Obtain quality dofollow backlinks from sites with PR... there are many services offering this kind of project. WebDev
PR increase not only depend on "fully based on the quality back links" , it also depend some other strategies like ...... unique traffic from all over the world (you may got unique traffic through social media networks) and regular update the site by latest, unique and copyscape passed 350+words Articles.
by using proper ping-backs and back-links also by using a speedy server will boost pr along with unique content.
I’ve had my own cases where I’ve seen the PR drop and rise with little to no effect on search traffic. One thing to keep in mind though is that the public Page Rank is a little different from the internal Page Rank that Google uses and does matter. The PR we see in our toolbars (and on PR checking sites), is really a moment in time. Google is constantly updating their internal PR (not just every 3 months or so), so what we see might not reflect exactly the PR Google is using. Having said that, it is a nice confirmation that we’re on the right track. And as with most things in life, networking is one of the most powerful tools for success. It’s partly why commenting was the first thing on our list.
You can increase the rank of website by SEO.SEO is good for increase the rank and traffic on website.
Easiest way I know to build PR is post blog comments & guest posting on high pr blog pages. Also, buying a sidebar link will help.
