With countless products available on Amazon’s marketplace, online shopping can often leave customers overwhelmed, exhausted, and reliant on product reviews to determine the best purchase.
However, shady sellers have been quick to take advantage of this, and crowd their reviews with fake five star ratings.
But just how many product reviews are fraudulent? To find out, Scams.info analysed ratings for Amazon bestsellers to uncover which products have the biggest boost by fake reviews.

| Rank | Category | Percentage of fake reviews |
| 1 | Books | 37.2% |
| 2 | Baby | 34.8% |
| 3 | Large Appliances | 33.6% |
| 4 | Computers & Accessories | 32.1% |

Book reviews are the most untrustworthy on Amazon. Almost 2 in 5 (37.2%) book ratings are fraudulent, the most of any product category. After analysing Amazon’s bestsellers, the experts uncovered that for 59% of products, over 40% of ratings were fake. For 1 in 20 books, over 90% of ratings were illegitimate.
Shockingly, baby products also receive an extreme amount of fake reviews. Over a third (34.8%) of ratings on Amazon’s baby range are artificial, and one in 16 products had 90% of reviews determined to be fake. Reviews for high-value items like Large Appliances and Computers & Accessories are also untrustworthy, at 33.6% and 32.1% fake rating respectively.
