How to Spot Fake Amazon Reviews: 9 Checks That Still Work in 2026

Fake reviews are no longer easy to spot by eye. Researchers commissioned by the UK government estimated that 11% to 15% of reviews in consumer electronics, home and kitchen, and sports and outdoors were fake across nine UK e-commerce platforms (UK Department for Business and Trade, 2023). Amazon says it blocked more than 275 million suspected fake reviews in 2024 alone (Amazon). Plenty still get through.

The good news: fake reviews leave patterns. Here are nine checks that work, roughly in the order you should do them.

1. Sort by "Most Recent" and Look for Bursts

What to look for: a cluster of 5-star reviews posted within a few days, especially soon after a product launches or after a long quiet stretch.

Why it works: Paid review campaigns are bought in batches. In a widely cited academic study of the fake review market, products that bought reviews saw a significant but short-term rise in their rating and review count (He, Hollenbeck and Proserpio, Marketing Science, 2022). Bursts are the footprint of that purchase.

2. Compare Recent Ratings With the Overall Average

What to look for: an overall average of 4.6 stars, but a run of 1- and 2-star reviews in the last few weeks.

Why it works: The same study found that once sellers stopped buying reviews, average ratings fell and the share of one-star reviews rose, especially for newer products (paper). Recent reviews show you what happens after the campaign ends.

3. Read the 2-, 3- and 4-Star Reviews

What to look for: specific, checkable complaints: "the strap broke after two weeks," "runs a size small," "the app needs an account."

Why it works: Paid campaigns mostly target 5-star reviews, and sometimes 1-star reviews of competitors, so the middle is often more informative. It's where owners tend to explain trade-offs. If a product has thousands of ratings but almost no 2–4 star reviews with real detail, be careful.

4. Check That the Reviews Describe This Exact Product

What to look for: reviews that mention a different color, size, flavor, or a different product entirely; or a listing whose oldest reviews are years older than the product looks.

Why it works: This is review hijacking. The FTC's first case on it, against supplement maker The Bountiful Company, alleged that new products were attached to older listings so they inherited reviews, higher ratings and even "#1 Best Seller" and "Amazon's Choice" badges. The company paid $600,000 (FTC). Look at the variant label printed above each review and the "Date First Available" in the product details:

• Check the variation label shown above each review (such as size or color) to see which version it was written for.
• Compare the dates of the oldest reviews with "Date First Available" in the product details. Reviews older than the listing suggest they came from another product.

5. Open a Few Reviewer Profiles

What to look for: accounts that only post 5-star reviews, review dozens of unrelated products in a short window, or have reviewed the same seller's products repeatedly.

Why it works: A reviewer's history tells you more than any single review (Reviewed, 2026). Real shoppers leave mixed ratings over time.

6. Be Suspicious of Generic, Polished Praise

What to look for: reviews that could apply to any product ("great quality, exactly as described, highly recommend"), repeated phrases across different reviewers, or tidy pros-and-cons layouts that never mention actually using the item.

Why it works: Templated and AI-written reviews tend to be fluent but vague. An AI-detection study of about 30,000 front-page reviews on 500 Amazon bestsellers flagged roughly 3% as AI-generated with high confidence, and 74% of those gave 5 stars versus 59% of human-written reviews (Pangram Labs, 2026, a detection vendor).

7. Don't Treat "Verified Purchase" as Proof

What to look for: nothing specific; just don't let the badge end your investigation.

Why it works: In a brushing scam, a seller ships an item you never ordered so it can post a fake review in your name, according to the FTC. Refund-for-review schemes also produce real purchases. In the Pangram study, 93% of the AI-generated front-page reviews carried the Verified Purchase badge.

Here's why Verified Purchase isn't proof, and how bought reviews get the badge.

8. Look at the Seller and the Brand

What to look for: an unfamiliar brand with thousands of near-perfect ratings in a short time, a storefront where every product scores 4.8 stars, or a card in the box offering a gift card or refund for a 5-star review.

Why it works: Offering rewards for positive reviews is banned under the FTC's fake review rule, in effect since October 21, 2024. Sellers who break it on one product often do it across their catalog.

Badges don't settle it either: Amazon's Choice doesn't check whether reviews are genuine.

9. Run the Link Through a Review Checker

What to look for: a second opinion that reads many reviews at once.

Why it works: Review bursts, near-identical wording and text copied from other products are hard to see one review at a time. Paste the product link into FakeFind's free Amazon review checker. It checks the reviews for warning signs and returns a Trust Score (1–10) and the FakeFind Rating: Amazon's stars with the suspicious reviews discounted. Then use checks 3 and 4 above to judge the product itself.

How to Read a FakeFind Result

The FakeFind Rating matters as much as the score. If a 4.7-star product drops to 3.9 once suspicious reviews are discounted, that gap is the story. The Trust Score rates the reviews, not the product. Full details: how FakeFind works.

What to Do if You Find Fake Reviews

• Report the review to Amazon using the "Report" link under it.
• Report reward-for-review inserts or unordered packages to the FTC at ReportFraud.ftc.gov.
• Use your return window if a product doesn't match its reviews, and leave an honest review of your own.
