if i was google, I would completely ignore all signatures in all threads. If someone has a link in their signature, that link must belong to whoever is posting it, which means it is useless to google. It is very easy for a G bot to tell what is a signature and what is not. just ignore everything under ____________________________ or look at the source code, I am sure signature has something special about it in the source code. well I am just wondering do signatures still help you in serps, or no?
