FAQ
Keyword field questions answered
How many characters does the App Store keyword field allow?
The App Store keyword field allows exactly 100 characters including commas. Aso fills this field completely with relevant, non-duplicate keywords to maximize your search coverage.
Should I repeat keywords from my title in the keyword field?
No. Keywords already in your title are automatically indexed, so repeating them in the keyword field wastes precious characters. Aso avoids this automatically.
How does Aso choose which keywords to include?
Aso selects keywords based on relevance to your app's core functionality and target users. It prioritizes terms that real users search for when looking for apps like yours.
Should I use spaces or commas between keywords?
Use commas, not spaces. Spaces count as characters and waste your 100-character limit. Aso formats keywords correctly by default.
Is Aso free to download?
