As the leading online retailer in the US and the UK, Amazon sells just about everything. (Like the logo says, from A to Z.) Whether you are shopping online for a cheap portable charger, eco-friendly cleaning supplies, or headphones for your kids, Amazon is likely your first stop. And when it’s time to choose between similar-looking products, most folks rely on user reviews.
The trouble is that many Amazon reviews are fake. Unscrupulous or desperate sellers pay for glowing reviews, and some offer gift cards or free products in exchange for five-star ratings. Occasionally, sellers will even solicit false negative reviews on competing products. It’s tough to identify with certainty what’s real, but you can reduce the risk of being conned when you know the warning signs. We’ve compiled some tips that can help.
Updated July 2025: We’ve updated this article with recent news, including the UK’s CMA crackdown on fake reviews, the adoption of AI summaries, and Fakespot shutting down.
Fake Amazon Reviews
If you are shopping on Amazon, there is a good chance you’ll see some fake reviews. A 2023 UK government report suggested that 11 to 15 percent of consumer electronics reviews on ecommerce platforms were fake. That investigation led to an explicit ban on fake reviews in the UK in April 2025, as part of the Digital Markets, Competition and Consumer Act 2024. But fake reviews are not easy to eradicate.
The majority are positive, extolling the virtues of a product in suspiciously glowing terms. Short five-star reviews are likely intended to game the system by boosting a product’s ranking and visibility. But there are also more subtle attempts to persuade you to buy, where paid reviewers will go into some detail, maybe share photos, and even write something negative alongside many positives. They might score a product four out of five stars, for example, which can be very convincing.
Some sellers engage in paid negative reviews designed to criticize competing products. They are typically one-star reviews that focus on cons and will often mention another product that compares favorably to try to steer you toward it.
Amazon is not the only ecommerce website with a fake review problem. Walmart, Target, and many others have similar issues (the Federal Trade Commission put more than 700 businesses on notice in 2021 and explored a rule that would trigger stiff civil penalties for violators). Most of the tips we discuss here will serve you in general, not just on Amazon.
How Amazon Sellers Get Fake Reviews
Sellers want to increase their sales, and reviews can do that. The reviewers want to earn cash or free products. That’s why the underground market for fake reviews is thriving. There are overseas companies selling blocks of positive reviews, social media groups that organize teams of reviewers, and companies that offer all kinds of incentives to persuade genuine buyers to leave a favorable review. Sellers also provide refunds or other rewards to convince buyers to remove or edit negative reviews. Reply All’s “The Magic Store” episode covers some common scenarios and is a fun listen on the topic.
How Sellers Manipulate Amazon Reviews
Before we dig into the veracity of individual Amazon reviews, there are a couple of dodgy seller techniques to be aware of. Some sellers abuse the variation system, intended to enable them to sell variations of a product (for example, different colors of the same device). Amazon’s variation policy prohibits sellers from adding variations that are “fundamentally different” from the original and that include new versions or models. But it is very easy to find examples of sellers doing exactly that.
Let’s say a seller has a listing with 4,000 positive reviews and an average of 4.5 stars. They can add other products with far fewer, mostly negative, or even no reviews at all as variations, and at a glance it appears as though they have lots of positive reviews. If you find a listing with multiple variations, you have to scroll down to click See more reviews and then select the All formats drop-down to filter the reviews for the specific product you are looking at.
