Google's Page Rank explained!

A high PR by google is one of the dreams that a webmaster wants for his website. Although, Google Page Rank has nothing to do with the traffic that a website receives but it can be used to find the importance of the website in Google's eyes.

As of today, I wanted to post an article as to how Google actually calculates the PR.

Many of the people out there might have thought that Google' PR consists of many of the complex mathematical operations that would take the genius of a scientist to understand their page rank formula. To their dismay the page rank formula is an easy equation.

Page Rank (X) = (1-Y) + Y { PageRank(W1) + ... + PageRank(Wn) }

(where X is the page rank) ------------          --------------

                            Z(T1)                    Z(Tn)

• PR(X) is the PageRank of a page X.

• PR(W1) is the PageRank of a page W1.

• Z(T1) is the number of outgoing links from the page W1.

• Z(Tn) is the number of outgoing links from the page Wn.
  

• Y is a damping factor in the range 0 <>

The PageRank of a web page is therefore calculated as a sum of the PageRanks of all pages linking to it (its incoming links), divided by the number of links on each of those pages (its outgoing links).
