I've been offered a PR7 link I suspect is faked. I tried a pagerank check tool which says "pagerank cannot be confirmed" How accurate are these tools when it comes to detecting fakes? It's a subdomain like blahblah.domain.com and when checking backlinks I only find links leading to the domain.com rather than the subdomain. The offer is a bit too good to be true, so I'm pretty sure this one is a fake, but for future reference has anyone got any tips they would like to share on confirming if a sites pagerank is "real" or not?
