What is Page Rank?
Page Rank can be simply defined to as Google's View of the importance of a page. The Page Rank of a website measures not only the number of links that points to a website, but the quality of the websites that provides the links.
Page Rank can be said to be the yardstick for measuring the importance of a web page.
According to Google Technology "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 considerably more than the sheer volume of votes, or links a page receives; for example, 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." Using these and other factors, Google provides its views on pages' relative importance."
