iOS: where keywords come from
- App name (30 characters) — the strongest signal.
- Subtitle (30 characters).
- Keyword field (100 characters) — only visible to you, set per localization in App Store Connect.
Tips for the keyword field: separate terms with commas and no spaces, don't repeat words already in the name or subtitle, and use singular forms. Promotional text is not indexed for search.
Google Play: where keywords come from
There is no keyword field. Google indexes the title (30 characters), short description (80 characters) and full description (4,000 characters). Write naturally and mention important terms a few times — keyword stuffing is against Play policy.
Finding keywords
- Search suggestions in the stores themselves.
- Words users use in app reviews — they describe your app in their own language.
- Terms competitors rank for — see competitor app analysis.
Example
A budget app called "Pennywise – Budget Planner" uses its keyword field for "expense,tracker,money,saving,bills,finance,spending" — words not already in its name.
