What is rankability (keyword difficulty)?
Rankability is how realistic it is for a new app to reach the top of a store search — the gap between how much a phrase is searched and how strong its current leaders are.
A phrase searched by many, answered by a few weak apps, is easy to rank for. A phrase answered by ten household names, all updated last week, is not — however much it is searched.
SideRadar scores it from the leaders' ratings, age and update habits for each phrase, in each store and country.
