Can you use competitor brand keywords in Google Ads? Yes, with one big caveat

Bidding on a competitor's name is one of the most-asked "wait, is this even allowed?" questions in paid search. The honest answer comes in two halves that people constantly mash together. So let's pull them apart and quote the policy that actually governs this. Then we'll get to the part nobody explains well: where the line sits, what it costs, and how to see who's already crossing it against you.

Can you bid on a competitor's brand keyword at all?

Yes, you can add a competitor's brand name to your keyword list in Google Ads, and doing that alone breaks neither Google's policies nor trademark law. Advertisers have been bidding on each other's brand terms for two decades; the practice even has a name, conquesting, and it's a standard play in competitive categories. Type a rival's brand into your keyword planner, add it as a keyword, and your ad becomes eligible to show when someone searches for them.

The catch isn't the keyword. It's what your ad then says. Google treats the keyword that triggers your ad and the text that appears in your ad as two completely separate questions, with two completely different rule sets. Get that distinction right and most of the confusion around competitor brand keywords in Google Ads disappears.

Can you put a competitor's trademark in your ad copy?

You generally can't: putting a competitor's trademarked name in your ad headline or description is where Google draws its line. The keyword can be their brand; the visible copy cannot casually borrow their trademark to imply you're them, beat them, or partner with them. This is the half that actually gets accounts in trouble, and it's the half most "just go for it" advice skips.

Here's the split in practice:

• Allowed: bidding on the competitor's brand name as a keyword; using it in the second-level domain of your display URL where the policy permits; writing your own differentiated copy that never names them.
• Not allowed: their trademark in your headline or description ("Switch from [Brand]", "Better than [Brand]", "[Brand] deals"); anything that implies affiliation or confuses which company the ad is from.

That "Better than [Brand]" phrasing feels harmless, it's arguably true, even. But a competitor's trademark used that way in live ad text is exactly what a complaint targets. Google's stated concern is copy that misleads, and a rival's name in your headline is the fastest route there. You can read the full Google Ads Trademarks policy for the exact wording; it's shorter than you'd expect.

What does Google's trademark policy actually say?

Google's Trademarks policy says, in plain terms, that it doesn't restrict trademarks used as keywords, only trademarks used in ad text, and even then only when the trademark owner complains. Two sentences, and they resolve most of the argument.

The policy is explicit that using trademarks as keywords, and using them in the second-level domain of an ad's display URL, are not restricted. What may be restricted is a trademark inside the ad copy when it's used in a way that's confusing, deceptive, or misleading. And enforcement isn't proactive: Google acts "when a trademark owner submits a complaint to Google about the use of their trademark."

No complaint, no review. This is why you'll see competitors openly running each other's names for months, nobody filed.

When a complaint does land and sticks, the first consequence is usually ad disapproval, not an account ban. Your ad stops running; you fix the copy; you move on. Suspension is reserved for repeat or clearly deceptive behavior, impersonating the brand, or ignoring disapprovals and relaunching the same violating copy after it's pulled. So the realistic risk of naming a rival in your text is a dead ad and a wasted afternoon, not instant account death. Still worth avoiding.

What are the exceptions that let you name a brand in your ad?

There are a few genuine exceptions where Google permits a trademark inside your ad text. They're narrower than most marketers assume. Fit one cleanly and you can name the brand in your copy; stretch to fit one and expect the disapproval. Here's the full set, not just the "resellers" line most guides stop at:

Exception	What it lets you do	The catch
Reseller / resale-facilitating	Name the brand if your landing page is primarily dedicated to selling, or clearly facilitating the sale of, that brand's products or services	The page has to genuinely sell it, with commercial detail; a thin affiliate bridge page won't hold
Compatible parts / components	Name the brand to sell components, replacement parts, or compatible products	Folded into the reseller clause; the product has to actually be compatible, and the page has to show it
Informational	Name the brand if the page's primary purpose is to give informative detail about the trademarked product, or is an index of results	"Informational" means genuinely informational, not a lightly-disguised sales page
Descriptive / ordinary meaning	Use the term where it's descriptive in its ordinary sense	Only works when the word has a real generic meaning apart from the brand

One important update sits on top of all of this. As of February 2025, Google's enforcement went advertiser-specific. A complaint now restricts only the advertisers Google believes were named in it, rather than knocking the term out across the board. So an unrelated advertiser doesn't get swept up in someone else's dispute. At the same time, the old Third-Party Authorization request form was retired. That was the workflow brands used to pre-approve specific resellers, and eligibility now flows directly from the exceptions above. Google didn't put out a splashy press release, but multiple 2025 practitioner guides report both shifts consistently. If you used to operate under a written authorization, re-check whether the underlying exception still covers you on its own.

