PageRank Explained

Google have a measuring tool called PR = Page Rank

Each page on the web will have PR rating from 0 to 10

*************************************************

What is PR and how is it calculated, and more importantly how do you increase the PR rating for your webpage?

PR is a value of importance, when your page has a low rating of 0 your site is far less important that a page that has a rating of 10

(If you run adsence on your website this will be reflected in the monetary value of your ads)

*************************************************

How does Google rank your web page?

Every web page that links into your web page is a vote and the more votes you have to your web page the more important it will become, also each vote represents a value.

As an example I posted an entry on a forum that included a link back to my main site and the PR rating for this backlink is 0.03 so if I had 10 of these backlinks at this value my page would have a PR of 0.30….  not even a rank of PR1.

Realising my PR was low I came to the conclusion we will need 100 of these backlinks at this value to give my web page a PR3 rating

Some back links to your site might not have a value of 0.03 it could be higher or even lower.

*************************************************

How is the value of each vote (Link) calculated?

In this example we will use 2 web pages with different PR ratings

The first web page has a PR of 2 and has 10 links going out.

2 Divided by 10 = 0.20

The second web page has a PR of 6 and has 100 links going out.

6 Divided by 100 = 0.06

The conclusion being you would be better off having a backlink on the lower ranked PR2 page because it has a vote value of 0.20 compared to just 0.06 from the higher ranked page.

The calculation of this example have been simplified to help you understand the basic concept, this is the real calculations Google uses

PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn))

The real Google calculation (Above) works out at about 85% of a Page Rankings value is used for outgoing links.

(If your page is rated PR1 85% of this will be used for outgoing links 0.85)

PR 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.

At this point we should state you do not give away your ranking by having outgoing links, you are not transferring your PR out.

In general most links back to your web page, either internal or external will give your PR a boost and are good for your website.

This should give you a basic understand of “Page Ranking” and help with any future plans you have to increasing traffic to your site.
