Best Practices
Keyword Research
- Volume vs. Competition : Balance high-volume keywords with achievable rankings
- Relevance First : Only target keywords genuinely relevant to your app
- Long-Tail Strategy : Include 3-4 word phrases with lower competition
- Continuous Research : Keyword trends change—research quarterly
- Competitor Keywords : Don't copy blindly; ensure relevance to your features
Metadata Optimization
- Front-Load Keywords : Place most important keywords early in title/description
- Natural Language : Write for humans first, SEO second
- Feature Benefits : Focus on user benefits, not just features
- A/B Test Everything : Test titles, descriptions, screenshots systematically
- Update Regularly : Refresh metadata every major update
- Character Limits : Use every character—don't waste valuable space
- Apple Keyword Field : No plurals, duplicates, or spaces between commas
Visual Assets
- Icon : Must be recognizable at small sizes (60x60px)
- Screenshots : First 2-3 are critical—most users don't scroll
- Captions : Use screenshot captions to tell your value story
- Consistency : Match visual style to app design
- A/B Test Icons : Icon is the single most important visual element
Reviews & Ratings

Limitations
Data Dependencies
- Keyword search volume estimates are approximate (no official data from Apple/Google)
- Competitor data may be incomplete for private apps
- Review analysis limited to public reviews (can't access private feedback)
- Historical data may not be available for new apps
Platform Constraints
- Apple App Store keyword changes require app submission (except Promotional Text)
- Google Play Store metadata changes take 1-2 hours to index
- A/B testing requires significant traffic for statistical significance
- Store algorithms are proprietary and change without notice
Industry Variability
- ASO benchmarks vary significantly by category (games vs. utilities)
- Seasonality affects different categories differently
- Geographic markets have different competitive landscapes
- Cultural preferences impact what works in different countries
Scope Boundaries
- Does not include paid user acquisition strategies (Apple Search Ads, Google Ads)
- Does not cover app development or UI/UX optimization
- Does not include app analytics implementation (use Firebase, Mixpanel, etc.)
- Does not handle app submission technical issues (provisioning profiles, certificates)
When NOT to Use This Skill
- For web apps (different SEO strategies apply)
- For enterprise apps not in public stores
- For apps in beta/TestFlight only
