A business with 300 five-star reviews looks like a safe choice. But anyone who has booked a "highly rated" hotel that turned out to be nothing like the photos knows that a star rating alone can be misleading. Some reviews are written by the owner's friends. Some are bought in bulk. And some negative reviews are planted by competitors.
The good news: fake reviews usually leave a trail. You don't need special software to spot most of them, just a few minutes and a habit of looking past the average score. This guide walks through the signs we look for when checking listings, what regulators and platforms are now doing about the problem, and how to make a decision when you can't be completely sure.
Why fake reviews are harder to ignore in 2026
Fake reviews are no longer just a nuisance. In several major markets they are now explicitly illegal.
United States: The Federal Trade Commission's rule on consumer reviews and testimonials (16 CFR Part 465) came into force on 21 October 2024. It bans fake reviews, including AI-written reviews that pretend to come from real customers, and buying positive or negative reviews. Penalties can reach $53,088 per violation. In December 2025 the FTC sent warning letters to ten companies, its first public enforcement step under the rule.
United Kingdom: Since 6 April 2025, the Digital Markets, Competition and Consumers Act treats fake reviews and hidden incentivised reviews as banned practices. Fines can reach up to 10% of a company's global turnover, and sites that publish reviews must take reasonable steps to detect and remove fake ones.
Google Maps: When Google finds fake engagement on a Business Profile, it can block new reviews for a period, unpublish existing ones, and show a public notice saying suspected fake reviews were removed.
Stricter rules mean fewer obvious fakes, but they also push the people who write them to be more careful. That is why it helps to know what to look for.
9 signs a review might be fake
1. The language is vague and could describe any business
Real customers mention specifics: the name of the technician who came, how long the wait was, which dish was cold. Fake reviews tend to stay general: "Great service, highly recommend, best in town!" One vague review means nothing. Twenty of them in a row is a pattern.
2. Lots of reviews arrived at the same time
Sort the reviews by newest and look at the dates. A small business that normally gets two or three reviews a month and suddenly receives forty in one week deserves a closer look. Sometimes there's an innocent explanation, such as a grand opening or a request sent to past customers, but bursts are one of the most common signs of bought reviews.
3. The reviewer profiles look empty
On Google Maps and most review sites you can tap a reviewer's name. Be cautious when many reviewers have no profile photo, only one review ever, or a history of five-star reviews for businesses scattered across different countries in the same week.
4. The ratings are only 5 stars or 1 star
Genuine feedback for most businesses spreads across the scale. A listing with almost nothing between one and five stars may have been padded, attacked, or both. Pay most attention to the three- and four-star reviews. They are rarely faked and usually the most balanced.
5. Several reviews repeat the same phrases
Watch for the same unusual wording, the full business name repeated awkwardly ("Best Plumbing Services Karachi did a great job"), or keywords stuffed into sentences. That style usually comes from someone trying to influence search rankings, not from a customer describing their visit.
6. The review doesn't match what the business actually does
A review praising the "delicious breakfast" at a hotel that doesn't serve breakfast, or a dentist reviewed for a service they don't offer, is a strong signal. Cross-check details against the business website or listing.
7. Negative reviews push you toward a competitor
A one-star review that ends with "go to XYZ instead, they're much better" is a classic competitor tactic. Real unhappy customers usually focus on what went wrong, not on advertising someone else.
8. The owner's replies look copied and pasted
Owner responses tell you a lot. A thoughtful reply that addresses a specific complaint is a good sign. Identical "Thank you for your kind words!" replies under dozens of short reviews can suggest the reviews were manufactured as a batch.
9. The platform has already flagged the business
If you see a notice that suspected fake reviews were removed from a listing, take it seriously, but don't treat it as final proof. As tech journalists have pointed out, the notice doesn't say whether the removed reviews were positive or negative, so a business can sometimes be the target rather than the cause.
A 5-minute check before you book, buy, or hire
When the decision involves real money, such as a contractor, a clinic, or a deposit for an event venue, run through this quick routine:
Read the middle. Skip the five-star and one-star reviews at first and read ten three- and four-star reviews.
Sort by newest. Check whether recent reviews match older ones in tone and frequency. A business can change ownership or quality.
Compare platforms. Look up the same business on Google Maps, Facebook, a local directory, and industry sites. A 4.9 on one site and a 2.8 on another tells you something.
Look for photos from customers. Real customer photos are harder to fake than text.
Verify the basics. Confirm the address, phone number and website exist and match across listings. Our guide on how to check if a business is legitimate covers this step in more detail.
What to do if you find a fake review
Most platforms let you report a review you believe is fake. On Google Maps, you can open the review menu and choose to report it. Reporting won't always lead to removal, but it adds a signal the platform can use.
If you're a business owner dealing with fake negative reviews, reply calmly and factually without accusing the reviewer, report the review through the platform, and keep records. Never respond by buying positive reviews to balance it out. That can expose you to platform restrictions and, in some countries, legal penalties. Focus instead on ethical ways to collect genuine reviews from real customers.
Reviews are one signal, not the whole picture
Even honest reviews only tell you how a business treated a handful of people. Combine them with other signals: how long the business has existed, whether it lists a real address, how clearly it explains prices, and how it communicates before you pay. Our checklist of 7 things to check before choosing a local business is a good companion to this guide.

Frequently asked questions
Can AI detect fake reviews?
Platforms like Google use automated systems to filter suspicious reviews, and they catch a large share before they're published. No system is perfect, though, so your own judgement still matters.
Are reviews from friends and family fake?
Under the FTC rule and Google's policies, reviews that hide a close connection to the business, such as reviews from employees or the owner's relatives, can count as deceptive. Customers who happen to be friends should still describe a real experience.
Is it illegal to pay for reviews?
Paying for positive or negative reviews is banned in the US under the FTC rule and in the UK under the DMCC Act. Offering an incentive for honest reviews is treated differently in some places, but in the UK any incentivised review must be clearly disclosed.
Should I avoid a business with a few bad reviews?
Not necessarily. A business with only perfect reviews can be more suspicious than one with a 4.5 rating and a few complaints that the owner answered well. How a business handles problems is often more useful than whether problems ever happened.
