Competitor leaving fake reviews: what to do and your legal options

If you think a competitor is leaving fake reviews on your Google Business Profile, do three things in this order. Save the evidence. Report each review to Google under its competitor and conflict-of-interest rules. Reply briefly without accusing anyone. Legal action is a separate route. It suits a sustained campaign by a rival you can identify, not a single one-star review.

Google decides each review against its own policy and does not take your word for who wrote it. Your job is to turn a suspicion into evidence that Google can check.

What Google’s policy says about competitor reviews

Google’s rules for reviews are in its Maps user-generated content policy. The policy no longer has a separate “Conflict of interest” heading. Competitor reviews are now covered in three sections:

• Fake engagement. Google does not allow users to post “content on a competitor’s place or business to undermine” its reputation. The same section bans content “not based on a real experience” and content posted from several accounts by one person.
• Rating manipulation. This section bans “Content that is based on a conflict of interest.” Google says a conflict may come from current or former employment, a contractual relationship, or professional or personal ties, and gives “industry competitors” and “familial relationships” as examples.
• Misrepresentation. The conflict-of-interest sentence appears again here, beside false or misleading accounts of the quality of a good or service.

A review from a rival who was never your customer can break all three rules at once. When you write a report or an appeal, name the rules the way Google names them: a competitor posting to undermine your reputation (fake engagement) and a conflict of interest (rating manipulation). The Google review policy guide explains every other category.

Google’s report page also says that Google “doesn’t get involved in conflict between businesses and customers.” A competitor is not a customer. That is the fact your evidence has to show. Other platforms have the same rule: Yelp’s content guidelines say people should not review “your peers or competitors in your industry.”

Signs that a competitor wrote the review

Most bad reviews come from real customers. Before you treat a review as an attack, check it against your records. The signs below point to a competitor, from the strongest to the weakest.

One sign proves little. A vague one-star from a new account can come from a real customer who rarely writes reviews. Two or three strong signs together make a case that Google can check: for example, no record of the person, plus a five-star review from the same account for the business down the street.

A competitor review often sits among real complaints. In one case from our own records, 11 Google reviews came down for a two-location auto service shop in the San Diego area. One of them told readers to go to a competitor’s location instead. The other 10 were complaints about prices, online coupons and appointment times. Check each review on its own facts.

What our data says about clusters and local attackers

Owners often read a burst of one-star reviews as an attack. Our data says to be careful with that reading. The figures below are TrustReviews data from the Google profiles we monitor, October 2026. These profiles belong to businesses that came to a removal company, so they are not a random sample of Google.

• Clusters are common. Of 1,304 one- and two-star reviews we saw within 3 days of posting (406 profiles, 15 March to 4 October 2026), 36% landed within 48 hours of another one- or two-star review on the same profile. We have not measured how much clustering chance alone would produce, and busy profiles cluster more by chance. A cluster is a reason to look closer, not proof.
• Negative reviewers are local. Of 21,500 reviewers who left a one- or two-star review on a monitored profile, only 12 left one on more than one client business. In our data, negative reviews do not come from networks that move from business to business. This covers our clients only, so a reviewer who attacks businesses we do not monitor would not show.
• Copied text is rare. Exact duplicate text appears in 0.3% of one-star reviews on monitored profiles. A complaint posted twice word for word is worth noting, but most fake reviews do not repeat.

What this means for you: if a competitor is behind your reviews, the evidence is most likely local. Look for people near you, in your trade, with a public tie to the rival. Build the case on that tie for each reviewer, not on the timing alone. The Google review data study has the full figures and their limits.

Collect the evidence, using public information only

Reviewers edit and delete reviews and make profiles private, often after they see a reply. Save everything before you report or reply.

