Review Brigades

Brigading is a term used when online trolls group together to flood another site (or subsection of a website) with their message.  On Amazon, this happens when a product is quickly flooded with negative reviews, often politically motivated, and likely by reviewers who have not actually used the product or read the book. We’ve seen […]


Amazon Vine: An Analysis of 30 Million Reviews Shows Vine Better than Incentivized

  On September 19th, 2016, we published a video showing that Incentivized Reviews (reviews including a disclaimer “I received this product for free or at a discount in exchange for my honest, unbiased review”) were highly biased, which quickly went viral, racking up over half a million views. Two weeks later, on October 3rd, 2016, […]


Amazon’s New Privacy Settings Enable Reviewers to Hide their Dishonest Reviews

One of our core beliefs here at ReviewMeta is transparency.  We feel that making more information available will help the consumer, while deliberately hiding information will have the inverse effect.

A Follow-Up to Our Incentivized Reviews Video: Answers to Your Questions

  We didn’t expect our video from last week to hit half a million views so quickly.  It just goes to show you how upset consumers were about this massive problem of incentivized reviews.  The success of the video generated a TON of comments and questions, so we made a follow-up video to address them. […]


Amazon Bans Incentivized Reviews – Was it Because of our Video? Does ReviewMeta still work?

If you haven’t already heard, Amazon has banned “Incentivized Reviews”:   Was this because our video went viral a few weeks ago? The answer is NO.  This decision likely has NOTHING to do with our video or ReviewMeta in any way.  We have never posted an incentivized review to Amazon; we have simply exposed that the […]
