I bought an expired domain at the start of January and I've backlinked 4 money pages, but there has been very little in Google search. There is 16 pages on the site and I've been backlinking the money pags wit expired web 2.0s. Today I received this email from Google GWT. "As the webmaster of a site that has suffered security issues in the past, we hope that we have made clear that keeping Internet users safe is one of Google’s top priorities. This goal could not be achieved without the vigilance and help of all webmasters. " What shall I do, keep the site or move the content to another site, as the niche is good. I've got another site which is 7 months old and rank a lot better, the content could be switched this site instead if there is a problem with the expired domain.
