Google Pagerank Explained, Defined, Best Reference Resources

If you are serious about improving your Web site relevance on Google (and as a consequence on several other major search engines) you should understand quite well what Pagerank is and how it works.

Pagerank is a an algorithm that Google utilizes to rank its search results in presence of multiple resources matching a certain query. In very simple words Pagerank evaluates and ranks Web sites according to a computed value determined by the number of other sites linking to them. The way the Pagerank value is computed makes Pagerank somewhat immune to artificial linking efforts.

In order to provide the greatest understanding and to allow an exhaustive mini-guide to Pagerank understanding I have researched and listed here below the most interesting and valuable resource on this topic that are available online.
Including the original Stanford paper from which the whole thing started.
