App store metadata has become a critical input to modern mobile growth analytics. Keyword rankings, category charts, ratings and reviews, creative assets, and competitive positioning all live primarily inside the Apple App Store and Google Play Store ecosystems. While App Store Optimization (ASO) platforms such as AppTweak expose much of this data through specialized APIs, many growth teams also rely on flexible web scraping APIs to enrich, customize, or complement this data for bespoke analytics and internal modeling workflows.
