Big networks like ShareASale or CJ Affiliate do not have everything. For digital products like online courses, software tools, or ebooks, many creators run their own affiliate programs directly from their website. A simple way to find them is to search the product name plus the word "affiliate program" on Google. You can also check the footer of a product's website because many companies put a small link there for affiliates. Joining communities in your niche on forums or Facebook groups also helps because people share programs they are using. Have you tried any of these methods?
