Just wanted to jump in and mention that a number of US affiliates with US traffic are working with non-gaming programs and have successfully diversified their traffic.
They’re making a pretty penny too. 
We’re talking retail, lead-gen and the soft game affiliate programs.
Income Access’ sister network Share Results works with some great programs ideal for poker and skill gaming affiliates looking to get more value out of their US traffic. WSOP Academy and Real Arcade are a few standouts.
