Many people use Medium to write about online business and tools they test. Because of that, affiliate links come up in many discussions. Medium allows them, but the post must still teach something useful and not look like a simple advert.

Writers often explain how a tool works, share results, then place the link inside the article where it fits the topic. Does using affiliate links this way sound acceptable on Medium?
