PageRank

PageRank is a system used by Google to help determine a web page's relevance or importance. Visible PageRank - a number from 1 to 10 and displayed in the Google toolbar - is updated only every few months. It is a rough approximation of REAL PageRank, which is constantly updated. Google says it 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".Sometimes website owners say something like, "My site has a PageRank of 6." What they mean is that the main page of their site has a PageRank of 6. Websites don't have PageRank. Individual pages do.
