i have couple of blogs from google blogger. After pr update, i found some of my low profile blogs having less than 10 backlinks( most of them are from my group blogs) got pr1.But the blogs with 200 backlinks got pr0. strange?
The mystery of PR.... Who has any idea. Are any of the 200 links for the PR0 sites 'paid directory' links? Those might be worthless links in Googles eyes.
A big factor is the page rank of the backlinks. Try checking with this free tool: http://www.linkvendor.com/seo-tools/domain-popularity.html
