Is it legal for competitors to bid on your brand name?
Short answer for the US: bidding on your brand as a keyword is generally legal; using your brand in the ad in a way that misleads people is not. Here's where the line is, what courts have said, how Google's rules differ from the law, and what you can actually do.
The short answer
| What the competitor does | Usually legal in the US? | What you can do |
|---|---|---|
| Bids on your brand as a keyword; their ad is clearly about them | Generally yes | Ask them to stop, outbid them with your own brand campaign |
| Uses your brand in the headline or description | Often not, if it suggests a connection or misleads | Google trademark complaint, cease and desist |
| Claims to be "official", or uses your phone number or look | Risky for them: likely confusion or false advertising | Cease and desist, complaint, lawyer |
| Uses a lookalike domain (yourbrand-quotes.com) | Often not, especially if registered in bad faith | Registrar report, domain dispute (UDRP), lawyer |
| Your own affiliate or partner bids on your brand | Depends on your contract | Enforce your terms: warn, reverse commissions, remove |
Bidding on your brand as a keyword
US trademark law asks one main question: is the use likely to confuse consumers about who is selling or who is behind the product? When a competitor only buys your name as a keyword, and the ad people see is clearly theirs, courts have generally found no likely confusion. The keyword is invisible; the searcher sees an ad labeled as an ad, from a different company.
- Network Automation v. Advanced Systems Concepts (9th Cir., 2011): the court said buying a competitor's mark as a keyword is a "use" that trademark law can reach, but that the confusion analysis turns on what consumers actually see, including how the ad is labeled and worded, and how careful the buyers are. It overturned an injunction against the keyword buyer.
- 1-800 Contacts v. Lens.com (10th Cir., 2013): the court rejected the claim that buying a competitor's mark as a keyword was infringement on its own, pointing to evidence that very few searchers clicked the competitor's ads, which made meaningful confusion unlikely.
The practical result: you're unlikely to win a lawsuit just because a competitor shows up on your brand search with an honest ad about themselves. Your tools there are business ones, covered below.
Using your brand in the ad
This is where competitors get into trouble. Ads can cross the line when they:
- put your brand in the headline in a way that suggests they are you or are connected to you ("Acme Insurance – Official Quotes");
- claim to be your official site, use your logo, your phone number or a number that pretends to be yours;
- use a domain or display URL built from your brand, so the ad looks like it's from you;
- make false or misleading claims about you, which can also raise false advertising issues.
Not every mention is unlawful. Truthful comparative ads ("Acme vs. Beta: compare prices") and genuine resellers describing what they sell can be allowed. The question is still whether a reasonable searcher would be misled.
Google's rules vs. the law
Google's Ads trademark policy is separate from the law, and in practice it's the faster tool:
- Google doesn't restrict trademarks as keywords, so it won't stop keyword-only bidding.
- It restricts trademarks in the ad itself (headline, description) for the advertisers you name in a complaint, unless an exception applies (genuine resellers, informational sites, descriptive uses).
- It doesn't restrict trademarks only on the landing page, or in the domain of the display URL.
See the step-by-step Google trademark complaint guide.
Non-bidding agreements between competitors
Some companies settle disputes by agreeing not to bid on each other's brands. That's been controversial. The FTC challenged 1-800 Contacts' agreements with rival retailers as anticompetitive; in 2021 the US Court of Appeals for the Second Circuit set aside the FTC's ruling, holding that the FTC applied the wrong test and hadn't proven harm under the full analysis. Agreements like these aren't automatically unlawful, but they can draw antitrust scrutiny, so get legal advice before signing one.
Affiliates, resellers and partners
With your own partners, trademark law matters less than your contract. You can, and should, prohibit bidding on your brand and its misspellings in your affiliate, reseller, agent and franchise agreements, require them to add your brand as a negative keyword, and say that brand-bid traffic earns no commission. Then enforce it with evidence. See how to stop competitors bidding on your brand and the affiliate letter template.
Outside the US
The European Union reached a similar place by a different route. In Google France v. Louis Vuitton (2010), the EU Court of Justice said Google wasn't infringing by selling trademarks as keywords, and that an advertiser can infringe when its ad doesn't let ordinary internet users easily tell whether the goods come from the trademark owner or someone else. Later cases, such as Interflora v. Marks & Spencer, applied that test to competitors. Rules and practice differ by country, so check locally.
What this means for you
- Find out what they're actually doing: keyword only, your name in the ad, or a lookalike domain. That decides your options. See how to find who is bidding on your brand.
- Keep dated evidence of every ad: screenshots, exact text, domain, search, city, device, and how often.
- Use the fast tools first: a polite request, your affiliate terms, a Google trademark complaint if your name is in the ad, and your own brand campaign.
- Escalate with a lawyer when ads keep misleading customers. Your evidence is what makes that worthwhile.
StopBrandBidding.com monitors your brand from the US cities and devices you choose, several times a day, keeps dated screenshots of every ad that uses your name, and prepares the complaint answers and letters for each advertiser.
Questions
Is it legal to bid on a competitor's brand name in Google Ads?
In the US, buying a competitor's trademark as a keyword is generally not infringement on its own; courts look at whether the ad itself is likely to confuse people. Using the trademark in the ad in a way that suggests a connection, or a misleading ad, can be.
Can I sue a competitor for bidding on my brand?
You can, but US courts have generally not found keyword bidding alone to be infringement when the ads are clearly labeled and not misleading. Claims are stronger when the ad text uses your mark confusingly, implies affiliation or uses a lookalike domain.
Can competitors use my brand name in their ad text?
Google restricts named advertisers from using your registered trademark in ad text once you file a complaint, with exceptions for genuine resellers, informational sites and descriptive uses. Ad text that misleads people about who is advertising can also be infringement or false advertising.
Can I stop my affiliates from bidding on my brand?
Yes. Affiliates, resellers and partners are bound by your agreements, so you can prohibit brand bidding, reverse commissions on that traffic and remove partners who break the rules.
Is bidding on my own brand name worth it?
For most brands that face competitor bidding, yes: your brand clicks are usually cheap, you take the top spot, and competitors pay more for lower positions. Test it with the campaign on and off.
