ClickBank

ClickBank is an established affiliate network and e-commerce platform with a large community of active sellers and affiliates. Its marketplace exposes your course to thousands of potential promoters, and the platform handles payment processing and affiliate commission settlement.

Good for course creators launching their first affiliate program and wanting immediate access to a distribution network. However, ClickBank's marketplace also means dealing with higher competition and less control over pricing and positioning compared to hosting on your own platform.
