Re: How to calculate Page rank
PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be.

Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes cast for it. How important each vote is is taken into account when a page's PageRank is calculated.
PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.

Calculate the PageRank

To calculate the PageRank for a page, all of its inbound links are taken into account. These inbound links are the links from within the site and the links from outside the site.

The equation that calculates PageRank of a page is as follows -

PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))

This equation is the original one that was published when PageRank was being developed.

In the equation,
't1 - tn' = pages linking to page A,
C' = number of outbound links that a page has
'd' = a damping factor, that is usually set to 0.85.

So the equation simplifies to

PageRank of a Page A = 0.15 + 0.85 * (A "share" of the PageRank of every page that links to it)

"share" = the linking page's PageRank divided by the number of outbound links on the page.

Re: How to calculate Page rank
You can calculate the PageRank of any website or webpage simply by clicking on the following link - calculatepagerank.com calculate page rank
Just type the website name and click GO. Within few seconds, the pagerank of that website will be calculated and displayed (out of 10).
