Category rank
Your app's ranking within its assigned App Store category, separate from keywords.
Category rank is your position in the top-charts list for your app's category (Health & Fitness, Productivity, etc.). Category rank is driven by recent download velocity (last 24-72 hours weighted heavily) plus your historical baseline. Reaching the top 10 of a category often means a 3-5× organic install boost from category-browsers. Category rank is more volatile than keyword rank because it's velocity-weighted — a paid acquisition campaign can push you up rapidly, and ranking falls fast when the campaign stops.
