Trademark Keywords in the App Store: Rules and Risks

Trademark Keywords in the App Store: Rules and Risks

Short answer: you should not put another company’s trademark in your app’s metadata, and you should treat brand terms in paid ads as a separate, riskier question. Apple prohibits unauthorized trademarked terms in keyword metadata. Google Play can suspend apps that infringe a trademark. Ads follow different platform rules, and the law varies by country. This guide explains where each line sits, how to check a term before you use it, and how to win the same searches without borrowing someone else’s brand.

TL;DR

• Apple’s guidelines say not to pack metadata with trademarked terms, popular app names, or irrelevant phrases. Apple may modify keywords or take other action against abuse.
• Google Play prohibits apps that use an identical or confusingly similar mark without authorization, and violating apps may be suspended.
• Ads are a different system. Google Ads does not restrict trademarks as keywords, but it restricts how they appear in ad text. Apple says it will not investigate claims about brand terms used as Search Ads keywords.
• Legal exposure depends on the country. Courts in Brazil and the EU have weighed these cases differently, so a tactic that is tolerated in one market can be actionable in another.
• Before you use any term, search the USPTO database, then build your keyword list from accurate descriptions of what your app does.

What a trademark keyword means in the App Store

A trademark keyword is a brand name, product name, slogan or logo-related term that belongs to someone else, used as a search term attached to your app. It shows up in two places:

1. Organic metadata. Your app title, subtitle, the hidden iOS keyword field, and your Google Play title, short description and long description.
2. Paid search. The keywords you bid on in Apple Ads or the search terms you target in Google Ads app campaigns.

The temptation is obvious. People who type a competitor’s name into the store are showing strong intent, and a ranking for that name looks like a shortcut. Apple’s own advertising guidance acknowledges that customers may search for an app name or brand, and that keywords determine how ads are matched to those searches. That is exactly why brand terms are contested ground.

The rules differ sharply between organic and paid, so treat them separately.

Apple App Store: organic metadata rules

Apple’s developer documentation describes keywords as terms that help determine where your app appears in search, and it specifically prohibits unauthorized use of trademarked terms, competing app names and other protected words or phrases in keyword metadata.

The App Review Guidelines say the same thing from the enforcement side. Under section 2.3.7, developers must assign keywords that accurately describe the app, and must not pack metadata with trademarked terms, popular app names, or irrelevant phrases to manipulate visibility. Apple may modify inappropriate keywords or take other measures against abuse.

In practice, that means three things for your listing:

• The keyword field is not a place for rival names. Typing a competitor’s brand into your 100-character field is the clearest example of what the guideline targets.
• Accuracy is the test. A keyword has to describe your app. A rival’s brand does not describe your app, even if the two apps are similar.
• Consequences range from quiet to severe. Apple may simply edit or remove keywords, but it can also reject an update or take other action. You lose release time at best and standing at worst.

There is also a legitimate gray area: referring to a platform or technology your app genuinely works with, for example a service you integrate. That depends on whether the use is accurate and permitted by the mark owner, so check the owner’s brand guidelines and, when in doubt, ask. Do not assume that compatibility gives you a free pass to use the name in a keyword field.

Google Play: title, descriptions and the infringement policy

Google Play has no hidden keyword field. It indexes visible text such as your title and descriptions, so a trademark in your listing is visible to everyone, including the mark owner.

Google’s policy is direct: Play prohibits apps that infringe trademarks, including unauthorized use of an identical or similar mark that is likely to confuse users about a product’s source. Apps that do so may be suspended.

Two practical points follow:

• Visible text carries more risk. On Play, a rival’s name in your description is something a reviewer or rights holder can read in seconds.
• Owners are encouraged to contact you first. Google Play encourages trademark owners to contact the developer directly to resolve a concern before submitting a complaint. If you get such a message, treat it as a window to fix the listing, not as noise.

Paid search: brand terms as ad keywords

Ads sit under a different regime, and this is where most confusion starts.

Apple Ads. Apple’s legal pages state that it will not investigate claims about brand terms used as Search Ads keywords. That is a statement about Apple’s process, not a legal clearance. The mark owner can still pursue you directly, and Apple’s position does not bind a court.

Google Ads. Google’s trademark policy says that Google Ads and Display & Video 360 do not restrict trademarks used as keywords, but they do restrict their use in ads from direct competitors, or in confusing, deceptive or misleading ways. So bidding on a term is one thing. Putting a rival’s mark in your ad copy in a way that suggests affiliation is another.

