/in /by

We get so many emails asking for us to link to other sites for a returning link. Take care when considering this as the wrong link could cause you more problems that its worth.

Outbound links are links to another site, have you ever wondered what happens to your page rank when you create links to other sites. If you are now asking yourself what is my page rank then lets start here:-

Google’s ranking influencer, the Google PageRank (PR) is the topic of many discussions in the Search Engine Optimisation World and SEO companies all take account of their observations to sites page ranks.  The way Google PageRank calculation works is not clear as is anything Google do. 

Google PageRank (PR) is calculated for every webpage in Google’s database and this can from 0 to 10. The BBC have a page rank of between 6 and 8 so it is not easy to get a high page rank. We recommend installing Google toolbar with the Page Rank tool enabled to show you Page Rank as you browse. Google keep secret there true PR value but SEO people say it varys from 0.15 to infinite. A true representation is converted to a value between 0 and 10, zero being low to ten being high.

The calculation of the PR for a page is based on many factors such as the quantity and quality of webpages that contain links to that specific page.

Google PR is formed by the following formula:

PR = (1 – d) + d * SUM ((PR(I->A)/C(I))

Where:

  • PR is the PageRank of your page.
  • d is the damping factor which is usually set to 0.85
  • PR(I->A) is the PageRank of page I containing a link to page A.
  • C(I) is the number of links off page I.
  • PR(I->A)/C(I) is a PR-value page A receives from page I.
  • SUM (PR(I->A)/C(I)) is the sum of all PR-values your page receives from pages with links to your page.

So to break this down the Page Rank of a page is calculated by the Page Rank of every page that has a link to your page.

For every page I that points to your page, the Page Rank the pages that point the your page will be divided by the number of links from these pages.

These values are cumulated and multiplied by 0,85. Finally 0,15 is added to this result, and this number represents the Page Rank of your page.
