Google Page rank Formula

Hello Friends,

This post will teach you in detail the formula of the page rank Google has decided. Guys if this formula is taken into consideration and worked upon then i am sure , your page rank will climb heaven. Google calculates the inbound as well as outbound links of a page to check its page rank.

The formula for that is as follows

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

That’s the equation that calculates a page’s PageRank. It’s the original one that was published when PageRank was being developed, and it is probable that Google uses a variation of it but they aren’t telling us what it is. It doesn’t matter though, as this equation is good enough.

Now lets calculate this formula.

Let us assume 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. Hence,

a page’s PageRank = 0.15 + 0.85 * (a “share” of the PageRank of every page that links to it)

Share = the page rank of linked pages divided by number of outbound links on the page.

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 is shared equally between all the pages that it links to.

From this, we could conclude that a link from a page with PR4 and 5 outbound links is worth more than a link from a page with PR8 and 100 outbound links. The PageRank of a page that links to yours is important but the number of links on that page is also important. The more links there are on a page, the less PageRank value your page will receive from it.
