Guides

5How search works and what to do about it.

Most of these start from an app

Search one on the homepage or open it from the apps directory, and every per-app view (rank history, keyword rankings, reviews, ads and the ASO change timeline) opens already loaded with it. If you only have a seed word rather than an app, the keyword suggestion tool expands it against Apple's own autocomplete.

Free, and most of it works without an account. New to this, or want the reasoning behind the fields? Start with the ASO guide and the ASO checklist.
