I have a blog, it has already been indexed by google. But the Pr is still N/A. So I think from N/A to Pr 0 is update.
Oh cool, so within a few hours we will have two or three threads about a new PR update and 100 people asking why their site is not doing better.
Now you are in the official search engine of Google because you already have a PR0 rank . It is much better for you to increase your backlinks coz chances are your PR ranking will surely improve in the next update if you do it
means you have get some backlinks,and if you do more your pr will be increased,and if you build links with some keyword, maybe you have a good rank on search engines.
It probably means you just get indexed.. Or there are some backlinks indexed by Google for your site which are NOT enough to make it a PR1
In my opinion, page rank 0 can mean a penalized website or you didnt have enough backlinks to get a higher value.
PR 0 means your website is cached with the google and index...............while not ranked means your website has crawled by google and index..................
