Hello, I have a simple website where people are guessing sports results and winning prizes. I am thinking of running a simple affiliate system. But i am not sure what prices should i set. The website has no income and it is not selling any product. I am willing to pay only for active visitor (for example who is actively participating for about a month) and not for simple clicks. So, can anyone help me calculate the average price that should be paid for the advertiser so that both sides were happy?
