My website (2.5 months old) : www.creditcardpaymentgateways.in was showing PR as 0 all along. Three days back I observed that the PR is N/A now. Can somebody tell me the reason? Anurag
so there is duplicate content on your site... I wouldn't expect to build a high PR with duplicate content so perhaps this is the reason... The point about your backlink profile is true as well... Links from websites which also have n/a Page Rank can be quite risky... Look to link from trusted, reputable sources only and you shouldn't go to far wrong...
Your website got indexed for 172 pages in Google so the duplication issue has nothing to do with your pagerank. You should glad since this a PR changing and could be anywhere from 0 - 10. However, since your website has zero backlinks in Google then you should not over expecting a high pr this time. You may consider check back any link strategy you applied and see if some of them might be looking suspicious from Google pint of view.
Just wait few days , pr 0 is the lowest pr you can have. N/A means you didnt got updated yet to a certain pr.
Do you put many links (other website) at your website ? Perhaps you're recommended many web PR 0, then Google downgrade your website. Or your website down very often, block google bot, then Google can't give you any PR anymore.
