Apple limits the keyword field to 100 bytes. That is a byte limit, not always a character limit. Use commas to separate terms and keep the field focused on words that describe the app’s useful function.
Do not repeat words already in the app name or company name. Do not add another app name, a competitor brand, or a claim the app cannot support. Relevance matters more than filling every last byte.
Group duplicates, remove vague words, and validate the final string before publishing. Search demand and competition can change by storefront and language, so review the field after meaningful product changes.
Use this in your next ASO review
Turn the advice above into one small, traceable change. A simple review keeps your listing accurate and makes it easier to learn what helped.
- Open the current App Store Connect entry for your app and copy the app store keywords material you want to check.
- Compare it with the current product behavior, supported locales, and the source linked below.
- Draft one improvement, record the reason, and validate every field limit or submission rule that applies.
- Ask a person to approve the draft before it changes a live listing.