Is bidding on a competitor's brand actually legal, or can they sue you?

In the US, bidding on a competitor's trademark as a keyword is generally legal, courts have repeatedly declined to treat keyword selection alone as trademark infringement. "Legal" and "against Google's policy" are genuinely different questions, and blurring them is where a lot of fear-mongering comes from. One is trademark law; the other is a private company's ad rules.

The case law is the reassuring part. In Rosetta Stone v. Google, the Fourth Circuit revived Rosetta Stone's claims in 2012, but the parties settled, and most commentators read the saga as leaving keyword bidding lawful in practice. 1-800 Contacts v. FTC went further. There, the Second Circuit in 2021 struck down agreements that banned rivals from bidding on each other's trademarked keywords, treating those restraints as anticompetitive, a strong signal that the bidding itself is normal competition, not a tort. (You can read the Second Circuit's 1-800 Contacts opinion if you enjoy that sort of thing.)

Outside the US, the ground shifts. In the UK and EU, keyword use can cross into infringement when the ad muddies the line. The test is whether a reasonably attentive person can tell the advertiser isn't connected to the brand, the "origin function." In Interflora v. Marks & Spencer, the UK High Court found M&S's bidding on "interflora" infringing. A chunk of searchers, the court held, couldn't tell M&S wasn't part of the Interflora network. None of this is legal advice for your situation, if you're in a litigious category or a stricter jurisdiction, run it past a lawyer. But the sky-is-falling framing rarely matches the record.

How much does bidding on competitor keywords actually cost?

Expect to pay more and convert less, that's the honest answer to how adding competitor keywords affects your Google Ads, and it's true almost everywhere. You're buying clicks from people who typed a different company's name, on terms where Google's own quality signals work against you. Three things drive the premium.

First, the raw CPC. Competitor conquesting terms typically run about two to four times the cost of defending your own brand terms. Brand-defense clicks often sit around $2-$3; competitor terms commonly land in the $5-$15+ range, and climb well past $50 in legal, insurance, and enterprise SaaS. For context, the cross-industry average Search CPC was roughly $2.96 in early 2026, so competitor terms are firmly above baseline.

Second, Quality Score mechanics quietly tax you. You can't put the competitor's name in your ad or point the landing page at their brand, so ad relevance and landing-page match stay low. And low Quality Score means higher prices. WordStream's benchmark data has long pegged accounts with Quality Scores of 8+ at CPCs around 37% below the median. Accounts scoring 4 or below pay roughly 64% more for the same clicks. Competitor keywords structurally live in that expensive bottom band.

Third, the conversion penalty. Someone searching a rival's name usually wants that rival; some aren't even in-market (existing customers hunting a login, or job seekers who'll never buy). The intent mismatch is real. App-store data offers a useful illustration. Own-brand queries there can convert near 85%, while the top result on a generic term converts closer to 25%. That's a different platform, not a Google Ads figure. But the direction holds: competitor terms convert below your own brand terms, sometimes far below. The math only works when your differentiation is sharp enough to flip a skeptic.

What are the traps that get you in trouble by accident?

Two Google Ads features can drop a competitor's trademark into your ad automatically, and both create a complaint-eligible violation you never intended to make. These catch careful advertisers who'd never type a rival's name into a headline.

• Dynamic Keyword Insertion (DKI): DKI drops the triggering search term into your headline, so a competitor's brand keyword can surface their trademark in your ad text. Fix: keep competitor keywords out of any ad group that uses DKI.
• Performance Max and automatically-created assets: these can generate copy that names the brand on their own. Fix: turn automatically-created assets off on conquesting campaigns, and review PMax asset suggestions before they go live.

