PageRank extends this idea by not counting links from all pages equally, and by normalizing by the number of links on a page. PageRank is defined as follows:

We assume page A has pages T1...Tn which point to it (i.e., are citations). The parameter d is a damping factor which can be set between 0 and 1. We usually set d to 0.85. Also C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows:


PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

Note that the PageRanks form a probability distribution over web pages, so the sum of all web pages' PageRanks will be one.

Following eqation I suggeste which has been very helpful indeed :-

"Focussed website content + Ethical SEO practices + Link building with good relvant website sites"

Getting crazy for too much Page rank is not required really and does help really .I have seen many websites where just by increasing the Page Rank factor alon their search enigines position has not improved.Quality and theme of the websites with appropriate anchor text makes the difference .

SEO need patience and hard work .There is nothing like magic or short cut for overnight success.
