Search Ranking Factors - Weighted

SEOMoz solicited feedback on the top search ranking factors that determined where a site would be ranked on a Search Engine Results Page (SERP) in April of 2007. The graphically pleasing and feedback rich survey was very well done & deserves a lot of praise — probably one of the reasons for Rand Fishkin & SEOMoz’s quick elevation into the SEO Industry’s elite experts and websites. However, one thing you can’t do with the search ranking factors search results is sort the list. As a result, I took it upon myself to retype them all and sort it here:
