Hi, I have a competitor that is using ping backs to get ranked. His entire website has gained authority by junk links. The company is creating thousands of nofollow backlinks using what appears to be a ping back. First, how does one create a pingback backlink without actually posting a link the site that you are trying to get a link to, because that appears to be the case for my competitor? Is that possible? Second, is Google really ok with gaining authority in this way? It seems like that would be easy to detect.
