PageRank Distribution Removed From WMT. Hey folks, Re: Toolbar: My impression is that PageRank in Toolbar is aimed more at the casual browser of sites who wants to get a general feel for the authority of a page.
For this reason many people still believe we should leave it in Toolbar. Toolbar isn't primarily aimed at site owners who are looking for precise & reliable metrics that they can judge their site by or make decisions by. That's one reason it made sense to remove it from Webmaster Tools, which is designed specifically for site owners in a way that Toolbar is not. Personally I would love to see us remove PR from the Toolbar, but mine is not the only opinion in Google and the folks I have most contact with--site owners--aren't the only users or stakeholders of Toolbar. FAQ: Crawling, indexing & ranking - Google Webmaster Help. PageRank sculpting. People think about PageRank in lots of different ways.
People have compared PageRank to a “random surfer” model in which PageRank is the probability that a random surfer clicking on links lands on a page. Other people think of the web as an link matrix in which the value at position (i,j) indicates the presence of links from page i to page j. In that case, PageRank corresponds to the principal eigenvector of that normalized link matrix.
