All toolsKeyword space calculator
Check the length of your listing fields and review repeated terms, spacing and room for additional keywords.

Counts use UTF-16 text lengths, which may differ from visible characters or bytes. This matters for emoji, combined accents, and non-Latin text. The estimate is a drafting aid; check each field in the store console. Suggested savings may overlap.
Apple allows 30 characters for the name and 30 for the subtitle. Its keyword documentation differs between 100 characters and 100 bytes. This tool uses a 100-character drafting allowance; validate the final localized text in App Store Connect. Filling every field does not guarantee indexing or better rankings.
Write for the audiences you support
Choose languages from your audience and storefront data. AppDrift’s AI metadata translation helps prepare localized drafts. Have a fluent reviewer check their meaning and validate the final fields in the store. Additional locales do not guarantee extra rankings.

What the field allowances tell you
Apple identifies the name, subtitle, keywords, categories, and user behavior among its search factors. Field lengths do not reveal ranking weights or an exact indexed-character total. Apple recommends avoiding repeated metadata terms and spaces after commas; spaces within keyword phrases are allowed. Read Apple’s search guidance and our sourced character-limit reference for the documented limits and the keyword-unit discrepancy.
What to review after shortening a draft
Consider relevant terms that describe the app. A candidate’s difficulty score is a diagnostic estimate. Check your current position in the intended storefront with the rank checker, then keep a baseline before changing metadata. AppDrift’s keyword tracking records changes over time so you can review the results.
Google Play has a name (30 characters), short description (80), and full description (4,000), with no dedicated keyword field in the main listing. Use the keyword density checker to review repetition in a long description, not to target a supposed ideal keyword density.
Frequently asked questions
What limits does this keyword calculator use?
It compares draft lengths with 30 for the name, 30 for the subtitle, and 100 for keywords. These are field allowances, not an indexed-character budget. Apple search guidance says 100 characters for keywords while the Connect reference says 100 bytes. This browser uses UTF-16 text lengths, so validate localized text in App Store Connect.
Should I put spaces after commas in the App Store keyword field?
Apple recommends commas without spaces after them. Spaces within keyword phrases are allowed, such as mood tracker. With 20 comma-separated terms, removing one space after each comma saves 19 characters.
Should I repeat my title words in the keyword field?
Apple recommends avoiding words already included in the app name, subtitle, or category. Review suggestions in context; this calculator does not measure the ranking effect of a repeated word.
Does Google Play have a keyword field?
Google Play has no dedicated keyword field in its main store listing. It allows a 30-character name, an 80-character short description, and a 4,000-character full description. Write accurate, readable copy and avoid irrelevant or repetitive keywords.
Should I localize just to add keyword space?
Choose localizations for audiences your app can support, and have a fluent reviewer check the copy. This calculator does not verify cross-localization indexing or promise additional search coverage from filling more locales.
