Promoting a product is an important part of affiliate marketing, but sometimes the results are not as expected. A product may seem good at first, but later users might report problems, or the company's service may change, making the promotion feel wrong. This can affect trust with readers, because promoting something that does not work well can harm credibility. Has anyone else faced a situation where a product seemed fine at first but later caused regret? How do other marketers choose products carefully to avoid problems, and what are the best ways to handle a product that turns out to be disappointing after promotion?
