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.�
