Calculation Of Page Rank

No one exactly knows how page rank is concluded but over the time people have concluded many things. Lets take an example:-

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

Above is a Google Page Rank algorithm, which was released in the development of Google algorithm. Thats right the actual algorithm equation .

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.

A simpler way to think of it is:

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 is divided by the number of outbound links

A page “votes” an amount of PageRank onto each page that it links to. The amount of PageRank that it has to vote with is a little less than its own PageRank value (its own value * 0.85). This value will be shared equally between all pages.
