SEO Ranking Factors for 2009

I just spotted the results of an interesting survey over at SEOmoz.com that is extremely helpful in outlining what exactly is and is not important when it comes to SEO ranking factors that you should be keeping tabs on if you want to rank well across most of the major search engines.

According to SEOmoz Co-Founder & CEO Rand Fishkin, every two years, SEOmoz surveys top SEO experts in the field worldwide on their opinions of the algorithmic elements that comprise search engine rankings. This year features contributors from the US, UK, Canada, Australia, New Zealand, Iceland, the Ukraine, the Dominican Republic and many more.

I have to agree with him that his document, representing the collective wisdom of expert practitioners, is probably one of the most useful resources for SEO practitioners of all varieties, helping to provide transparency into what matters (and doesn’t) for best practices in search engine optimization.
