Hello, I'm not a poker affiliate, but I've been heavily involved in the poker scene for years and know pretty much everything there is to know about poker affiliates. There are two main ways to getting paid : either A) 25% of the rake that player generates or B) $50 While $50 for getting someone to sign up for something sounds great, the first is ALWAYS the better option. It can be worth tens of thousands of dollars. Of course, the poker affiliate world is pretty crowded, so you need to find your own special angle.
'One problem they do not pay for american players anymore. That was the big market for poker online.' Sure, nothing's perfect. You can still making more money affiliating online poker than you can for pretty much anything else