1. Screenshot each review with the reviewer name, star rating, date and full text visible. Include the browser address bar so the page can be identified.
2. Copy the link to each review. On Google, the share button on a review gives a link to that one review.
3. Open each reviewer’s profile and screenshot their other reviews. Look for five-star reviews of a rival in your trade and area, and note their dates.
4. Search your customer records for each reviewer’s name, email and phone number. Write down the systems and the date range you searched, and that you found no match.
5. Save public pages that tie a reviewer to the competitor: a staff page on their website, a LinkedIn profile, a public social profile, or a state business filing that lists the reviewer as an owner or officer.
6. Write a dated timeline of each review and of anything that happened between you and the rival around those dates.
7. Keep messages or call notes that show intent, such as a threat from the competitor.

How to report competitor reviews on Google

1. Go to your Business Profile, select Read reviews, then select Report next to the review. Choose the reason closest to the rule the review breaks.
2. If one account posted several reviews, report the profile as well. In the Google Maps app, tap Business, then Reviews, then the reviewer’s name. Tap More, then Report, and choose a reason (Google’s report page).
3. Follow each report in the Reviews Management Tool. If Google finds that a review does not break its policy, you can appeal that decision once, and one appeal can cover up to 10 reviews.
4. Put your evidence in the appeal form. Google decides review by review, so give each review its own evidence, even when the reviews share a pattern.

An appeal note that Google can check states facts, names the rule and links to the proof. For example:

• Record search: “We searched our booking system and invoices from January 2024 to today for this name, email and phone number and found no match.”
• Tie to the rival: “On the same day, this account left a five-star review for a competing business 2 miles away. Link: [review link].”
• Public connection: “The reviewer is listed as a manager on the competitor’s website. Link: [page link].”
• The rules: “This breaks the fake engagement rule against posting on a competitor’s business to undermine it, and the conflict-of-interest rule under rating manipulation.”

A refused first report is common, and the appeal is where evidence counts. Google review appeal status, explained covers each status in the Reviews Management Tool. For fake reviews that are not from a competitor, see how to report fake Google reviews. If a former employee wrote the review, see former employee Google reviews.

Reply without accusing anyone

A short reply tells future customers that you have no record of the person. Do not name the competitor or call the reviewer a liar. The FTC Consumer Review Rule bans “a public false accusation” in response to a review, made knowingly or recklessly, in an attempt to get the review removed (16 CFR 465.7). An accusation you cannot prove is also a defamation risk.

More on replies, including the legal limits for medical and legal businesses, is in how to respond to negative reviews.

Can you take legal action against a competitor for fake reviews?

Yes, in some cases. This section is general information, not legal advice. Laws differ by state. If you are thinking about a lawsuit, speak to a business litigation lawyer licensed in your state.

The Lanham Act

The federal Lanham Act lets a business sue over false statements “in commercial advertising or promotion” about another person’s goods, services or commercial activities (15 U.S.C. § 1125(a)). An honest customer review is not advertising. A rival who posts under fake names to steer customers to itself can be. If the claim succeeds, the court can award the competitor’s profits, your damages and the costs of the case, and can raise the damages to up to three times the actual amount (15 U.S.C. § 1117).

A court that made a competitor pay

In Romeo & Juliette Laser Hair Removal v. Assara I LLC, two laser hair removal businesses in New York competed for the same customers. From 2006, negative posts about Romeo & Juliette appeared on Yelp, CitySearch and two other review sites. The court found that people at Assara wrote them under made-up accounts. Some posts described treatments that never happened, and some promoted Assara.

In February 2016 the federal court in Manhattan found Assara and Will Shuman liable under the Lanham Act, and for defamation, disparagement and unfair competition under New York law. It held that the anonymous posts were commercial advertising or promotion (summary of the ruling). The court barred further false or disparaging statements and ordered the defendants to pay $30,000 of the plaintiff’s legal fees. The Second Circuit upheld the judgment in February 2017. The case was filed in 2008, so the route took about nine years from filing to the final appeal.

