Can competitors use your trademark in Google Ads?

Google’s trademark policy splits a search ad into two zones that get treated completely differently. Bidding on a trademark as a keyword — including a competitor’s brand name — is not restricted, and neither is using it in the second-level domain of the ad’s display URL. Putting that same trademark inside the ad itself, as a direct competitor, is restricted and gets investigated on complaint. Same word, same auction, opposite outcome, depending entirely on which zone it sits in.

That split isn’t arbitrary, and it isn’t really about trademarks at all — it’s about what the person searching can see. A keyword is a targeting instruction: it decides which ads are eligible to show for a given query, but it never renders on the page, and nobody reads a list of an advertiser’s keywords before they click. Ad text is the opposite — the one part of the auction the searcher actually reads before deciding who to trust with their click. Google’s policy protects the second thing, not the first, because that’s where someone can actually be misled about who they’re dealing with. Once you see it that way, the rule stops looking like a loophole and starts looking consistent: anything invisible to the searcher sits outside the policy’s reach, and anything they read sits inside it.

It’s worth being precise here, because “in the ad” is doing a lot of work. Under the trademark policy it means the visible copy a competitor controls and a searcher reads before clicking: the headline and the description lines. It does not mean the keyword list behind the ad, and it does not mean the landing page the ad points to — Google’s policy is explicit that the trademark has to be used in the ad, not only on the ad’s landing page. The business name shown alongside the ad is governed separately, by Google’s business-information and brand-verification rules rather than the trademark policy, but it’s another place a searcher reads a competitor’s identity, so it’s worth watching for the same reason.

• Headline and description text — the words the searcher reads directly on the results page. This is the core of what “in the ad” means under the trademark policy.
• Business name — the advertiser identity shown with the ad. A searcher reads it, but Google handles it under its business-information and brand-verification rules, not the trademark policy — a separate route to the same concern.
• Second-level domain of the display URL — explicitly carved out by Google’s trademark policy as something that will not be restricted, even though it’s technically visible in the ad.
• The keyword itself — never visible to the searcher at all, which is precisely why it sits outside the policy regardless of whose trademark it is.
• The landing page — visible only after the click, so trademark use there is a different question from what’s in the ad.

The detail people most often get backwards: that carve-out is narrower than “the display URL” in general — it’s specifically the second-level domain, not the full URL structure. The line runs through the headline and description, and confusing or misleading use anywhere in that visible copy is what gets investigated.

Separate from what Google’s own policy restricts, there’s a body of trademark law — nominative fair use — that explains why referring to a competitor by name isn’t automatically a violation in the first place. This is general information about a US legal doctrine, not legal advice, but it’s the backbone of a lot of legitimate comparative advertising, and it’s worth understanding on its own terms.

The idea is simple: sometimes the only way to talk about a specific product is to use its name. If you’re comparing your service to a named competitor, there’s often no substitute word that identifies them as clearly as their own trademark does — so using the mark to refer to them isn’t inherently infringing. Courts applying this doctrine generally look at three things.

1. The product or company isn’t readily identifiable without using the mark — there’s no other name that would tell the reader who you mean.
2. Only as much of the mark is used as is reasonably necessary to identify them — the name itself, not their logo, colours, or broader brand identity, if a plain reference would do.
3. Nothing in the use falsely suggests sponsorship or endorsement — a reasonable reader shouldn’t come away thinking the trademark owner approved of or is affiliated with what’s being said.

Notice what this doctrine does and doesn’t settle. It’s a general legal principle about referring to a competitor’s actual product, not Google’s ad policy, and not a guarantee any specific ad clears both bars — an ad can satisfy nominative fair use in principle and still fall foul of Google’s policy if the wording implies endorsement, or vice versa. Treat the two as related but separate tests, and this section as a starting point for a conversation with counsel, not a substitute for one.

A few categories of legitimate use sit in the middle of this line and cause most of the confusion. Google’s policy allows a trademark to appear in ad text for resellers, informational sites, and other uses that meet its specific conditions — genuine sellers of the product, and sites that describe it accurately. That’s a real exception: “the trademark is in the ad” doesn’t automatically mean “this is a violation,” even once you’re past the keyword-versus-ad-text distinction.

This piece stays narrow by design, so it won’t re-walk those conditions in full — that depth belongs in our guide to Google’s trademark policy. The point worth taking here: it depends on who’s using the mark and what they’re saying, which is why Google reviews these case by case rather than applying a blanket rule.

Here’s the angle that catches advertisers off guard, because it has nothing to do with a competitor targeting them — it’s a way you can accidentally trip this policy against yourself. Dynamic Keyword Insertion lets an ad automatically insert the searcher’s matched keyword into the ad’s headline or description at serve time, so the ad text feels tailored to whatever the person searched. That’s the entire mechanism, and it’s also the entire problem.

If a competitor’s trademarked term is anywhere in the keyword list a DKI ad pulls from, a search for that term can cause your own ad to render their trademark inside your visible ad text — automatically, without anyone typing it in. You didn’t decide to reference them; the insertion logic did, at the moment the ad served. But “a machine did it” doesn’t move the outcome out of the ad-text zone described above: the ad a searcher reads is the ad a searcher reads, regardless of who — or what — wrote that particular word.

The fix sits entirely on the targeting side, not the ad-copy side, which is what makes it easy to miss until it’s already happened. Two habits close the gap.

• Don’t run DKI on ad groups whose keyword lists are broad or brand-heavy — anywhere a competitor’s exact trademarked term could plausibly be a matched keyword, insertion is the wrong tool for that ad group.
• Add known competitor trademarks as negative keywords on any campaign using DKI, so those terms can’t match into the ad group DKI is pulling from in the first place.

Audit this the same way you’d audit any keyword list — periodically, and whenever you add DKI to a new ad group — rather than assuming it was fine once and stays fine. Keyword lists drift as campaigns get expanded, and a term that was safe when the ad group launched can stop being safe the day someone adds a broader match type.
