A competitor bidding on your brand keywords in Google Ads is allowed, it is common, and Google will not stop them. That is the short answer, and most of the advice on this topic stops there, which leaves you with the wrong question.
The right question is not whether they can. It is what their presence is actually costing you, and that number is specific to your business rather than to the practice in general. The most cited study on this subject found brand ads were worth essentially nothing. It was run at a company in a situation almost nobody reading this is in.
So: what the policy actually permits, what Google will act on, how to measure your own exposure rather than borrowing someone else's conclusion, and an escalation ladder that starts with the cheapest move rather than the loudest one.
They are allowed to, and Google will not stop them
Using a trademark as a keyword is not a policy violation. Google says so directly.
Google's trademarks policy states that Google will not restrict the use of trademarks as keywords. Keyword use is explicitly outside what the trademark complaint process covers. You can file, and Google will not act on the bidding itself.
This is worth internalizing before you spend a week on it. Every "make them stop" plan that targets the keyword rather than the ad text runs into the same wall. The bidding is not the actionable part.
If you want the view from the other side of this, we wrote about bidding on competitor brand terms as an offensive tactic, including when it is worth doing and when it just annoys people with money.
What Google will act on is your name in their ad text
Ad text is a different matter, and this is where a complaint has teeth.
The same policy restricts using trademarks in an ad from a direct competitor, and ads that use the trademark in a confusing, deceptive or misleading way. The distinction that matters: the trademark must appear in the ad itself, not only on the landing page, for Google to consider it.
Two exceptions are written into the policy and they catch people out:
Which means a review site or comparison page running "Best [Your Brand] Alternatives" is frequently within policy, and a straight competitor putting your name in a headline usually is not.
One procedural detail worth knowing before you file: Google accepts complaints against specific advertisers identified by their URLs, within the countries and industries where the trademark owner has demonstrated rights. It is not a blanket takedown. You are naming a specific advertiser in a specific market, and you will need to do it again for the next one.

The study everyone quotes was run in conditions you do not have
Somebody in this conversation will eventually say that brand advertising is proven worthless. They are referring to a real and very good experiment, and it does not describe your situation.
eBay halted paid search on its own brand terms across regions and measured what happened. The finding, in the authors' words from Blake, Nosko and Tadelis: "almost all (99.5 percent) of the forgone click traffic from turning off brand keyword paid search was immediately captured by natural search traffic." Elsewhere they put it plainly: brand-keyword ads had no measurable short-term benefit.
Now look at the conditions. eBay was one of the most recognized brands on the internet. It held the top organic result for its own name. And critically for this article, it had essentially nobody bidding against it on that term.
That last condition is the entire subject of this post. When a competitor occupies the paid slot above your organic listing, the traffic you would have retained for free is no longer sitting there unguarded. The mechanism the eBay result depends on is exactly the mechanism a competitor breaks.
Two yellow directional arrow signs on a wooden post pointing in opposite directions.
A later replication makes the point from the other direction. On Edmunds.com, a far smaller brand, a later replication found roughly half the traffic arriving through branded search ads would not have arrived through organic links alone.
Two careful experiments, opposite practical conclusions, because they measured brands of very different strength. Which is the actual lesson: anyone who tells you the answer without testing your account is guessing. That goes for the agency recommending a large brand-defense budget and equally for the consultant telling you to switch it off. Confident answers to a company-specific question are the red flag here.

