1st> What is Page Rank: Page Rank is a rank of a particular page which is a scoring mechanism of Google for determining a page’s importance by Link Popularity. Accordingly it determines a site’s importance also.
2nd> How it is calculated:
To compute the Page Rank for a page, all of its inbound links are taken into account. These are links from within the site and links from outside the site.
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
That's the equation that calculates a page's PageRank.
In the equation 't1 - tn' are pages linking to page A, 'C' is the number of outbound links that a page has and 'd' is a damping factor, usually set to 0.85.
We can think of it in a simpler way:-
a page's PageRank = 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.
