PAGE RANKS computed

PageRank says nothing about the content or size of a page, the language it’s written in, or the text used in the anchor of a link!

So what is PageRank?

In short PageRank is a “vote”, by all the other pages on the Web, about how important a page is. A link to a page counts as a vote of support. If there’s no link there’s no support (but it’s an abstention from voting rather than a vote against the page).

FORMULA normalized link matrix of the web

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))
