Google’s PageRank (PR) is one of the most sought after web page attributes. The original idea was that a link from a web page to other site’s web page was basically a vote for that page. Google then used the number of inbound links (IBL or more often called backlinks) to a page to decide its importance. Based on this calculation (however there are many other factors, too) Google ranked the page and decided where it should appear in the search engine results (SERP).
Google uses scale of measurement for PageRank from 1 to 10. The lowest possible PR is PR1, the highest is PR10. The new websites tend to have PR0 which essentially means that they are indexed but they have no PR yet. Here is the official Google’s explanation of the PR.
The table above is only for a better imagination of how the the PageRank is calculated. Only Google knows the exact formula though. When building backlinks for your website remember that quality is more important than quantity. Try to get few higher PR links instead of bunch of low ones. In addition, you must be patient. Google updates the PR averagely every two months (the longest documented period of time between two PR updates was 122 days).
I’m working very hard on getting many relevant quality backlinks. Currently, according to dnScoop, there are totally 2,189 pages that contain a link to netcovered.com (Smart PageRank shows only 1664 though…). I will try to improve this number even more and I hope that during next PR update Net Covered will jump to at least PR3.

Google PageRank Formula
The thing is that nobody actually knows how the PageRank is calculated (except Google of course) but webmasters have discovered over the time the possible algorhitm that seems to fit into equations:
PR(A) = (1-d) + d(PR(t1)/C(t1) + … + PR(tn)/C(tn))
|t1 – tn||pages linking to A|
|C||the number of outbound links that a page has|
|d||damping factor – usually set to 0.85|
More simple way of thinking about it:
a page’s PageRank = 0.15 + 0.85 * (a “share” of the PageRank of every page that links to it)
“Share” is the linking pages’ PageRank divided by the number of outbound links.