Find out what your brand traffic is actually worth
Brand bidding is one of the easiest things in paid search to test properly, which makes it strange how rarely anyone does.
Run a geographic holdout. Pause brand campaigns in a representative subset of regions, leave them running everywhere else, and compare total conversions, not paid conversions, between the two groups over a few weeks.
Total is the word doing the work. Paid conversions will obviously fall in the paused regions. The question is whether *total* conversions fall, or whether organic simply absorbed them. If total holds steady, your brand spend is buying traffic you already had. If total drops, you now know the size of the leak and what defending is worth.
A few things that make the test honest:
Do this once and the annual argument about brand spend stops being an argument.
Four-step flow for running a geographic holdout test on brand campaigns: split matched regions, pause brand in one group, wait a full sales cycle, then compare total conversions rather than paid conversions.
The escalation ladder, cheapest first
Work down this list in order. Most situations resolve in the first two steps, and the expensive options are rarely the ones that work.
1. Confirm it is actually happening. Ad previews, not your own repeated searches, which distort your data and your impression share. Check on different days and locations, because many competitor campaigns run in bursts rather than continuously. There is a method in our guide to checking competitor ads.
2. Make sure your own brand campaign exists and is healthy. A defended brand term is cheap and hard to outrank. Your own brand keywords carry the highest relevance scores in your account, so you can usually hold the top slot at a fraction of what the competitor is paying.
3. Check their ad text. If your name is in their headline or description and they are a direct competitor without a reseller or informational defense, file the trademark complaint. This is the one lever Google will actually pull.
4. Contact them. Underrated and frequently effective, particularly with smaller companies who set this up without much thought. A polite note pointing out that you will reciprocate is often enough. It costs nothing and it resolves faster than any other option.
5. Reciprocate, deliberately. Bidding on their brand as a bargaining chip is a real option and a real cost. Enter it as a negotiating position with a defined end, not as a permanent line item, because two companies paying to appear on each other's brand terms is a transfer from both of them to Google.
6. Legal action. Expensive, slow, and rarely proportionate unless there is genuine consumer confusion or the competitor is impersonating you. Trademark law varies by jurisdiction and this is where you want an actual lawyer rather than an article.
Six numbered steps for responding to a competitor bidding on your brand, from confirming it is happening through to legal action as the last resort.
What a defended brand campaign looks like
Keep it separate, keep it exact, and stop it competing with itself.
Give brand terms their own campaign so the reporting stays honest. Blending brand into a general search campaign is how accounts produce spectacular return figures that mean nothing, because brand conversions get credited to work that did not produce them.
Then:
Multi-location and franchise systems are the most exposed to this of any business model, because the brand is valuable and defending it is nobody's specific job. We covered the governance side in franchise Google Ads.
When the right move is to do nothing
Sometimes the correct response to a competitor on your brand term is to note it and move on. This is not the advice most agencies give, because doing nothing is difficult to bill for.
Do nothing when:
The failure mode worth avoiding is spending a quarter and a meaningful budget defending against something that was costing you very little, while the actual problem was that not enough people search your name at all.

FAQs
Is it legal for competitors to bid on my brand name in Google Ads?
Using a trademark as a keyword is permitted under Google's policy, and Google explicitly does not restrict it. Trademark law is separate from platform policy and varies by jurisdiction, but in most cases keyword bidding alone is not actionable. What is more often actionable is the use of your trademark inside the ad text itself.
Can I make a competitor stop bidding on my brand keywords?
Not through Google, and not on the bidding itself. Google's trademark complaint process covers use of a trademark in ad text, not use as a keyword. The practical routes are a trademark complaint if your name appears in their copy, direct contact with the company, or reciprocating as a negotiating position.
Should I bid on my own brand name?
It depends on your brand's strength and whether anyone is bidding against you, and the honest answer is that you should test it. The eBay experiment found 99.5 percent of clicks were retained without brand ads, while a replication on a much smaller brand found only about half would have arrived organically. Run a geographic holdout and measure total conversions rather than paid conversions.
How do I know if a competitor is bidding on my brand?
Use the ad preview and diagnosis tool rather than searching repeatedly yourself, which skews your impression data. Check across several days and locations, since competitor brand campaigns often run in bursts. Your own auction insights report for the brand campaign will also show which domains appear alongside you.
Will a competitor bidding on my brand raise my costs?
It can, though usually less than people expect. Your own brand keywords carry very high relevance in your account, so you can generally hold the top position at a much lower cost per click than a competitor pays to appear at all. The larger cost is usually the clicks they take, not the price increase on the ones you keep.
Should I bid on their brand name in return?
It is a legitimate option, best used deliberately and with an end point. Reciprocating gives you something to trade in a conversation, and a conversation is what usually ends these situations. Left running permanently it becomes two companies paying to appear on each other's brand terms, which benefits neither of them.
What if the competitor is a reseller or a review site?
Check the landing page before filing anything. Google's policy permits trademark use where the landing page is primarily dedicated to selling the products, or where its primary purpose is informative detail about them. A comparison page ranking for alternatives to your product is frequently within policy, which is frustrating and worth knowing before you spend time on a complaint that will be rejected.
Where this leaves you
You cannot stop a competitor bidding on your brand name. You can sometimes stop them putting it in their ad, you can hold the top slot cheaply because your own name is the most relevant keyword you will ever own, and you can find out what any of it is actually worth with a two-week geographic holdout.
Do the test before the arguing. The two best experiments on this question reached opposite practical conclusions because they studied brands of very different strength, which means the answer for your business is not in an article. It is in your own account, and it is cheap to find.
If you would rather have someone run the holdout and read the result properly, that is part of what our PPC management does, month to month, cancel anytime.
