I really wonder this. I never clicked a signature ad and am wondering if it works for gambling sites. I need to be enlightened in this topic, because it looks like a waste of money to me.
It's not waste of money. I never click on signature, but I've found lots of gambling sites because i saw site in signature and did some research before i decided to sign up. Signatures actually pointed sites to me.
I also found a number of services and a number of gambling sites because of the banners in the signature campaign and I often consider them as the powerful services because they know how to give success to their site while those services who do not know how to promote or do not have money for promotion then why to rely on them!
