What to do when a competitor leaves a fake review

Here’s the sequence, in order: document the review before touching anything, post one public response that never mentions a competitor, flag it with Google citing the specific policy it violates, and escalate to a demand letter only if you can actually identify who’s behind it. That’s the whole answer. The rest of this post is how to do each step without sabotaging the next one - because the most common mistake, writing “THIS IS A FAKE REVIEW FROM OUR COMPETITOR” in the response box, manages to sabotage all four at once.

One framing note before the steps: you almost never get proof it’s a competitor. What you get is a pattern strong enough to act on. The playbook below works whether the author turns out to be a rival owner, their cousin, or a stranger with a grudge.

Step 1: document before you flag

Flagging can get a review removed - and removal destroys your evidence. If this ever escalates to a demand letter or a platform appeal, you’ll need the record. Take a full-page screenshot showing the review text, the star rating, the reviewer name, and the date together. Save the reviewer’s profile URL, and screenshot the profile itself.

The profile is usually where the pattern lives. The classic tells: an account created recently with one review (yours), or an account whose entire history is 1-stars for businesses in your category - a roofer who’s reviewed four other roofers and nothing else is not a customer, he’s a colleague. Also check the review text against reality: services you don’t offer, a visit on a day you were closed, a staff name nobody’s ever had. Then check your own records - CRM, booking system, invoices - and note, in writing, that no matching customer exists. That written negative is your strongest single piece of evidence.

Step 2: respond publicly - and don’t accuse anyone

The response isn’t for the fake reviewer. It’s for the next fifty prospects who’ll read the review before Google gets around to your flag. They need exactly two signals: you checked, and there’s no record of this person.

Here’s what that looks like in practice. Summit Air & Heating, an HVAC company in Chattanooga, got this review on a Tuesday:

“Tech cracked our heat exchanger during a routine service and the company refused any refund. Stay away from these crooks.”

No matching name in eight years of service records, and the reviewer’s other reviews were 1-stars for two other Chattanooga HVAC companies in the same month. The owner replied:

“We take damage claims seriously, so we searched eight years of service records for your name and found no appointment, invoice, or service call. If we’ve missed something, call me directly at the number on our site and I’ll pull the file while you’re on the phone. We’ve reported this review in the meantime. - Glenn, owner.”

Specific, checkable, zero theatrics - and notice the absence of the word “fake” doing accusatory work, and the absence of any competitor’s name. Naming a competitor you can’t prove wrote it is how the target of a fake review becomes the defendant in a defamation claim. If you want a starting structure for this exact wording problem, there’s a fake-review response template built around the no-record framing.

The review came down eleven days later. The response had already been live for ten of them - which is the point. Removal is slow and uncertain; the response is instant and yours.

Step 3: flag it like you only get one shot

Because you nearly do. Flag the review through Google Business Profile, choosing the specific violation - Google’s prohibited content policy (updated 2025) bans both “fake engagement” and conflict-of-interest reviews from competitors. If Google’s first pass finds no violation, you get a single appeal, and that’s the end of the internal road. So don’t flag on day one with “this is fake, trust me.” Flag with the pattern: no customer record, the reviewer’s profile history, the factual impossibilities in the review text. A reviewer at Google spends seconds on your flag. Hand them a verdict they can reach in those seconds.

Step 4: escalate only with a name

If the pattern points somewhere specific - the reviewer profile matches a rival’s employee, or the review repeats phrasing from a dispute only one competitor knows about - a lawyer’s demand letter changes behavior fast, because a competitor (unlike a troll) has a business to lose. Fake reviews from a rival can support defamation and unfair-competition claims, and platforms themselves have gone after the supply side: Google sued a fake-review broker in federal court in October 2024. But know the real costs before you commit - our breakdown of suing over a false review covers the five-figure price tag and the anti-SLAPP traps. Most cases should end at step 3.

The part nobody tells you

A single fake review hurts you less than your reaction can. One 1-star sitting under a calm, specific, no-record response is close to harmless - readers are better at spotting fakes than platforms are, and your reply is what tips them off. An unhinged ALL-CAPS accusation under the same review does more damage than the review did, and it’s permanent in screenshots even if the original gets removed. The fake review is your competitor’s content. The response is yours; it’s the only part of this exchange you fully control, and the principles in our negative review response playbook apply doubly when the review is fabricated.

And if it’s not one review but ten in a weekend - that’s a different animal with a different clock. Use the 72-hour crisis playbook instead.
