More than just Fake Reviews: Why detects all types of bias

At, we scan hundreds of millions of reviews and help you sort out the trustworthy ones from those that might not be completely honest.  The average consumer might mistakenly label anything that looks suspicious as a fake review, however textbook fake reviews are only a subset of the overall problem of biased reviews. First, […]


Somehow 97.4% of Products on are rated Above Average

In 4th grade, most children in the United States are taught how to calculate averages.  Seems someone at skipped ahead that year.  When it comes to product ratings, their notion of “average” is way off. We noticed that every product on has a rating accompanied by a single-word description just below it.  The […]

Two weeks later, on October 3rd, 2016, […]

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. For example, being able to see a reviewer’s full history is necessary to get a feel for their trustworthiness.  If they give EVERYTHING a glowing 5-star review, […]

This week, Amazon continues to make changes to their review platform, but this time […]
