I would ask affiliates who work with both however my opinion is that casino makes more on average. I have heard the player values are higher for casino. If I had to start from scratch I would go with casino because the online casino market is highly competitive and you’ll get more attention from your programs. With larger programs like pokerstars and fulltilt there is less competition so you might not get the same vip treatment as an affiliate. I would only go into poker if I had more of a passion for it and could produce good content and value for those players and market.
