How is Page Rank Determined?

Backlinks are considered as votes for every page. But they don't have the same power. It depends on where the link is coming from. With this theory Pagerank of each website it calculated. In reality the calculation is a bit more complicated equation that can be displayed as followed:

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

Evaluating the Pagerank is a never ending process because in order to get the right PR for website A, we need to know the exact PR of all the other pages linking to that page, but at the same time the PR of all those other pages is based on the PR's linking them.

This is why Google's updates of the PageRank take so long every time. In order to get more accurate number for PageRank Google updates that number on regular bases.

One thing is clear for sure, any link pointing to your website increases the overall Pagerank. It's always a good to get a backlink from a website with higher PageRank, but the number of outgoing link from that website matter also.

Two links coming from 2 different pages with the same PR will have different weights if the number of outgoing links are different from each of those page. The page that has less outgoing links will have higher weight, then the one with many outgoing links.

If you are interested in increasing your overall page rank you can contact a local SEO Company for a consultation. Keep in mind that higher Pagerank will give you a better visibility on the web, it you will get a higher traffic.
