What Residual Program Would You Promote
From your experience, what has been the best affiliate program to promote that has residual income streams?
The best meaning: Most reliable to the customer you recommended it to and most reliable to the affiliate.
Something of value that is needed by most in a niche and provides the solution.
...And of course, once you recommend it to someone, you get compensated continually as long as they keep using it
At least the top 3 you'd use I'd love to here your opinions
Thanks!
