From what I determine, Pr is given based on quality back-links and page content. I'm looking to build a higher Pr on one of my domains; the domain has been about for 3 weeks and is currently Pr2. I have done a low blast with ScrapeBox to build backlinks, which is where I think the Pr2 has come from. Is it just a matter of further back linking or is Pr down to are there many other aspects that are taken into account, to determine Pr? Thanks.
