Im in charge of SEO for a site called mywindows7key.com
It has links coming into it from emailmarketingprofessional.com and from product-key.com
I've also submitted it to hundreds of website and article directories and have internal backlinks.
However, it remains a PR0. Is it possible that it is remaining at PR0 because the content is too much like http://www.product-key.com? Does Google penalize for similar (not duplicate) content?
Thanks in advance.
