“This is due to the fact that the first purchase made at a casino is heavily incentivised (for example they Purchase $50 and Get 200 credits Free) and therefore leaves the casino with a negative revenue. A player who makes a purchase without needing to be incentivised is a valuable player for both you, the affiliate, and the casino.
The above means that you will be earning commission on players who are actually spending money and not hunting for free bonuses. In addition, you will earn commission on your customer across all casino brands within Belle Rock Gaming at which they play.”
Who else does this? So stop offering incentives. Most of them are BS anyway.
It is rather obvious that you no longer desire to have any affiliates whatsoever, so why not just come out and say it, or just shut down the affiliate program and keep the money?
