Page Rank Algothm

The major algorithm which defines the search rank of a web site is Page Rank algorithm. Page Rank defines how important this web page in the eyes of google. Here I am not going to tell how to improve page rank. Instead I am going to explain what is Page Rank algorithm.

The google Page Rank algorithm is defined based on the number of inbound links to the web page and the page rank of the sites which links to us. The total number of out bound links on the site which links to us is also important. So the google Page Rank algorithm is provided below.


PR(A)= (1-d) + d [ PR (ti) / C (ti) ]

Where

PR (A) = Page Rank of web page A

d= Damping factor usually equal to 0.85

ti = Pages linking to web page A ,where i = 0 to n

C(ti) = number of out bound links on ti

So the detailed Page Rank algorithm is provided below.

PR(A) = (1-d) + d [ PR (t1)/C(t1) + PR (t2)/C (t2) + .....PR(ti)/C(ti).... + PR (tn)/C(tn)]


So the page rank algorithm shows that the quality(Page Rank) of the in bound link is very important. Second thing is the total number of out bound links on the page which is linking to us is also very important. As the number of out bound links on the page increases the amount of points transferring through an out bound link decreases.
