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
If you need paid advertising strategies (use marketing skills instead)
