Cpa sucks for casinos. BUT for Poker it’s not a bad idea due to Rakeback.
When Rakeback really caught on I saw my affiliate earnings plunge by 60 percent over the course of three months. I always target high rollers and as a result I had a higher percentage of targeted players. I have since decided to refocus my efforts more on Casinos and demphasize poker until this rakeback issue gets cleared up.
