# App Store Optimization (ASO) Optimize your app's presence on the App Store and Google Play. ## Keyword Strategy ### Research Process 1. **Brainstorm 50-100 terms** users might search 2. **Categorize**: Brand, Category, Feature, Competitor 3. **Score** each by: Volume × Relevance ÷ Competition 4. **Select top 10-15** for your listing ### App Store (iOS) - Title gets most weight — front-load primary keyword - Subtitle and keyword field get secondary weight - 100 characters max in keyword field (no spaces, comma-separated) - Don't repeat words already in title/subtitle ### Google Play - Full title (50 chars) and short description (80 chars) indexed - Long description (4000 chars) gets less weight but matters for conversions - Include keywords 3-5x naturally in long description ## Visual Optimization ### Screenshots (critical for conversion) - **1st screenshot**: Hero — show the core value prop - **Create a story** across 4-6 screenshots - **Text overlays**: 5-7 words max, high contrast - **A/B test** screenshot styles every quarter - iPhone 6.7" and iPad sizes required (App Store) ## Ratings & Reviews - Request review after positive user action (not on launch) - iOS: `SKStoreReviewC

How do I install it?

Run `npx skills add cosmicstack-labs/mercury-agent-skills --skill app-store-optimization --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From cosmicstack-labs/mercury-agent-skills, a repository with 364 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
