The main factors that influence page rank are the backlinks. The anchored text is also importand.

page rank mostly depend on site contents and META ,so you should write META related to your site contents.........and many factor are there but first do it.

There's over 200 factors, about 60 of which are core.. it would take a long time to list them all here.

Well.. There are countless ways to get the PR but the most relevant ways are to get a maximum back links as well as the back links should be from quality sites. The meta tagging and keyword stuffing should be accurate enough. Try to get the reciprocation through the good PR pages of relevance.

Page Rank (PR) is a measure used by Google to determine the importance of a webpage. Contrary to popular belief, Page Rank is unique only to Google. Other search engines do not use PR in any direct way to determine the web page importance. Google Page Rank or PR for short is a ranking system created by Google that assists with their search algorithm. Each website is assigned a value from zero to ten with ten being the highest. When your website is brand new it is automatically assigned a value of zero. Your goal is to get that number up to ten, which isn't easy, but it can be done, it just takes work.

Increased PR makes you rank higher in the organic search results for Google. PR is a lagging mechanism.
