While working in the poker affiliate industry I have seen every promotion under the sun. WSOP seats, Hummers, cash prizes, Playboy parties, and even a cake.
What do you want to see as an affiliate? Do you think a promotion should rank affiliates by MGR, RMPs, or a completely different form of measurement? We would like to offer a affiliate promotion that is attainable by all of our publishers, small, medium, and large.
I remember that Empire Poker used to run monthly promos awarding the affiliates who achieved a set amount of RMPs in a single month. I know that always got both me and my sub-affiliates out there pushing Empire. In one of those promos I won a cash prize, an Empire chip-set, shirt, hat, poker table top, and Empire branded card decks. I still have most of that gear.
