Google Page Rank

GOOGLE PAGE RANK

Page rank is the numerical value that represents how important a page is on the web.

Working of PR

* Bad incoming links dont have impact on your web page rank.
* PR is not considered based on backlink relevancy or backlink duration.
* Content is not taken into account, while considering PR.
* To have a overall good PR, the PR of each inbound link is also important.
* PR is calculated for each page individually.
* It doesnt range from o to 10. Rather it is a floating point number.
* It is calculated based on logarithmic scale.
* Google update page rank every few months.

The basic formula for calculating Google page rank is

PR(A) = (1-d) + d(PR(t1)/c(t1) + ......+PR(tn)/c(tn))

Where,

PR(A) - Pages linking to the page A.
t1-tn - Pages linkink to page A.
c - No of outbound links a page have.
d - Damping factor -> 0.85
