“Bonuses are just an expensive cost of sales that we have to deal with because that’s the way the system works” "Affiliates generally work on revenue share deals. The revenue that is shared is based on: Gross gaming revenue (difference between player wins and losses) Minus bonus costs (the Tier 2 operators, 25-35% of gross gaming revenue) Minus game provider fees (If it’s a casino, the people who provide the slots, etc.) Multiplied by the revenue share percentage agreed. The average revenue share deal would be roughly 35% and as mentioned previously the total cost of affiliate revenue share for an operator is about 25%. Now imagine there’s an operator who does not give out bonuses and converts very well for you. That operator is going to make you 25-35% more income than those other operators pushing bonuses. The catch, of course, is, that players expect free money – and every player who wants free money is taking money from you as an affiliate." Full article by Nick Garner could be found on this link.
