If you are talking about Google Page Rank, then it only comes through Back Links and Quality of Your Web Content.
I got my Page Rank 2 within 20 days, this is because...
I created daily 25 links and wrote 3 articles (scheduled to be published every 4 hours).
I am targetting Page Rank 6 (thats the highest we can get) within 1 year
So, Start Building some links and put some content on your website...
