Quick ASO tips

  • On the App Store, write each word only once across the name, subtitle and keyword field; Apple combines them for you.
  • You usually don't need separate singular/plural forms or common spelling variants; use the space for a new word.
  • On Google Play, use keywords in natural sentences; repeating a word doesn't raise your rank and can trigger a policy warning.
  • Measure first: compare your rank before and after a change with the Keyword Rank Checker.
