Can you mention competitors in ads? What's legal and what gets you sued

Comparative ads are everywhere once you start noticing them: the side-by-side feature chart, the "switch from Brand X" headline, the "twice the battery, half the price" claim. And yet the moment you type a rival's actual name into your ad copy, the nerves kick in. Will they send a cease-and-desist? Will the platform suspend your account? The short answer is that you're allowed to do this, within limits. Naming a competitor is a legitimate, long-established tactic, not a legal trap. What follows is the whole picture in one place: the US verdict, the trademark rules, what Google and Meta actually allow, how the UK and EU differ, and concrete examples of safe versus risky phrasing.

Can you mention competitors in ads?

Yes, in the US you can name and mention competitors in ads. The practice has a name, comparative advertising, and it's legal. The Federal Trade Commission doesn't just tolerate it; its official policy "encourages the naming of, or reference to competitors" and states that industry self-regulation "should not restrain the use by advertisers of truthful comparative advertising." You can read the policy yourself in 16 C.F.R. § 14.15.

The logic is simple. When you tell shoppers exactly how your product stacks up against a named alternative, you give them real information to decide with, and the FTC treats that as a good thing for the market. So the freedom to name names isn't a loophole you're sneaking through; it's the intended state of the law.

The whole game hinges on one word: truthful. Everything else on this page is really just an unpacking of what "truthful" demands, and where each advertising platform draws its own line on top of it.

What rules do you have to follow when you name a competitor?

The freedom to name a rival comes with three non-negotiable rules: be truthful, be able to prove it, and don't confuse anyone. Get those three right and you're on solid ground. Get one wrong and you've handed the competitor a reason to come after you.

Here's what each one means in practice:

• Truthful and not deceptive. The FTC allows even unflattering, disparaging comparisons "so long as it is truthful and not deceptive." You can say your product is better. You can not say something false or create a misleading overall impression.
• Substantiated before you run it. You need evidence for a comparative claim before it goes live, not scrambled together after someone challenges you. And comparative claims can't be held to a higher proof standard than any other claim you'd make, so the bar is the normal one: can you back this up?
• No false affiliation or confusion. You can't imply the competitor endorses you, sponsors you, or is somehow connected to you. Naming them to compare is fine; naming them in a way that suggests a partnership that doesn't exist is not.

The stakes are real, which is the part that keeps marketers up at night. A false or misleading comparison is actionable under the Lanham Act, 15 U.S.C. § 1125(a): a competitor you named can sue you for false advertising if your claim is untrue or deceptive, and the FTC can step in too. So "can I get sued?" has an honest answer. You can, but generally only when the claim was false, misleading, or unprovable. Keep it true and documented, and you've removed the ammunition.

Can you use a competitor's name or trademark in your ad?

Using a competitor's trademark feels like the riskiest part, but yes, you can use their name in your ad, thanks to a doctrine called nominative fair use. Trademark law exists to stop you from using someone's mark in a way that confuses customers about who's actually selling a product. It does not stop you from using a rival's name to refer to their real product for the sake of comparison.

The guardrails are common-sense. Use only as much of the mark as you need to identify it, and don't imply the trademark owner sponsors or endorses you. Say "faster than Brand X" and you're referencing their product truthfully. Recreate their exact logo and color scheme so your ad looks like it came from them, and you've crossed into confusion.

The test is confusion, nothing more.

This is also why compatibility claims are fine. A company selling phone cases can say "compatible with the iPhone," and a challenger brand can say "an alternative to Brand X," because both are truthful references, not claims of endorsement. You're describing a real relationship between the products, which is exactly what the doctrine protects.

One caveat worth flagging early: the law lets you use a competitor's name, but individual ad platforms layer their own rules on top, and Google's run stricter than the law itself for your visible ad text. More on that below. (If you're weighing whether to go further and use a rival's actual logo, that's a separate question with its own risks, covered in our guide on using a competitor's logo in your ad.)

What can you safely say, and what gets you in trouble?

The line almost always comes down to one test: is the claim a provable fact, or an unprovable put-down? Facts you can document are defensible. Insults and vague swipes are not.

