Page Rank is one of more than 100 factors Google uses in the ranking of you website and your resulting position on their search engine. Page Rank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page’s importance from the votes cast for it.
How important each vote is taken into account when a page’s Page Rank is calculated. Page Rank is Google’s way of deciding a page’s importance. It matters because it is one of the factors that determine a page’s ranking in the search results. It isn’t the only factor that Google uses to rank pages, but it is an important one.
The following will give you an idea of how many inbound links and what PR those inbound links need to be, for you to obtain the desired Page Rank for your pages. The following page rank algorithm equation is the relationship between two pages X and Y, with the below example page A receiving an inbound link from page Y.
PR-X = (0.15) + (0.85 x PR-Y / TOL-Y)
PR-X is the Page Rank of Page X, PR-Y is the Page Rank of Page Y, and TOL-Y is the Total Outbound Links of Page Y.
For example if you get a inbound link from a page that has a PR of 6 and on that page there is a total of 6 outbound links (counting the one to your page), a PR of 1 will be added to your page: 0.15 + (0.85 x 6/6) = 1. If that one inbound link adds a PR of 1 to your page, and you wanted a PR of 5 it would take 5 similar inbound links.
By similar I mean pages that have a PR/TOL ratio of 1. That could be a PR of 5 with 5 outbound links, or a PR of 7 with 7 out bound links and so on. A PR/TOL ratio of 1 will add to your page a PR of 1. Using the PR/TOL ratio simplifies the Rage Rank algorithm equation and makes it easier for you to evaluate what PR an inbound link will add to your page. When you are looking for inbound links just divide the PR of the page by its outbound links and this will give you a general idea of the PR an inbound link from that page would give you.About the Author:Submit Express is one of the longest running SEO companies in operation since 1998.
