Can I block competitor bidding on my brand name?

Not through the keyword itself. Google's trademark complaint process restricts how a mark appears in ad text, not which terms a rival buys, and US courts have held that the purchase alone is not infringement. Registration still matters, because a complaint or legal claim rests on it. In Lerner & Rowe, the court weighed the mark's strength in the owner's favor, but that wasn't enough without evidence of confusion.

Is it different outside the United States?

It can be. Trademark law is national, and the October 2024 rulings bind only US courts. A Turkish first-instance court, for example, found that a competitor infringed registered marks by bidding on them as Google Ads keywords. That rested on a local statute covering keyword use that creates a commercial effect. If you trade in several countries, take advice in each market where the bidding appears.

Should I stop bidding on my own brand?

Not without testing, and not while a rival is active on your terms. Last-click attribution flatters brand campaigns because they sit closest to conversions that might have happened anyway, so their reported return overstates what they add. But when a competitor is present, pausing hands them the top slot above your organic listing. A holdout test run during a quiet period gives a cleaner read.

Is a Competitor Bidding on My Business Name?

A customer says a rival's ad sat above your listing when they searched your name. Or your brand cost per click has climbed with no change on your side. One search of your own name won't settle it, because ads shift by location, device and hour.

The reliable answer is in your own Google Ads account. Run a campaign on your brand terms and its Auction Insights report names the advertisers competing in those auctions. In the US, a rival's bid is usually legal: two federal appeals courts ruled in October 2024 that buying a competitor's trademark as a keyword is not, by itself, infringement. Your leverage is their ad copy and your own bid.

What are the signs in your own account?

Branded search is normally the quietest auction you run. A query for your name has one obviously relevant answer, so your ads win it cheaply and sit at the top almost every time. When someone else starts bidding, the pattern changes in ways you can read before opening any competitor tool.

Three movements on your brand campaign are worth watching together:

Average cost per click rises. You are now paying to beat a real competing bid.
Search lost impression share (rank) climbs. Your ad is losing auctions it used to win outright.
Click-through rate slips. Another ad above or beside yours is taking some of the people who searched for you.

Each of these has other explanations: seasonality, a change you made, or a reseller or affiliate promoting your products. All three moving in the same week is a strong hint that the auction has a new participant.

There is a catch. If you don't bid on your own name, none of these signals exist. The rival's ad appears above your organic listing, and the only symptom is a softer organic click-through rate that is hard to pin on anyone. A brand campaign defends your name, and it is also how you detect a rival on it.

How do you confirm who is bidding?

Start with Auction Insights. Filter it to your brand campaign or brand ad group and it lists the other advertisers appearing in those same auctions. Three columns matter here. Impression share is the first. Overlap rate shows how often their ad appeared alongside yours. Outranking share shows how often yours ranked above theirs. A competitor with a rising overlap rate on your brand terms answers the question of who.

The report has limits. It needs a minimum level of activity before it populates, and it shows no keywords, bids or spend. It also tells you who entered the auction, not why. A rival running broad match on a generic term, or a Performance Max campaign, can land on a search for your name without ever adding it as a keyword. That distinction shapes your response later.

Next, confirm what the searcher actually sees. Google's Ad Preview and Diagnosis tool shows the results page for a chosen location and device without registering an impression, so checking doesn't distort your own data. Each time, record the ad text and the landing page, with the date.

Two further tools fill gaps. Google's Ads Transparency Center shows a named advertiser's creative by region and date. It searches by advertiser rather than keyword, though, so it helps only once Auction Insights has given you a name. Third-party keyword tools estimate which terms a domain buys from sampled search results. They can surface your name on a rival's list, but they miss ads targeted narrowly by location or time. None of these sends alerts, so the check has to run on a schedule.

Brand-term detection is one slice of the wider question of who is bidding against you on Google. The same reports answer it for your non-brand terms too.

Is it legal for them to bid on your name?

In the US, mostly yes. Search engines generally don't restrict which keywords advertisers can bid on, and the courts have now backed that up. In 1-800 Contacts v. Warby Parker, the Second Circuit accepted that the marks were registered and that buying them was a use in commerce. It still held that the purchase alone created no likelihood of confusion. In Lerner & Rowe v. Brown Engstrand & Shely, the Ninth Circuit reached the same conclusion because there was no evidence of actual confusion. Both rulings are summarized in a November 2024 Legal 500 article by lawyers at Buchanan Ingersoll & Rooney.

Both cases turned on confusion, and that shows you where the line is. The searcher never sees the keyword. They do see the ad text and the landing page. An ad that uses your name, or a page dressed to look like yours, is where a complaint or a claim gains traction.

Google's own process follows the same split. Its trademark policy governs how marks appear in ad text, not which keywords are bought. Policies change, so read the current version before filing.

Two conditions change the answer. Trademark law is national, so these US rulings settle nothing elsewhere. An unregistered business name also gives you far less to stand on than a registered mark. None of this is legal advice. If you believe searchers are being confused, a trademark lawyer is the next call.

What should you do once you've confirmed it?

Match the response to what the evidence shows.

If your trademark appears in their ad text, file a trademark complaint with Google and include your dated screenshots. Expect it to affect their copy, not their keyword list.

If the ad or landing page is built to look like you, take the evidence to counsel. This is the confusion question the courts turned on, and it is a legal matter, not a bidding one.

If they are simply bidding, with clean copy, compete rather than complain. Your ad is more relevant to a search for your name than theirs, which keeps your cost low and your position high, as long as you are in the auction. Write brand ads that give searchers what they came for, such as the login, the product or the location, rather than generic copy a rival can match. If they keep outranking you, the fix is usually a bid or budget change on the brand campaign. SproutMe Execute makes that kind of adjustment continuously from performance data, inside the spend limits you set, rather than waiting for a weekly review.

If they arrived through broad match or automation, a direct conversation is sometimes enough. They may not know it is happening, and adding your name as a negative keyword costs them nothing.

Whether you should then bid on their name in return is a different decision with different economics. That question is covered in should I bid on my competitors' brand names.

Conclusion

You find out whether a competitor is bidding on your business name by watching your own brand campaign, not by searching yourself once. Rising cost per click, rank-driven lost impression share and slipping click-through rate tell you something changed. Auction Insights tells you who. A dated check of the live ad tells you whether you have a policy issue, a legal issue, or simply an auction to win, which is the most common outcome.
