There are many lucrative offers for mobile out there, and some accept incent traffic. What is incent traffic? That is when people get paid money, a prize, or some kind of reward to do something, ie play a game, install an app, fill out a survey or whatever.
Anyway, most affiliates keep this on the down low because its guaranteed cash and profits (Conversion % can be as high as 80% on these), some of these sources are for app developers only, or if you are close to the app developer (aka Exclusive offers)…
NOTE: Most CPA Networks/offers DO NOT ACCEPT Incentive traffic. YOU MUST Talk to your AM – If you run incent on offers you might get your account suspended and all of your generated revenue forfeited. Don’t say I didn’t warn you!
