Google Play keyword rank checker, in practice
Google Play has no keyword API and publishes no search volume, so most Play keyword tools estimate. aso.best does the one thing that does not need an estimate: it reads the search page for the phrase in the country you pick, exactly as a person would see it, and records the apps in order with their names, developers and star ratings. For the top ten it then reads each app's page for the rating count and the installs bucket Google prints there.
From those ten rating counts comes a difficulty on the same log scale we use for the App Store, plus a separate top-three strength. That matters when the same app ships on both stores: a phrase that is hard on iOS and easy on Play, or the other way round, changes where you spend your title characters first. Every Play page links to the same phrase on the App Store, and the assistant can read both in one question.
If you give your package id, your row is highlighted and your position is shown as a number, or as "not on the page" if you are not in the first thirty. Reads are paced and cached, a search a day and an app page a week, so repeat checks are instant. Tracking Play positions daily, the way My keywords does for the App Store, is next.
