After going through all your amateurish comments I have one thing to say "Well Tried".Now, the point: i.e The PageRank of a website depends mainly on the quantity of quality backlinks or inbound links that it has from other quality websites.Now what Google considers to be a quality backlink depends on the algorithm that Google uses when making an update for
PR and backlinks.As of the last couple of updates Google made it has made it clear that websites selling links will have their ISP'S BANNED and the ones who are buying the link without their adsense account will not have the link crawled by Google.That's the reason that numerous websites has seen a fall in their
PR and Backlink.
The Page Rank Of A Website depends solely on your inboud links.The PageRank of a website is calculated with the help of the following equation:
PR(A)=(1-d)+(
PR OF LINK PAGE 1*D/NO OF LINKS IN PAGE1)+ (
PR OF LINK PAGE 2*D/NO OF LINKS IN PAGE2)+.....+(
PR OF LINK PAGE P*D/NO OF LINKS IN PAGE P).
Where A,is your website
D is a damping factor =0.85
link page 1,2...,P are the pages that has a link pointing to your website and can be found out by conducting a search on google with link:
www.website.com.
