It is common in affiliate marketing to come across products that look profitable but are not easy to fully understand. For example, some digital tools or software may have many features that are not simple to explain, yet they still have strong commissions. Promoting such items can lead to confusion when customers ask questions that are not easy to answer. Some marketers solve this by testing the product themselves, while others rely only on the company's description. But without a clear understanding, the promotion may sound less authentic, and this could reduce trust. Would it be better to only promote products that are personally tested, or can strong marketing skills replace deep product knowledge? How do most people handle this balance in their campaigns?
