I found a great article at seomoz.org, about Google’s Ranking Factors, it’s a must read. Top SEO Practitioners like Aaron Walls, Bill Slawski, Jill Whalen, Michael Gray, Danny Sullivan, and others voted on the factors they estimate are the most important used on Google’s Ranking Algorithm to determine the placement of a web site in the search engine result pages (SERP’s) when an Internet user is doing a specific search. Google’s Ranking Algorithm is the mathematical formula they use to calculate which results to display and that are most suitable to the searcher query.
Ranking factors are attributes present in a Web page and are used to tell Search Engines what the web page is about and by which search engines determine the importance of a Website based on the website’s relevance and related keywords…
So seomoz.org gave to the task, this is their second and most updated version of the ranking factors. They are presented in several categories, each evaluated in several related components. The following are the most significant factors taken in account for the evaluation of factors that are considered to be important when doing SEO for a Web Page:
