Analysis Details
Fail Suspicious Reviewers
One-Hit Wonders
41 of the 2,160 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 3.0 while the reviewers who have posted more than one review have rated this product an average of 4.1. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Never-Verified Reviewers
40 of the 2,160 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 3.4 while the reviewers who have written at least one verified purchase review rated this product an average of 4.1. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Take-Back Reviewers
707 of the 2,160 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, the discrepancy in ratings between the Take-Back Reviewers and reviewers who don't have any deleted reviews in their history isn't significant enough to rule out the possibility of it being due to random chance.
Fail Word Count Comparison
-
- 41%
- Have an overrepresented word count
In the graph above, we can see the distribution of review word counts for this product and the expected distribution for this category. We see the following 1 group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 881 reviews (or 41%) are within an overrepresented word count group. These reviews have rated this product an average of 4.4, while all other reviews have rated this product an average of 3.8. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Warn Rating Trend
-
- 52%
- Created over 57 days
We counted 2,160 reviews for this product over the span of 434 days, an average of 5.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 14 or fewer reviews on any given day.
However, we see the following 57 days exceeding this threshold:In total, we found that 1,123 reviews were created on just 57 days. This is an excessively high number of reviews submitted on these high volume days.
Warn Reviewer Participation
-
- 35%
- From reviewers with an overrepresented participation
We see the following 1 participation group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 749 reviewers (or 35%) are within an overrepresented participation group. While this is more reviews from overrepresented participation groups than we'd expect to see, the discrepancy in ratings between reviewers in an overrepresented participation groups and all other reviewers isn’t significant enough to rule out the possibility of it being due to random chance.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
