To calculate the PageRank 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. 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.

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.

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.

Is it real formula to calculate pagerank?
Happy to get it, thanks

Personally, I don't believe in Page Rank. Page rank has no value nowadays. The most important thing you should concentrate on is the keyword rankings in SERPs. This is what going to give you benefits through the search engines.

According to Sergey Brin and Lawrence (Larry) Page, Co-founders of Google, the PR of a webpage is calculated using this formula:

PR(A) = (1 - d) + d * SUM ((PR(I->A)/C(I))

Its better concentrate on Quality of Backlinks and writing Original Content. Just leave that to the Googler..!!

It is very difficult to understand this algorithm.

Nice information.Page Rank is based on lot of factors and it is updated time to time by the Google.

Thats really a nice information, it will be very useful to many SEO people

I think pageRank depend on Back link Quality.

Page Rank of website is calculated by the number of dofollow backlinks from different domains.

Great..

PageRank is calculated is by the number of incoming links (also called backlinks) a site has.
