Google Description of Page Ranks
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”.
The value of a ranking increases by a magnitude of ten for each rank. For example a site with a rank of six will be ten times more important then a rank five and one hundred times more important then a rank four.
So I was looking at page ranks today. My new game development blog has a rank of zero, however my old development blog has a rank of three and this blog has a rank of four.
Interestingly I noticed that my myspace page has a rank of three, where as my friends have page ranks of zero, making my myspace page one thousand times more likly to come up as a google search result then their pages. How can this be? My page is a lot lamer then most of theirs and a whole let less interesting in many cases, and most of them have more friends then I do. The only answer can be my other blogs which all link to my myspace page, resulting in increased importance for the myspace page.
How does this effect the myspacers? If your in my top 12 or leave a comment on my page, the resulting link will increase the importance of your page and in turn the pages of your top friends and those who have commented on your myspace page… and their pages as well…
