App Store keywords field by locale: 5 examples
The App Store Connect keywords field holds 100 bytes (UTF-8), with keywords separated by commas. People often say “100 characters”, but that is only true for plain English letters.
- English and most Latin-script languages: about 100 characters (1 byte each; letters like ä, ç or ã take 2 bytes).
- Korean, Japanese and Chinese: 3 bytes per character, so roughly 33 characters.
- Do not waste bytes: a space after a comma costs a byte; a word already in your app name or subtitle is indexed anyway; a duplicate keyword adds nothing.
- Google Play has no keywords field. Use the words naturally in the short description (80 characters) and full description (4000 characters).
Five locales, one app
Examples for Focus Bell, a fictional demo app by Fizz Labs (not a real store listing). Each keyword string passes our free checker with 0 errors: within 100 bytes, no spaces after commas, no duplicates and no words repeated from the name or subtitle.

Byte and character counts are computed by the same rules engine as the checker (Unicode grapheme clusters for characters, UTF-8 for bytes).
