In today’s digital age, many customers rely on online reviews when deciding where to eat, shop, and even do business. Reading reviews is just as effortless as posting them. With just a few clicks, anyone can post feedback that reaches thousands, and sometimes millions of people. While honest criticism is part of doing business, not every negative review is fair or lawful. Some posts can contain false claims that can seriously damage a business’s reputation. As a business owner, knowing when online speech is protected and when it crosses the legal line into defamation is essential.
Defamation occurs when someone makes a false statement of fact that harms the reputation of a person or business. In the context of online defamation, it often appears as a review, a social media post, or a comment that is untrue, but is presented as factual. The First Amendment protects free speech, but it does not protect knowingly making false statements that damage someone’s reputation or livelihood.
As a business owner, there are several elements you must prove to establish defamation. First, the reviewer made a false statement of fact about the business. Second, that statement was communicated to at least one third party, such as through a public review or a post. Third, the reviewer acted negligently or intentionally in making the statement. Finally, the statement caused harm to the business, such as through lost revenue or customer impact.
Now, distinguishing between an opinion and a fact is critical. If a false statement can be verified, that is, it can be proven untrue, this may support a defamation claim. For instance, if a customer writes that “This company overcharged me after advertising a lower price,” it can be fact-checked. On the other hand, if a customer posts a review, “I hated the service,” this is an opinion and may not meet the defamatory threshold.
As noted, not all harsh reviews are defamatory. Even negative opinions are generally protected speech when they reflect personal experience and judgment. However, when someone presents false claims as facts or disguises them as “opinions,” it may be defamatory. For example, stating, “In my opinion, this business commits fraud,” suggests a factual allegation. If the claim is untrue, it may be defamatory.
Essentially, the key question to ask is whether the statement can be proven true or false. If it can, and it’s untrue and harmful, it may cross the line into defamation.
If your business is targeted by defamatory content, an attorney can step in promptly before the situation escalates. The process may start with a cease-and-desist letter, demanding the removal of the false statements. If that doesn’t work, your attorney can evaluate whether filing a defamation lawsuit makes sense based on evidence, damages, and the source of the post.

Not every negative review is defamatory, and understanding the distinction matters before you consider legal action. Defamation — whether libel (written) or slander (spoken) — requires: (1) a false statement of fact, not opinion; (2) published to a third party; (3) with the requisite level of fault (negligence for private figures, actual malice for public figures); and (4) damages. Pure opinion — “I hated this restaurant” or “the service was terrible” — is constitutionally protected under the First Amendment and cannot form the basis of a defamation claim. The statement must be one that could be proven true or false.
The leading Supreme Court case on opinion versus fact in defamation is Milkovich v. Lorain Journal Co., 497 U.S. 1 (1990), which rejected a categorical First Amendment protection for all “opinion” and instead required courts to evaluate whether the statement could be reasonably understood as stating an actual fact. Applied to online reviews, statements like “this contractor stole $5,000 from me” or “this doctor falsified records” are statements of fact that can be true or false. “This plumber is the worst I’ve ever hired” is classic opinion. The line matters because filing a defamation suit over protected opinion can expose you to anti-SLAPP motions and fee-shifting.
Section 230 of the Communications Decency Act (47 U.S.C. § 230) immunizes online platforms — Google, Yelp, Tripadvisor, Angi — from liability for content posted by third-party users. The platform is not the publisher of the defamatory review; the individual reviewer is. This means your defamation lawsuit must target the person who wrote the review, not the platform hosting it. Courts have almost uniformly enforced this immunity broadly, dismissing claims against platforms for hosting false reviews, even malicious or commercial fake reviews.
Section 230 does not protect the reviewer. The individual who posted a false and defamatory review about your business is fully subject to a defamation claim. The challenge is identifying who they are, especially if they posted anonymously or under a pseudonym. To unmask an anonymous reviewer, you can file a John Doe lawsuit, then use the discovery process to subpoena the platform for the reviewer’s account information (IP addresses, email addresses, account details). Courts apply varying standards for such subpoenas — some require a preliminary showing of a viable defamation claim before ordering disclosure, protecting legitimate anonymous speech while exposing bad actors.
When fake negative reviews are posted by a competitor — not a disgruntled customer — you have additional legal options beyond standard defamation. The Lanham Act § 43(a) (15 U.S.C. § 1125(a)) provides a federal cause of action for false advertising and false statements in commercial contexts. A competitor who posts fake one-star reviews under fictional customer accounts is making false representations about your business in commercial speech, actionable under the Lanham Act. Damages can include the competitor’s profits from the diversion of trade caused by the false reviews and, in exceptional cases, attorney fees.
The FTC also regulates fake reviews. Its August 2024 final rule on fake reviews and testimonials (16 C.F.R. Part 465) explicitly prohibits businesses from creating fake reviews, paying for fake reviews without disclosure, and suppressing negative reviews. Violations are subject to civil penalties up to $51,744 per violation. The rule makes it an unfair or deceptive practice for a competitor to post or procure negative fake reviews targeting another business. If you suspect a competitor is behind a coordinated fake-review campaign, the FTC complaint process is an available avenue alongside civil litigation.
Before filing a defamation claim over an online review, understand the anti-SLAPP (Strategic Lawsuit Against Public Participation) landscape in your jurisdiction. California’s anti-SLAPP statute (Code Civ. Proc. § 425.16) and many similar laws in other states allow defendants to bring a special motion to strike claims that arise from constitutionally protected activity — including reviews about a business’s products or services. If you file a defamation claim and the defendant successfully brings an anti-SLAPP motion, your case is dismissed and you may be required to pay the defendant’s attorney fees.
This means frivolous or marginal defamation claims over negative reviews carry real financial risk for plaintiffs. Before filing, have an attorney evaluate whether the review contains an objectively false statement of fact (not mere opinion), whether you can demonstrate actual damages or defamation per se (statements false on their face that are harmful to a business’s reputation), and whether the anti-SLAPP law in your state applies. California, Texas, Nevada, and the District of Columbia have robust anti-SLAPP statutes. New York’s statute was significantly strengthened in 2020 (CPLR § 3211(g)) and now covers matters of public concern broadly.
When you discover a false and harmful online review, the immediate priority is documentation: screenshot the review with the URL, date, reviewer profile, and any other visible information. Do not wait — platforms sometimes remove reviews for unrelated reasons, and having a preserved record is essential for any legal action. Then report the review to the platform. Google, Yelp, and most major review sites have policies against fake and defamatory reviews; a policy-based removal is faster and cheaper than litigation.
If the review persists and the damage is significant, engage an attorney to evaluate the defamation claim, assess anti-SLAPP risk, and determine whether a cease-and-desist letter to the reviewer is appropriate. A carefully worded letter that does not cross into harassment territory can prompt a retraction or removal. If the reviewer is a competitor, a formal investigation into the source of a coordinated fake-review campaign — using discovery tools including subpoenas for platform records and IP logs — may reveal the responsible party.
