The thing with affiliate marketing is you have to sell products that offer a monthly recurring revenue source, not a one time purchase as in the days of old. Today, it’s best to be affiliated with an online software such TubeBuddy (I do Uscreen as I specialize in that) which will pay out monthly. Subscriptions are in. Single purchases are yesterday’s news (I’m capping because I still sell single purchase digital items. But I’m shifting).
