Field Entry


Apple keyword field tips:
  • Use commas without spaces between keywords (saves characters)
  • Don’t repeat words already in your title or subtitle
  • Don’t include your app name or brand
  • Singular vs plural: Apple matches both, so pick the shorter form
  • Use all 100 characters — every unused character is a wasted opportunity
Keyword stuffing will get your app rejected or penalized. Apple and Google both have guidelines against unnatural keyword repetition. The keywordStuffingDetected flag warns you when a word appears too frequently (> 5% density in descriptions).
