- Definition
- Trademark bidding is using a trademarked term as a keyword, or in ad text, to show ads on searches for that mark.
In plain words
A trademark is a protected brand name. Trademark bidding covers two different things: choosing the mark as a keyword so an ad can show when people search for it, and writing the mark into the ad itself.
Platforms treat those two uses differently, which is why the term confuses so many people.
Why it matters for brand and paid search teams
Legal and brand protection teams need to know which use they are looking at before they decide what to do. A competitor's ad that simply appears on a brand search raises a different question from an ad whose headline uses the brand's name.
PPC teams feel the effect in cost: more advertisers on the brand's own name can mean higher prices for the brand's campaigns. Agencies often have to explain the difference to clients who expect every such ad to be removable.
How it works
Google's trademarks policy says Google does not restrict the use of trademarks as keywords. It may restrict a trademark in ad text after the owner submits a complaint, with exceptions such as resellers and informational sites whose landing pages meet the conditions it describes. Complaints are accepted for the countries where the owner shows rights.
Microsoft Advertising describes its intellectual property policies and offers a complaint form that asks for the search query, the ad title and text, and the display URL of the ad being reported.
Keyword match types add another layer: an advertiser can reach a brand search through a related keyword, so an ad on the search does not show that the mark itself was bought.
Example
An ad from summit-outdoors.example appears on the search northstar jackets in Seattle with the headline "Jackets from $49". A second ad from a different domain reads "Northstar jackets 60% off" and links to a page that sells other brands.
The first ad only appears on the search. The second uses the mark in its ad text, so that is the one Northstar's legal team reviews against the policy and its own records.
Fictional brands and domains, for illustration only.
Common mistakes and misconceptions
Google blocks competitors from bidding on my trademark. Google's policy does not restrict trademarks as keywords. The restrictions it describes apply to ad text, after a complaint.
A complaint covers every country. Google accepts complaints for the countries where the owner shows trademark rights, so coverage follows those rights.
An observed ad proves the keyword was purchased. The advertiser's keyword list is private. What you can record is the search, the ad and its context.
How to monitor it in Ads Lighthouse
Ads Lighthouse highlights ads from domains you do not own whose title or description mentions your brand, and groups them under the Mentions your brand segment, so ads that use your name in their text are easy to review.
A Brand mention to review alert can notify you by email, Slack or webhook. For Google ads that mention your brand, an AI-assisted policy review offers a first read against Google's trademark and misrepresentation policies; it is decision support, not a Google decision or legal advice.
An observation does not prove that a trademark was bought as a keyword or that a policy was broken.
Frequently asked questions
Can I stop competitors from bidding on my brand name?
Platform policies generally allow trademarks as keywords. Some companies agree on mutual limits with competitors or partners, but that is a contract between them, not a platform setting.
What should a trademark complaint include?
Each platform lists what it needs. Microsoft's form, for example, asks for the search query, the ad title and text, and the display URL. Save those details with the date and place of each search.
Does monitoring replace legal advice?
No. Monitoring gives you dated, specific examples. Whether they infringe a right depends on the law and the facts, which a qualified adviser should assess.
