There should have been an option, all of the above. The first thing I am looking for is security when it comes to me, my payments and earnings. I look around the forums, if the program has affiliates that complain from it and I checkout their terms in agd.
If everything seems all right, I proceed with checking out their bonuses and offers for the players. If everything is all right I give them a shot and now depending on how well they convert my traffic I either decide to stick with them or let them go.
Manager support, emails and general attitude towards me also matters once we have started to do business. I do drop ignorant Ams that take weeks to deliver me a simple gif banner or anything of that sort. I believe that both parties should be putting effort no matter how big or small either is. If you don’t think the affiliate is worth it, just don’t do business with him/her.