Relevance also works against you commercially. Apple Ads guidance notes that an ad may be unlikely to win an auction for an irrelevant term, and it recommends combining general keywords with specific ones that describe your app more narrowly, which can improve the ad-tap-to-install rate. Brand searchers typed a name because they want that app. Many will not install yours, so conquest campaigns often cost more per install than descriptive ones.

Defending your own brand in ads

The mirror image matters too. If your brand is a keyword that rivals can bid on, you may want to bid on it yourself. Brand-defense campaigns keep your own name from being taken by a competitor’s ad. Since Apple declines to investigate keyword-use claims, defending the placement with your own bid is usually faster than filing a dispute.

How the law treats trademark keywords, country by country

Platform policy is only one layer. A rights holder can also go to court, and the outcome depends on where.

Brazil. In 2023, Brazil’s Superior Court of Justice held that using a competitor’s brand as a keyword to send consumers to a competitor’s link is a fraudulent means of diverting clientele that allows parasitic competition and confuses consumers. The court also said a search provider’s marketing of sponsored links may promote parasitic competition, and it rejected the defendants’ reliance on the limited-liability rule of the Internet Civil Framework. If you publish in Brazil, bidding on a rival’s name is a real legal risk, not just a policy risk.

If you want a plain explanation of what competitive keywords are and why rivals compete over them, this overview of competitive keywords explained is a good companion read.

European Union. The Court of Justice of the European Union has historically balanced the protection of registered marks against comparative advertising. An academic review of the case law notes that trademark owners cannot prevent third-party use that meets the criteria for permitted comparative advertising. The same paper proposes licensing models that could balance the interests of trademark holders, advertisers and consumers. The takeaway is not that anything goes in Europe. It is that the test turns on whether your use is honest comparison or confusion about who is behind the product.

United States. The USPTO frames trademark risk around likelihood of confusion, which is assessed by similarity of the marks and by whether the goods or services are related. We cover how to run that check below.

Because these rules diverge, a global app should not assume that one market’s tolerance applies elsewhere. If you target several countries, apply the strictest standard to your listing text and make ad decisions market by market.

Compare the risk by placement

The pattern is consistent: the more visible and permanent the use, the less room you have.

How to check whether a term is a registered trademark

Before a term goes into any field, run a quick clearance. The USPTO’s guidance on federal trademark searching gives a workable sequence:

1. Start with the exact wording. Search the term as you plan to use it.
2. Expand to variants. Try similar wording, alternative spellings and pronunciations. A near-match can still cause confusion.
3. Check the goods and services. Risk depends on whether the registered mark covers goods or services related to yours. A mark for software or mobile apps is much closer to your use than one for an unrelated industry.
4. Check the status. Only live marks are a concern in the same way. A dead or abandoned record carries a different risk.
5. Weigh similarity. The USPTO looks at appearance, sound, meaning and overall commercial impression.

The USPTO also suggests considering an attorney for a clearance search. For a core brand decision, such as your app’s name, that is money well spent. For routine keyword work, the five steps above will catch most obvious problems.

For apps sold outside the US, search the relevant national or regional register as well. Directories of trademark databases list WIPO’s Global Brand Database and Madrid Monitor, EUIPO’s eSearch, and national offices such as Brazil’s INPI. A clean US result says nothing about a mark registered in Brazil or the EU.

Our perspective on brand keywords

We build ASO tooling for a living, and the pattern we see is that brand keywords look like a shortcut and behave like a trap. The searches are real, but the intent belongs to someone else’s app. A user who types a rival’s name wants that app. Your listing can catch their eye, but it rarely wins the install, and your conversion rate and ad efficiency often suffer for it.

The bigger issue is where your effort goes. A keyword field is 100 characters. Every character spent on a name Apple may strip is a character not spent on a descriptive term that brings in people who are open to switching. Competitor intelligence is valuable, but its job is to show you which descriptive terms and features your rivals rank for, not to hand you their brand to borrow.

So we recommend using competitor data as research and keeping the names out of your metadata. Study which generic terms rivals rank for, what their listings emphasize and where their gaps are, then build your own listing around accurate descriptions of your features. That approach compounds over time, because you are building ranking assets that no one can take down with a complaint.

Win the same searches without borrowing a brand

Apple’s advice for choosing keywords is a good rulebook: pick accurate, specific terms based on words people may use to find an app like yours, describe its features and functionality, and avoid overly broad or irrelevant terms, duplicates, filler words and unauthorized protected terms.

