# 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: `SKStoreReviewController` — max 3 prompts per 365 days
- Reply to all reviews, especially negative ones
- Fix issues mentioned in poor reviews before next update
