Review bombing on Amazon: how sellers are fighting back against fake 1-star attacks

Review bombing is a persistent dirty trick on Amazon, and one coordinated burst of fake 1-star ratings can drag a listing under the 4-star line. That threshold matters more than many sellers realize: large numbers of buyers filter search results to show only products rated 4 stars and up, so dipping below the line can make a listing effectively disappear, along with the repeat customers and future positive reviews those lost sales would have produced.

Even established brands are targets. The chief executive of one supplements brand with more than a decade on Amazon saw a stream of clearly sabotage reviews roll in from non-customers before turning to a review-auditing service for help.

Specialist services now scan listings, flag coordinated attacks and pursue removal of fake reviews through Amazon's own terms-of-service channels. In the supplements case, the brand reports its conversion rate recovered, retention improved and its reputation got back on track after the fraudulent reviews were taken down. Sellers are advised to monitor ratings continuously rather than discover an attack after the ranking damage is done.
