A rakeback is a promotional technique that some casinos use to give a portion of their house “rake” back to that player, usually for a limited period of time. Rakebacks are a good promotional method for affiliates because usually the program will still provide some or all of the commissions due to that affiliate simply for the ability to earn that customer. If you're working on a RevShare basis, it may be valuable to choose rakeback programs because your players will keep more of their money and may play with that casino for longer.
