hi,
i am wondering how much it would be a good budget to test a product from click bank (30 dollars pay out)
The thing with Facebook is there's no minimum budget, it just depends on how fast you want to get results. I'd say starting around $20 a day for each ad copy should get you good data. Increase once you find out what's doing well and what's flopping.
Pro-tip: Give Facebook a couple days to optimize your traffic. Sometimes an ad would start at $0.3 cpc the first day, and 2 days later you'd find it at $0.08 or something. So don't start trimming your ads just yet 
Hey hangman, i tried a CB offer last week and was profitable on day one. Started with 75€ on the first day. Wanna connect? Message me Your Skype!
