Google Page Rank Algorithm

Page Rank is named after Larry Page. Page Rank is a rank given to each and every page across the world depending upon the number of back links to that particular page.

We cannot say that all the pages do get a page rank according to this formula. Just for purpose the formula used to calculate PR is


Page Rank Formula

1 PR1 = 101 PR0


1 PR2 = 555 PR0 = 101 PR1


1 PR3 = 3,000 PR0 = 555 PR1 = 101 PR2


1 PR4 = 17,000 PR0 = 3,000 PR1 = 555 PR2 = 101 PR3


1 PR5 = 93,000 PR0 = 17,000 PR1 = 3,000 PR2 = 555 PR3 = 101 PR4


1 PR6 = 508,000 PR0 = 93,000 PR1 = 17,000 PR2 = 3,000 PR3 = 555 PR4 = 101 PR5


1 PR7 = 2,878,666 PR0 = 508,000 PR1 = 93,000 PR2 = 17,000 PR3 = 3,000 PR4 = 555 PR5 = 101 PR6


1 PR8 = 15,818,412 PR0 = 2,878,666 PR1 = 508,000 PR2 = 93,000 PR3 = 17,000 PR4 = 3,000 PR5 = 555 PR6 = 101 PR7


1 PR9 = 85,504,929 PR0 = 15,818,412 PR1 = 2,878,666 PR2 = 508,000 PR3 = 93,000 PR4 = 17,000 PR5 = 3,000 PR6 = 555 PR7 = 101 PR8


1 PR10 = 462,188,805 PR0 = 85,504,929 PR1 = 15,818,412 PR2 = 2,878,666 PR3 = 508,000 PR4 = 93,000 PR5 = 19,000 PR6 3,000 PR7 = 555 PR8 = 101 PR9





Wee cannot say that all pages having a PR3 link is a PR1. Google update the page rank of all the pages only a few times in an year. When we see SERP, PR is given very less importance. There are several factors are considered before ranking a page such as relevancy of linking page.

Many people might think that search rankings are done based on only Page Rank. But that is not true. Actually, the ranking is done based on various criteria and PR is also one of the metric that Google considers among many metrics. And as per our researches, the % of importance given to page rank as a metric is reducing in each update of Google.

When the PR of any page is higher, then the value will be very high. As mentioned above but not directly affect the rankings. So give little importance to page rank and do not consider it as the only metric.

Article will be updated as per the latest update।