Neither is exotic. Both are default-friendly settings doing exactly what they're designed to do, which is the whole problem.

Is bidding on a competitor's brand actually worth it?

It can be worth it, but only when your differentiation is sharp and your landing page is built to convert skeptical traffic, otherwise you're paying a premium for clicks that bounce straight back. This is a judgment call, not a compliance question, and it's where I'd spend the most thinking before adding a single competitor keyword.

It tends to work when you have a real reason for someone to switch and a page built to make that case, a genuine feature gap, or a migration offer worth changing vendors for. Softer angles like "[Competitor] alternative" often outperform bidding on the raw brand term. They catch people already shopping around, rather than people loyal to the name. It tends to fail when your differentiation is thin, your budget is small, or your rival is the retaliating type. Provoke a bidding war and they'll start bidding your brand back, dragging up the CPC on your own cheapest, highest-converting traffic. A bad trade you started. Brand defense, run well, can post strong numbers, one widely-cited case claims an 8x return and six figures in annual savings. Which is exactly why an angry competitor has every reason to come after yours. Decide whether you can afford the fight before you pick it.

How can you see who's bidding on your brand and what their ads say?

You've got three practical ways to see who's bidding on your brand name and read their actual ad copy: Auction Insights, the Ads Transparency Center, and simply asking your AI assistant. Each answers a slightly different question, and using them together is how you catch a rival naming your trademark in their text before it costs you.

1. Auction Insights tells you who you're up against. Inside Google Ads, it shows which advertisers appear in the same auctions as you, with impression share and overlap rate, but never their keywords, bids, or actual ad copy. It's the "am I being targeted?" signal, not the "what does their ad say?" one. Google's Auction Insights documentation covers the metrics.
2. The Google Ads Transparency Center shows a verified advertiser's live ads and formats. The limitation: you have to start from an advertiser's name or domain, and you can't search it by the words inside the creative, so cross-referencing who's running what against your brand gets tedious fast.
3. Ask your AI assistant. Proxy is a free MCP server that connects the Google, Meta, and LinkedIn ad libraries to ChatGPT, Claude, or Cursor. Instead of tab-hopping between Auction Insights and the Transparency Center, you ask in plain language which competitors are running search ads. You read their live copy in one place. That's genuinely useful for spotting whether a rival is naming trademarks in their ad text or running a comparison angle at you. There's a trade-off worth stating, though. Proxy runs inside an AI client, and the ad libraries themselves are public and free if you'd rather click through them by hand. Proxy's free tier is 30 credits a month (10 a day) with no credit card, and it doesn't cover TikTok yet.

Is the rule different on Bing, Amazon, or outside the US?

Broadly, the keyword-yes / ad-text-restricted shape holds, with local flavor. Microsoft Ads (Bing) follows much the same approach as Google. Amazon Ads lets you target a competitor's brand as a keyword but is stricter about naming them in the creative. And the EU and UK lean harder toward the trademark owner, as Interflora showed. When in doubt, check the specific platform's policy.

Where's the line between smart competition and stealing a rival's customers?

Here's the part the compliance answer doesn't settle: intercepting someone who's actively searching for a named competitor is either sharp competition or quietly riding on a brand you didn't build, depending entirely on where you're standing. From your seat it's a legitimate offer put in front of an in-market shopper; from theirs it's showing up at a door with someone else's name on it. And the same transparency tools that let you scout a rival's ads let them scout yours. The visibility runs both directions, which keeps everyone a little more honest than the rules alone would. There's no clean verdict here, and I'm not sure the practice needs one. It just helps to know which side of it you're actually on before you build the campaign.

So should a rival's name go in your keyword list?

The rule is almost boringly simple once you separate the two halves: you can bid on competitor brand keywords in Google Ads all day, you just can't put their trademark in your copy. Everything else is economics: a higher CPC, a lower Quality Score, a conversion rate you have to earn back with genuine differentiation, and a rival who may decide to return fire.

So the real question was never "is this allowed?" It's "is it worth what it costs, and can I take the counterpunch?" Worth knowing, too: it's never been easier to see who's already bidding on your name and exactly what their ad says, which means before you decide to bid back, you can read the whole board first. Conquesting was always a two-way street; the only thing that changed is that both lanes are now lit.
