Question : I need some urgent help and advice. I have a site that has been a PR5 for several months as a result of a links building campaign that I have been successfully running. Since I understand the importance of getting quality links, I have carefully selected only good partners, avoiding link farms and nothing networks. Recently, I was shocked to notice that my site's home page shows a PR0. It seems that it has been penalized for some reason. I get a feeling that one of my competitors may have caused this to happen by submitting my site to nothing networks or link farms or just spam - submitted my site to Google. How can I get my site's PR restored?
