Note my experience is primarily bingo – not casino or poker. I think that bingo definitely is not as lucrative as casinos. Probably similar to or better than recreational poker, but obviously not as good as the pro poker niche. I do alright by bingo, but would expect to make 4 or 5 x as much with a similar position in the casino / blackjack market.
“Whales” are probably about 3 in 100 – and are munchkins compared to what I’ve heard about casino and poker whales – but bingo whales can stick with a site for years.
Same problems with affiliate manager service and slow or erratic payments as the other industries. Don’t put all your effort into one affiliate program – they can go south in a hurry. Do not do CPA. If you want do CPA try something like the credit industry.
