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.
Yes it really works especially when the design is really attracting and colorful. When a gambler sees the design, for sure he will remember it when he wants to choose a gambling site. It's not a waste of money, that's how advertising and marketing works, just to raise your visibility in the market and that's how signature campaign works.
