Page Rank Concept

Page Rank concept: Is it important for site ranking?

Page Rank is a patented algorithm by Stanford University to assign weighted importance to a web page determining its relevancy on the World Wide Web on a scale of 0 to 10.

Page Rank was developed at Stanford University by Larry Page and Sergey Brin as part of their research project.

The theory behind:
Page Rank is based on the linking structure on a page. The more the links pointing to a page, the more will be the page rank. Google believes that if many links are pointing to a link, then that page must be of value to the searches and it assigns the page a high weighted value.

Page Rank: Google Toolbar
Page Rank can be viewed on the Google toolbar. Google has not disclosed the algorithm for calculating the page rank but it is in simple words measure of the popularity of a web page.

The Google directory page rank is measured on a scale of 0 to 8.

Page Rank Algorithm:

Page Rank of a page is the summation of all the PR’s of the links pointing to that page.

Thus if page A has a 4 links pointing to it then the PR of A will be:
PR(A) = PR(1) + PR(2) + PR(3) + PR(4)
If some page is giving links to other pages also then the PR of that page is equally divided among all the other pages.
For example if page 2 has a PR of 4 and it is linking to 4 pages then each page will gain a PR of 1.

Thus, weighted PR is calculated as
PR(A) = PR(1)/(links from 1) + PR(2) /(links from 2) + PR(3)/(links from 3) + PR(4) /(links from 4)

According to the founders of Google, the sum of all the PR’s to a page is 1.

Conclusion:
Though PR is a good indication of the popularity of the site, but it is not the only factor. The main focus of any one developing the site should be to provide quality content to its visitors and not bother much about PR. If your website is delivering quality data then it will definitely get good PR and thereby online visibility.

Always remember “ Content is the king on Internet. Rest all follow”.