Here is how that works in practice.

Describe the job, not the competitor

Someone searching for a rival expense tracker probably wants to track expenses. Terms like expense tracker, receipt scanner or budget planner capture that intent without naming anyone. Write down the five to ten jobs your app does and turn each into the phrases a user would type.

Mine competitors for generic terms

Look at which non-brand terms rivals rank for. Strip out the brand names, keep the descriptive phrases and test those you can honestly claim. Our competitor intelligence view is built for this: it shows what rivals rank for and how their listings are positioned, so you can find the gaps in descriptive keywords rather than chase their names.

Combine broad and specific terms

Following Apple Ads guidance, mix general terms that reach a wider but more competitive audience with specific terms that narrowly describe your app. In organic metadata the same logic applies: one or two head terms for reach, several long-tail phrases that you can realistically rank for.

Use every character on purpose

On iOS, the 100-character keyword field rewards discipline: no duplicates of words already in your title or subtitle, no filler, no spaces after commas. A word-frequency check on your own listing shows what you are repeating and what you are missing. Our free ASO tools include a scanner and word frequency tool for exactly this.

Check in different locales

On iOS, localized metadata can carry additional keywords for other storefronts. Do your trademark check per market before localizing, since a term that is free in one country may be registered in another.

Where Apptenium fits

Apptenium puts ASO scanning, keyword tracking, competitor intelligence and AI-powered listing recommendations in one place, so you can find descriptive keywords, see where you rank and get copy-ready fixes from each scan. It also connects performance data from sources such as Firebase and Google Analytics, so you can see whether a metadata change moved installs.

The Free plan gives you a limited number of scans per month, which is enough to audit one listing for risky or wasted terms. Pro is $9.99 per month and adds unlimited scans and premium features. See the pricing page for the current plan details, or look at our full set of ASO tools for App Store and Google Play.

What to do after a complaint, rejection or disapproval

If a rights holder, a reviewer or an ad platform flags your use of a mark, move quickly and keep it simple.

1. Read the notice closely. Identify exactly which term, field and market it concerns.
2. Remove the term everywhere. Check the title, subtitle, keyword field, descriptions, screenshots and ad groups, in every locale. Fixing one field and leaving the rest invites a second notice.
3. Respond to the owner if invited. Google Play encourages owners to contact developers directly first, so a short, factual reply that confirms the fix can end the matter before a formal complaint.
4. Replace, don’t just delete. Fill the freed space with accurate descriptive terms so you do not lose ranking coverage.
5. Escalate to counsel for serious claims. If you receive a demand letter or a claim tied to a specific country, talk to a trademark attorney in that jurisdiction. Platform policies will not protect you in court.
6. Log what you changed. Keep a record of the date and the fix. It helps if the question returns.

For ad disapprovals tied to misleading use of a mark in ad text, rewrite the copy so it describes your own app and makes no suggestion of affiliation.

A short pre-publish checklist

• Does every keyword accurately describe my app?
• Have I removed rival app names and popular app names from all fields?
• Did I search the USPTO database for the exact wording and close variants?
• Have I checked the registers of each country I target?
• Do my ad texts avoid using another company’s mark in a way that implies a link?
• Have I replaced any removed terms with descriptive alternatives?

FAQ

Can I use a competitor’s name as a keyword in my app listing?

No, not safely. Apple prohibits unauthorized trademarked terms and competing app names in keyword metadata, and Google Play can suspend apps that use a confusingly similar mark. Describe what your app does instead.

Can I bid on a competitor’s brand in Apple Ads or Google Ads?

The platforms treat this more loosely than organic metadata. Apple says it will not investigate claims about brand terms used as Search Ads keywords, and Google does not restrict trademarks as keywords, though it restricts them in ad text. The mark owner can still act under local law, and courts such as Brazil’s have ruled against the practice, so check the rules in each country you target.

How do I find out if a keyword is trademarked?

Search the USPTO’s federal trademark database for the exact term, then for similar spellings and pronunciations. Check whether the mark covers goods or services related to yours and whether it is live. For other countries, use the national or regional register, and consider an attorney for important decisions.

What should I do if I receive a trademark complaint?

Remove the term from every field and locale, then reply to the owner if they have contacted you directly. Google Play encourages owners to reach out to developers first, so a quick fix can close the issue. If you get a formal legal demand, consult a trademark attorney in the relevant country.
