PR is calculated through backlinks, so that means that you need to get more backlinks.

Backlinks from RELATED, REPUTABLE, NOT PENALIZED sites

look here.

I am confused with your question, you asked how to increase a pr but you said your site is #3. Does this means that the ranking of your site is #3 of the pr of your site is pr3? BTW, to increase your site pr, you need to gather more backlinks. Much better if you can get backlinks with high pr already.
