How to choose App Store keywords that fit your app

Choose App Store keywords by product fit, search intent and the apps already winning the results — not by a made-up volume number alone.

Start with the customer problem, not a competitor word list

A good candidate phrase describes a job a real person expects the app to do. For a receipt scanner, “scan receipts for expenses” is a useful hypothesis; “scanner” on its own is so broad that it says almost nothing about intent. Start with the product’s core outcome, the feature names customers use, review language and autocomplete suggestions. Then group close variants by the same intent instead of collecting hundreds of disconnected words.

Check what the store actually lets you target

On the App Store, the app name and subtitle each allow up to 30 characters, while the keyword field allows up to 100 bytes. Apple also advises against repeating words already present in the app name, subtitle or category because the repetition does not add search value. That makes the keyword field a constrained allocation problem: use it for relevant concepts that your visible metadata does not already cover.

Read the result field before making a promise

Search the exact phrase in the target storefront. Look at the top results, their product promise, rating footprint and how closely they match the query. A phrase can look attractive until the results reveal that people mean a different type of app. If the winning apps solve a different job, ranking for the phrase would bring the wrong visitors even if you could get there.

Use popularity to prioritize, not to override relevance

Neither app store publishes a public monthly search-volume number. Directional demand signals can help rank several relevant candidates, but they cannot turn an irrelevant phrase into a good target. The better decision is usually the term where the app genuinely fits, the competitive field is plausible and the listing can make the same promise convincingly.
