By Fake Review Detector
A fake review is any review written to mislead shoppers rather than to share a genuine experience with a product, service or business. It can be a glowing five-star review bought for a few dollars, a one-star attack paid for by a rival, or a review written by software that never used the product at all. If the writer did not honestly use what they are reviewing, the review is fake — no matter how real it sounds.
That simple test matters more in 2026 than ever. Fake reviews now sit on almost every platform shoppers use: Amazon.com and Amazon.co.uk, Google, Trustpilot, Etsy, eBay, Booking.com and TripAdvisor. Regulators on both sides of the Atlantic have started to treat them as what they are — a form of deception. The US Federal Trade Commission's rule banning fake reviews and testimonials took effect in October 2024, and in the EU, fake reviews have been banned under the Consumer Omnibus Directive since May 2022. Knowing the seven types below is the fastest way to protect your money.
What Counts as a Fake Review?
A review is fake when it misrepresents the reviewer's experience. That covers more than invented praise. A review is fake if the writer was paid to write it without disclosing the payment, if it was written by a bot or AI tool, if it describes a product the writer never bought, if it was written by the seller, their staff or their family, or if it was posted to damage a competitor. Even a review that is technically true can be fake in effect: when a seller only asks happy customers to leave reviews and hides the unhappy ones, the star rating you see is a distorted picture.
The opposite is also true. A negative review from a real customer who had a bad experience is not fake, however harsh it is. The dividing line is honesty of experience, not positivity. That is why spotting fakes means looking at patterns — who wrote it, when, and what it actually says — rather than trusting any single star rating.
Type 1: Paid Five-Star Reviews
The most common type of fake review is the paid five-star review. A seller pays a person, or a small network of people, to write glowing reviews for a product they may never have used. Payment is often a full refund of the purchase price, a free product, a gift card of $5 to $20, or a small cash fee per review. The reviewer buys the product, leaves five stars, and gets the money back — so the review looks like a verified purchase.
These reviews are easy to recognise once you know the pattern. They arrive in clusters: ten or twenty five-star reviews in a few days on a product that had almost none before. The wording is vague and interchangeable — "great product, highly recommend, fast shipping" — with no detail about how the product was actually used. The reviewer's profile often shows a history of reviewing unrelated products in the same style, sometimes dozens in a single week. On Amazon this violates the platform's rules, and under the FTC's 2024 rule buying or selling fake reviews is illegal in the United States; in the UK and EU the same practice breaches consumer-protection law.
Type 2: AI-Generated Reviews
AI-written reviews are the fastest-growing type of fake review. Anyone can now ask a chatbot to produce fifty convincing five-star reviews in a minute, each with a different name, tone and supposed use case. These reviews are cheap, instant and hard to spot, because the language is often polished and grammatically clean.
The giveaway is usually sameness hiding behind variety. AI reviews tend to repeat the same structure: a short enthusiastic opening, two or three generic benefits, and a recommendation to buy. They praise features in the exact words of the product listing rather than in the messy language of a real user, and they rarely mention a specific problem, a surprise, or a comparison with a previous product.

Type 3: Bot and Review-Farm Reviews
Review farms are organised operations that produce fake reviews at industrial scale. A farm may run hundreds of accounts, each with a plausible name and photo, posting reviews on demand for whichever seller pays. Bots automate the process further, generating and posting reviews without any human involvement at all.
The signs are scale and repetition. The same phrases appear across many reviews for the same product — "amazing quality for the price", "exceeded my expectations", "will buy again" — word for word. Reviewer accounts have thin histories: an account created last month that has reviewed twenty products in three unrelated categories. Posting times cluster oddly, with dozens of reviews appearing overnight or on the same day. A real product earns reviews gradually, spread over weeks and months as people buy and use it. A farm's work arrives in waves.
Type 4: Fake Negative Reviews and Review Extortion
Not every fake review is positive. Fake negative reviews are written to damage a business, and they are just as dishonest. A competitor pays for one-star reviews on a rival's listing. A disgruntled ex-employee posts several bad reviews from different accounts. Or a stranger demands a refund or a free product and threatens a flood of one-star reviews if the seller refuses — a practice known as review extortion.
These attacks are particularly common on Google Business Profiles, Trustpilot and Etsy, where a handful of one-star reviews can push a small business down the search results. The reviews themselves often give themselves away: they describe a product or service in terms too vague to match a real transaction, they never mention a specific order, date or interaction, and several of them appear within hours of each other. For a business, the damage is real even when the reviews are fake, which is why platforms have reporting and removal processes for them — and why shoppers should be sceptical of a sudden burst of one-star reviews, just as they are of a sudden burst of five-star ones.
