What is Page Ranking?? Simply speaking Page Rank is a 'vote', by all of those other pages on the internet, about how important a page is. A link to a page counts as a vote of support. There is no support (but it is definitely an abstention from voting rather than vote contrary to the site) if there's no link. How is Page Rank Used? Page Rank is one of the techniques Google uses to determine a page's relevance or value. It's only 1 part of the story when it involves the Google listing, but the other factors are discussed elsewhere (and are ever-changing) and Page Rank is exciting enough to deserve a paper of its. When you have installed the Google toolbar (http://toolbar.google.com/) pr can also be displayed o-n the toolbar of your browser. However the Toolbar Page Ranking just goes from 0 - 10 and is apparently something like a logarithmic scale: Toolbar Site Rank: (log base 1-0) Real Pr 0 0 - 10 1 100 - 1000 2 1,000 - 10,000 3 10,000 - 100,000 4 and therefore on.. We are able to not know the exact details of the size because, as we'll see later, the utmost PR of pages online changes every month when Google does its re-indexing! If we assume the scale is logarithmic (though there's only anecdotal evidence for this at the time of writing) then Google can just provide a toolbar PR to the highest actual PR site of-10 and scale the remainder accordingly. If people desire to dig up further on the link, there are tons of databases people should consider investigating. Also the toolbar sometimes guesses! The toolbar frequently shows me a Toolbar PR for pages I have only just uploaded and cannot possibly be in the list yet! What appears to be occurring is that the toolbar discusses the URL of the page the browser is displaying and strips off anything down