Safer (truthful, provable)	Riskier (unprovable or misleading)
"Half the price of Brand X for the same features" (when the prices are current and accurate)	"Brand X is a rip-off" (pure disparagement, not a fact)
"Rated higher than Brand X in the 2025 [named study]" (with the source cited)	"Everyone knows Brand X is slower" (no evidence behind it)
"Works with Brand X's file formats" (a true compatibility statement)	"Brand X sells your data" (defamatory if you can't prove it)
"Unlike Brand X, we include onboarding at no extra cost" (verifiable)	Copying Brand X's logo or look so your ad seems endorsed

The pattern is easy to remember. If you couldn't defend the line in front of a judge with a document in your hand, is it really worth running? Rewrite it until the answer is easy.

Can you use a competitor's name in Google Ads?

In Google Ads, you can bid on a competitor's name as a keyword, but you generally can't put their name in your visible ad text. These are two different things, and conflating them is where most people get tripped up.

The first is keyword bidding. Targeting a rival's brand name as a keyword so your ad shows when people search for them is allowed and extremely common. Google won't restrict trademarked terms used as keywords, even if the trademark owner complains, and US courts have largely sided with advertisers who bid on competitor terms. (We go deeper on this in our guide to using competitor brand keywords in Google Ads.)

The second is ad copy, and here Google is stricter. Its trademark policy limits using a trademark in your actual ad text to the brand owner, their authorized resellers, or genuinely informational sites, and explicitly not "ads referring to the trademark for competitive purposes." In plain terms: put a competitor's name in your headline and your ad will usually get disapproved once they file a trademark complaint.

Watch out for one automated trap. Dynamic Keyword Insertion can pull a searched competitor term straight into your headline without you writing it there, tripping the same rule. If you bid on branded terms, exclude them from any DKI ad group so a rival's name doesn't sneak into your copy.

Can you mention competitors in Facebook and Meta ads?

Meta has no clause literally titled "comparative advertising," so the rules live elsewhere, but yes, you can mention competitors in Facebook and Meta ads. There's no blanket ban on naming a rival.

Two of Meta's Advertising Standards do the governing work. Ads must not infringe a third party's intellectual property, including trademark and copyright, and must not "be likely to confuse people about the source, sponsorship or affiliation" of a product or service. A truthful comparison that names a competitor clears both. Using their logo so your ad looks endorsed, or making a claim you can't back, does not.

Worth knowing: Meta enforcement is largely complaint- and review-driven, so a competitor can report your ad and trigger a manual look. That's one more reason to keep every claim provable before you publish. (And don't confuse Meta's separate "Brand Usage in Ads" page with this; that one governs use of Meta's own brand assets, not your competitor's.)

Do the rules differ in the UK and EU?

Yes, the UK and EU are noticeably stricter than the US. Where American law mostly asks that a comparison be truthful and non-deceptive, the EU's Comparative Advertising Directive (2006/114/EC) makes naming a competitor lawful only when it satisfies every condition on a checklist.

To be permitted, a comparative ad must:

1. not be misleading;
2. compare goods or services meeting the same needs or intended for the same purpose;
3. objectively compare material, relevant, verifiable, and representative features;
4. not create confusion between you and the competitor;
5. not discredit or denigrate the competitor's trademarks or products;
6. not take unfair advantage of the competitor's reputation; and
7. not present your goods or services as imitations of theirs.

All of these have to be met, not just most of them. So if you run ads in the UK or EU, treat naming a competitor as a checklist exercise rather than a judgment call, and make sure the comparison is objective and verifiable feature by feature.

How can you see how competitors actually phrase their comparative claims?

The fastest way to stay on the safe side is to read how your competitors already word their comparative claims before you write your own. This is really just competitor ad research with a legal purpose: the public ad libraries hold every live comparison, but browsing the Meta Ad Library, the Google Ads Transparency Center, and LinkedIn one at a time is slow. Proxy is a free tool that lets you pull a competitor's live ads and read the copy inside the AI assistant you already use, so you can see which comparison angles rivals actually run, and how carefully they hedge a claim, then pattern-match to phrasing you know is defensible.

So where does this leave your next ad?

It leaves you freer than it feels from the outside, because naming a competitor isn't the legal minefield the nerves make it out to be. Comparative advertising is a legitimate, FTC-blessed tactic; the discipline is simply keeping every claim provable and respecting each platform's rules on how a rival's name can appear. Draft the line you want to run, then ask yourself one question: could I prove this with a document? If the answer is yes, you're usually clear. If the ad will run in the UK or EU, run it past the directive's checklist first, and if it's going in Google copy rather than a keyword bid, check the trademark rule before you hit publish. Reading how rivals already word their own comparisons is a fast way to calibrate what's normal in your space. Name the competitor. Just make sure you can back it up.
