Looks like the folks at
SEOmoz have put together a comprehensive list of Google Ranking Factors:
SEOmoz | Google Search Engine Ranking Factors"This document represents the collective wisdom of 34 leaders in the world of organic search engine optimization. Together, they have voted on the various factors that are estimated to comprise
Google's ranking algorithm (the method by which the search engine orders results). The result is a resource of incredible value - although not every one of the estimated 200+ ranking elements are included, it is my opinion that 90-95% of the knowledge required about
Google's algorithm is contained below."
I wonder if the engineers at Google sit back and rub their palms together at this stuff or just laugh!
