Questions
Where do the keyword scores come from?
They are calculated from public App Store signals, such as the apps that show up for a keyword and how strong those apps are. They are directional scores to help you compare keywords, not Apple's internal search numbers.
Does it work for Google Play?
Not yet. The keyword research is built for the iOS App Store.
Is it free?
Yes, keyword research is free during the beta and you don't need an account to use it.
What should I do with the results?
Use your strongest, most relevant keywords in the app title and subtitle, and the rest in the keyword field. Our free iOS Keyword Field Optimizer helps you fit them into 100 characters without duplicates.
