The story starts from 2011 when my blog was getting a good traffic (400UV per day). Then Google went crazy and rolled out those Penguin and Panda and other algorithm updates. Ever since that time I have a steady decline in traffic and now I hardly have 5UV per day. Before I was hit my blog was PR2 and went back to PR0 in subsequent update. However in latest update (about a month ago) I got some PR back and now its PR1. Even though my PR is half back my traffic is the same. No improvement in ranking whatsoever. I have never received any message in my webmaster tool so its not manual action. My links were mostly made by commenting like everyone else back in 2011. This was a kind of overview but my real question is should I try to recover my site or just buy a new domain and start over again. I have more than 250 post on this blog and I just can't leave it. Can I use these posts in new domain I purchase or will I get another penalty for using the content. I am tired of trying to recover this site and at this point I think its just a waste of my time and effort. What do you guys think I should do. Waiting for your suggestion.
