You get paid for referring those who buy games or keys for games. This is not a one time commission either. Everybody who makes a purchase thanks to your recommendation is added to your “team” or referral network. And each order made by that person within the future also brings you a profit. Promote games on your blog/website. It hasn't to be games related. If you have blog about MMA for example, you can advertise UFC game, if you own website about planes, you can sell flight simulators, if you have blog about trucks, you can sell truck simulator games etc
