Hello I want to inquire that how to get page rank stuff please tell me in detail or give me link from where i can read i have made a directory for which i need to increase the page rank
The most simple way to gain a page rank is to exchange links with other sites. It's based on the amount of links you have linking to your website. Google doesn't allow people to purchase links to make a profit off of page ranks so don't do it! Doing it will simply not let you get a page rank.
It's not about the visitors because even though you receive 50,000 visitors per month, you can still end up having a PR2. It's about the amount of links that you can get coming to you.
Pagerank comes from inbound links, meaning sites that link to yours. They pass on their pagerank onto you, not all of it, but some of it, the more sites a site links to the less PR it bleds to each link. There are other factors, but this is probably the basicly one to work on.
I'd advice you to read the sticky faq in this forum http://forums.digitalpoint.com/showthread.php?t=204881