Type 5: Cherry-Picked and Gated Reviews
Review gating is the quietest form of fakery, because no single review in the set is invented. The seller simply controls who gets asked. After a purchase, only customers who gave a high score in a private feedback survey are invited to leave a public review; unhappy customers are routed to customer service instead. The result is a five-star average built on a filtered sample — every review is real, but the rating is a lie.
You can spot gating by reading the distribution, not the average. A product with 400 reviews and 98 percent five stars, with almost no three- or four-star reviews at all, is suspicious: real products earn a spread of opinions. In the EU, review gating is caught by the Omnibus Directive's ban on misleading review practices, and in the US the FTC's 2024 rule prohibits misrepresenting that reviews reflect the experience of ordinary customers when they do not.
Type 6: Reviews for the Wrong Product
Some fake reviews are not written for the product you are looking at at all. Sellers hijack the reviews of a different, well-rated product by merging listings or reusing an old product page for a new item. A phone case inherits the glowing reviews of a popular phone charger. A cheap kitchen gadget carries the five-star history of a bestselling blender. The stars are real reviews — for something else entirely.
The clue is in the text. Read the reviews, not just the stars: reviewers mention a different product name, a different colour, a feature this product does not have, or a price far from the current one. On Amazon, check the review dates against the product's launch date — reviews dated years before the product existed belong to whatever the listing used to be. This type is common in categories where sellers recycle listings, and it is one of the easiest fakes to catch, because the reviews contradict the product page in plain sight.
Type 7: Self-Reviews, Staff and Family Reviews
The last type is the oldest: reviews written by the seller, their employees, their friends or their family. The business owner leaves five stars for their own restaurant. Staff are asked to review the company they work for. A seller's relatives post praise for a product they received for free. These reviews are rarely disclosed, and they are written by people with a direct financial interest in the rating.
They tend to read like marketing copy rather than customer experience — long on superlatives, short on specifics, and full of the business's own selling points. A restaurant review that praises "our commitment to quality" is not written by a customer. A product review that lists every feature in the order they appear on the packaging was written by someone with the box in front of them, not by someone who used the product. Under both US and EU law, undisclosed self-reviews are deceptive, and most platforms ban them outright.
How to Check a Review You Do Not Trust
Definitions only take you so far — the next step is to test a suspicious review before you act on it. Copy the review text and paste the review text into our fake review checker: it analyses the language patterns, repetition and structure and gives you a verdict in seconds. Do the same for a couple of other reviews on the same listing; if several come back suspicious, treat the whole star rating as unreliable and shop elsewhere. For the full step-by-step detection routine, read our flagship guide on how to spot fake reviews — it walks through the two-minute check we recommend before every purchase.
Frequently Asked Questions
What is a fake review?
A fake review is any review written to mislead shoppers rather than to share a genuine experience. The writer may have been paid, may never have used the product, may be the seller or a rival, or may be software rather than a person. The common thread is that the review does not reflect an honest customer's experience.
Are fake reviews illegal?
Yes, in both the US and the EU. The FTC's rule banning fake reviews and testimonials took effect in the United States in October 2024, and the EU's Consumer Omnibus Directive has banned fake reviews since May 2022. Platforms also prohibit them in their own terms, and sellers caught buying reviews risk fines, account suspension and removal of their listings.
How common are fake reviews?
No platform publishes an exact figure, and any precise percentage you see quoted without a source should be treated with suspicion. What is certain is that fake reviews are a large, organised industry: review farms, paid-review groups and AI tools operate openly, and they target the biggest marketplaces — Amazon, Google, Trustpilot, Etsy and Booking.com — because that is where shoppers look first.
Can AI detect fake reviews?
Automated tools can flag suspicious patterns — repeated phrasing, unnatural structure, clustered posting dates, thin reviewer histories — but no tool is perfect, and the best results come from combining a tool with your own reading of the reviews. Paste the review text into our fake review checker for an instant language-based verdict, then check the reviewer's profile and the review dates yourself.
What should I do if I spot a fake review?
Report it on the platform where you found it — Amazon, Google, Trustpilot and Etsy all have a report option on every review. Do not buy based on it, and warn others by leaving an honest review of your own if you have genuinely used the product. If a seller offered you money or a free product in exchange for a five-star review, report the seller too: that offer is itself against platform rules and, in the US and EU, against the law.
What to Do Next
The next time a product's reviews look too good — or a business's look suspiciously bad — stop and test them. Open the listing, read five reviews in full instead of trusting the star average, and paste the review text into our fake review checker before you spend a dollar or a euro. Spotting the seven types in this guide takes a minute, and it is the cheapest insurance you will ever buy against a bad purchase. Start with the review you were about to trust.
