A fake review is one written by someone who never used the product, was paid or given free stuff to write it, or was created by a business insider pretending to be an outside customer. This practice is often called astroturfing, because it makes a manufactured opinion look like genuine grassroots feedback. You spot fake reviews by watching for sudden bursts of similar-sounding reviews, checking a reviewer’s history for a pattern of one-note praise across unrelated products, and reading the FTC’s official guidance before trusting a five-star page at face value.
This is not just a matter of good manners online. The Federal Trade Commission finalized a rule called the Rule on the Use of Consumer Reviews and Testimonials, which took effect in October 2024. It makes it illegal for a business to write, buy, sell, or procure fake reviews, to use insiders to post reviews without disclosing the connection, or to suppress negative reviews while claiming its review page reflects all customer feedback. The FTC can pursue civil penalties against companies that knowingly break these rules.
Warning Signs to Check First
Before you trust a product’s star rating, scan for these red flags:
- A sudden spike in reviews posted within days of each other, especially right after a product launches or after bad press
- Repeated phrases or sentence structures across multiple “different” reviewers
- Reviewer profiles with only one review ever, or accounts that only review products in one narrow, unrelated niche
- Reviews that read like ad copy, listing every feature instead of describing actual use
- An unnatural split between almost all five-star and almost all one-star reviews, with little in between
- Missing “verified purchase” labels on a large share of the positive reviews
Common Fake Review Tactics
Incentivized Reviews
A company offers a discount, free product, or gift card in exchange for a review. This isn’t automatically illegal, but the reviewer must clearly disclose that they were compensated. When that disclosure is missing, it violates FTC guidance on endorsements.
Review Farms
Some operations run networks of fake or paid accounts that post glowing reviews across many unrelated products for a fee. These accounts often share writing patterns, post in bursts, and have thin purchase histories.
Competitor Sabotage
Instead of boosting their own ratings, some bad actors post fake negative reviews on a rival’s listing to drag down its average score. If you run a business and see a wave of one-star reviews with no purchase history and vague or contradictory complaints, this may be what’s happening.
Review Hijacking
A seller changes the product listed on an established, well-reviewed page to a completely different item, inheriting reviews that have nothing to do with what’s actually being sold.
How to Analyze Reviews Before You Buy
- Read the three-star reviews first. Middle-of-the-road reviews tend to be more balanced and specific than the extremes.
- Check the review timeline. A steady trickle of reviews over months looks more organic than a cluster posted in a single week.
- Look at reviewer history. Click on a few reviewer profiles. A real customer usually has reviews across different kinds of products over time.
- Compare across platforms. If a product is sold on more than one site, check whether the ratings and complaints line up or look wildly different.
- Watch for specificity. Genuine reviews usually mention a particular use case, a flaw, or a detail. Vague praise with no specifics is a weaker signal.
How to Report Fake Reviews
- Report it directly to the platform where it appears, such as Amazon, Google, Walmart, or Yelp
- File a report with the FTC at ReportFraud.ftc.gov and include the words “fake review” in the comments field
- If the platform doesn’t act and you believe a business is breaking the law, you can also use the USA.gov consumer complaint guide to find the right state or federal agency
Extra Caution Groups
Take extra time before relying on reviews for big-ticket purchases like home repair contractors, medical devices, or financial services, where a bad decision costs more than a few dollars. Older adults and first-time online shoppers are more likely to be targeted by review farms selling to unfamiliar or newly listed sellers, so a second opinion from someone you trust is worth the extra step before buying.
Frequently Asked Questions
Is it illegal for a company to buy fake reviews?
Yes. Under the FTC’s Rule on the Use of Consumer Reviews and Testimonials, businesses are prohibited from writing, buying, selling, or knowingly using fake reviews, and the FTC can pursue civil penalties against violators.
How can I tell if a review was written by a review farm?
Look for accounts with only one review ever, reviews posted in a tight burst, repeated phrasing across “different” reviewers, and a reviewer history limited to one narrow, unrelated product category.
Are reviews in exchange for a discount always fake?
Not automatically. They’re allowed if the reviewer clearly discloses they received something in exchange for the review. The problem is when that compensation is hidden.
What should I do if a competitor is posting fake negative reviews about my business?
Report the reviews to the platform where they appear and file a complaint with the FTC at ReportFraud.ftc.gov. Keep screenshots and any evidence the reviewer never purchased from you.
