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.
I think so? I mean why would all the gambling websites would go for signature campaign if it didnt work at all. Couple of them would try it, it wouldnt work so they would stop it. It is not only a chance to gain new players but also a way to keep reminding people of yourself.
Why do you think Coca-Cola has ads on TV ? So, you can buy Cola? If you are their consumer you will buy it anyway. No it is to remind you, it is to make you want to buy again.
