My blog Full Version Software Downloads has recently got PR 2 from 0. What is the criteria for obtaining PR from google?
The Criteria of Allocating Page Rank to a particular blog is unique and fresh content as well as qualitative back links!!
It counts number of quality back links, traffic on blog/website and how frequently you update your blog with quality content.
Well mostly it is backlinks but it has appeared these days that sites with no backlink and only unique content also get some PR.
