ASO & App Stores glossary
App Store Optimization is a weekly loop: keywords earn impressions, creatives and ratings convert them into installs. This cluster covers ASO vocabulary from keyword research and screenshot headline copy to A/B tests and store conversion rate optimization.
Cards define terms quickly for your team and for search crawlers building topical context around mobile distribution. Pillar guides focus on strategy-level topics — core ASO, keywords, screenshot testing, and conversion — with quoted notes from Sych on live store listings.
Pair these definitions with the Prompt Library for generating listing copy and screenshot headlines, then validate changes in App Store Connect and Google Play Console rather than guessing from rank checkers alone.
