Google PageRank™ explained. Optimise your site for the Google search engine
At the heart of Google’s Search Engine software is PageRank™, a system developed by Google’s founders Larry Page and Sergey Brin for the purpose of organising and ranking individual web pages using Google’s vast link structure, which it then uses as an indicator for each individual page’s value (pages are ranked on scale of zero to ten).
As defined by Google:
PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page’s value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves “important” weigh more heavily and help to make other pages “important.”
Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.
Simply throwing your web site address up on every guestbook, comments page or internet forum you come across wont achieve anything. Remember, high quality sites receive a higher PageRank™. The more high quality sites you get linked on (and the more relevant your own content is), the higher your own PageRank™ will be.
