Keyword Field (iOS)
The hidden 100-character field on the App Store where you list keywords, not shown to users.
What it means
The iOS keyword field is a hidden, 100-character input where you supply keywords for indexing. Users never see it, so it’s purely for search. Best practice is comma-separated single words with no spaces, avoiding duplication of words already in your title and subtitle.
Because it’s capped at 100 characters, efficiency matters: don’t waste space on plurals the store already handles, common stop words, or your own brand/category name (which the store indexes automatically).
Frequently asked questions
How should I format the iOS keyword field?
Use single words separated by commas with no spaces (e.g. “budget,tracker,savings”). Don’t repeat words already in your title or subtitle, skip spaces to save characters, and avoid stop words.
Does Google Play have a keyword field?
No. Google Play has no hidden keyword field — it indexes keywords from your title, short description, and long description instead.
