ASO Guide: The Complete Framework
1. Keyword Research
The foundation of any ASO strategy:
| Factor | App Store | Google Play |
|---|---|---|
| Where keywords matter | Title, Subtitle, Keyword field | Title, Short desc, Long desc |
| Character limits | Title: 30, Subtitle: 30, Keywords: 100 | Title: 30, Short: 80, Long: 4000 |
| Strategy | Precise, high-weight keywords | Comprehensive, natural density |
ASO Tools for Keyword Research:

2. App Store Page Optimization
Visual Assets Checklist:
| Asset | Specifications | Tips |
|---|---|---|
| Icon | 1024x1024 px | Simple, recognizable, no text |
| Screenshots | 6.5" display size | First 2 most important |
| Preview Video | 15-30 seconds | Show core value immediately |
| Feature Graphic (Google) | 1024x500 px | High contrast, clear CTA |
3. Ratings & Reviews
Ratings directly impact:
- Search ranking

- Featured placement
Best Practices:
- Prompt for rating after positive moments (completed task, achievement)

- Never incentivize fake reviews (against ToS)
4. App Store vs Google Play Differences
| Dimension | App Store | Google Play |
|---|---|---|
| Algorithm | Metadata exact match | Text understanding + performance |
| Description | Doesn't affect ranking | Critical for ranking |
| Technical metrics | Indirect impact | Android Vitals directly affects |
| A/B Testing | Product Page Optimization | Store listing experiments |
| Review time | 24-48 hours | Few hours |

FAQ: App Store Optimization
How long does ASO take to show results?
2-4 weeks for initial ranking changes. Full optimization cycle is typically 2-3 months.
What's more important: keywords or visuals?
Keywords get you discovered; visuals convert. Both matter equally. A high-ranking app with poor screenshots won't convert.
Should I localize my app store listing?
Yes, if you're targeting international markets. Localized listings can increase downloads by 30-50% in target regions.
How often should I update keywords?
Review monthly. Update when:
- Seasonal trends change
- New competitors emerge
- Your app adds features
- Current keywords underperform
