by almost 400 people at del.icio.us - so it's my duty to see that it's as comprehensive and accurate as possible. Many thanks to the contributors, all of whom will get recognition in the finalized article (which should hopefully be ready by Thurs. of this week).
