Create good and unique content to your blog, and get as many quality backlinks as you can for your site.
Hi, In my own experiences, PR 0 would only mean your blog has been ranked but has no value currently in Google's eyes. If you want to boost your SERP ranking for your targeted keywords, you need to update your blogs with niche relative contents regularly and increase back links using your targeted keywords as anchor text stably via channels like social bookmarking, article submission etc. all the best,
Continue doing what it is you did, and hopefully you should see a steady increase, pagerank takes time
Yeah! Post a high quality and unique content and other people will link to your blog and your page rank will increase. Just don't worry about page rank I was too worried about page rank contact with them. Just waiting for reply!
Yes, it is not so big matter if your page rank changed from NA to 0, it is common! Just try to make your site SEO friendly, try to build link and should have knowledge about SERP!
