What is a verified review, and why is it not the whole story?

A verified review usually signals purchase context, but teams should also look at recency, usefulness, detail, and whether the feedback reflects the current product experience.

Why supplement reviews can be harder to earn and interpret

Supplement reviews can be harder to earn and interpret because customer experience is personal, delayed, and often shaped by expectations.

Why review quality matters, not just review count

Review count matters, but useful customer reviews do more than add volume. They support ratings, shopper confidence, discoverability, and product feedback.

Amazon connects high-quality reviews with sales, discoverability, and product insight. The broader lesson for marketplace teams is that review quality matters because useful customer feedback helps shoppers decide, gives Amazon more customer language to surface, and shows where products are creating trust or friction.
