Frequently asked questions

How does Asonix measure keyword popularity?

Where Apple Ads runs, Asonix shows Apple’s own popularity score. Where Apple only returns its minimum of 5, and in the 84 countries without Apple Ads, it shows an Asonix estimate. That covers all 175 App Store countries.

How often do rankings update?

Every day, in every country you track. Asonix checks them on its own servers, so the data is ready when you open it.

What do I do with the keywords I find?

Put your strongest keywords in your app’s name, subtitle and keyword field, where they count most for search. Track them, ship your update, and watch which rankings move. Keep what works and replace what doesn’t with each release.

Do I need to connect App Store Connect?

No. Asonix works from public App Store data. You sign in with Google and add any app, your own or a competitor’s, without giving Asonix access to your developer account.