Not every competitor review can be taken to court

In Gursten v. Doe (Michigan Court of Appeals, March 2021, unpublished), a law firm sued over a one-star Google review with no text that it believed came from a competitor. The court held that a wordless one-star Google review “is an expression of opinion protected by the First Amendment.” It called the competitor theory speculation, because the firm did not know who the reviewer was. It added that the review was opinion “even if it violates Google’s policy.”

For a review that is only a star rating, reporting to Google is usually the practical route. One-star reviews with no text covers what can still be done.

State unfair competition laws

Most states have their own unfair competition or deceptive trade practices law. California’s Business and Professions Code section 17200 defines unfair competition to include “any unlawful, unfair or fraudulent business act or practice” and “untrue or misleading advertising.” Ask a lawyer whether your state’s law lets one business sue another, and what it lets you recover.

Defamation and trade libel

A false statement of fact that harms your business can be defamation, while an opinion such as “worst plumber in town” usually is not. Many states also recognise trade libel, sometimes called injurious falsehood, for false statements about the quality of your goods or services that cost you money. Can you sue for a fake review? explains how courts separate fact from opinion.

Finding out who wrote the reviews

If the reviewer is anonymous, a lawyer can sue an unnamed defendant and ask the court to order the platform to disclose account details. States use different tests for this, and some require evidence that the review is false before they allow it. The deadline to sue for defamation is one year from posting in several states. Can you sue for a fake review? covers the tests and deadlines state by state.

The FTC rule on fake reviews

The FTC Consumer Review Rule (16 CFR Part 465, formally the Trade Regulation Rule on the Use of Consumer Reviews and Testimonials) took effect on 21 October 2024. Section 465.2(a) makes it a violation for a business to write or create a review that misrepresents that the reviewer exists or had experience with “the product, service, or business that is the subject of the review.” The wording is not limited to reviews of the writer’s own business. Section 465.4 bans paying for reviews of a particular sentiment, “whether positive or negative.”

In its notice of the final rule, the FTC said that a competitor who posts fake reviews to make a rival look like a violator “might be liable” under the FTC Act. In December 2025, FTC staff sent warning letters to 10 companies and reminded them that violations can bring a federal lawsuit and civil penalties of up to $53,088 per violation (FTC). You can report a competitor at ReportFraud.ftc.gov. A report to the FTC does not remove a review from Google, so report to Google as well.

What not to do

• Do not post fake reviews of the competitor. It breaks Google’s fake engagement rule and the FTC rule, and it gives the competitor the same Lanham Act claim you have against them. In the Romeo & Juliette case, that conduct ended in a court order and $30,000 of the other side’s legal fees.
• Do not name the competitor in a public reply. An accusation you cannot prove is a defamation risk and can break the FTC rule on public false accusations.
• Do not threaten the reviewer with legal action you have no basis for. The FTC rule bans an “unfounded or groundless legal threat” used to get a review removed. If you want a competitor to stop, have a lawyer send a letter.
• Do not buy positive reviews to outweigh the fake ones. Google can remove them and restrict your profile for fake engagement.
• Do not ask friends to report the same review. More reports of one review add no evidence.

How TrustReviews handles competitor reviews

You connect your Google Business Profile in the TrustOS portal. We read every review at once and show you each one rated 3 stars or less. You choose which reviews we file; every 1-star is selected by default. You see the price and accept the terms in the app before anything is filed. If you have 10 or more bad reviews, the app offers a free 15-minute planning call with your account manager.

We screenshot each review before work starts. Our filing team files each one with Google under its own policy, and Google makes the decision on each review. No one can guarantee that every review comes down, because the platform makes the final decision. A person checks every removal before we count it, and we email you the review and its screenshot when it comes down. You pay for the ones that come down. If a removed review comes back, we file it again at no charge.

Newer reviews are easier to get removed than old ones, so act on a cluster early. Our review monitoring reads each connected profile about once a day and emails you new 1 and 2 star reviews. The Review Auto-filer files every new review of 2 stars or below from the last 14 days, within the monthly limit you set. For Google in general, see Google review removal.
