Amazon has already made similar adjustments in many overseas markets. In 2015, the company moved its European affiliate program to a category-based structure, and according to the affiliate management firm GeniusLink, the result was more of a subtle chill than a freeze-out. “There’s definitely some pain as a result of it,” says GeniusLink CEO Jesse Lakes, “but we haven’t had a single client who stopped doing business because of the new payout structure.”
You should also make sure you aren't competing with your own affiliates for eyeballs. Any marketing channels you're using, such as search engines, content sites or e-mail lists, should be off limits to your affiliates. Put marketing restrictions into your affiliate agreement and notify partners immediately. It's your program--you set the rules. Or, if you prefer, you can let your affiliates run the majority of your internet marketing.
