ASO Localization — International Optimization
Capabilities
- Current locale coverage assessment
- Market prioritization by size and competition
- Per-locale keyword research (keywords don't translate 1:1)
- Cross-localization strategy (iOS locale inheritance)
- Cultural adaptation recommendations
- CJK character width considerations
Key Principle
Localization ≠ Translation. Each locale needs independent keyword research. A direct translation of English keywords often misses how users actually search in that language.
Impact: Adding a local language → up to 128% more downloads, 26% revenue increase per country.
Process
- Fetch listing and identify current locales
- Assess market opportunity per locale:
- Market size (app downloads in region)
- Competition density
- Revenue potential
- Per-locale keyword research (adapted, not translated)
- Generate localized metadata recommendations
- Identify cross-localization opportunities
Platform Locale Support
iOS
- 35+ localizations available
- Each locale: independent App Name, Subtitle, Keywords, Description, Screenshots
- Cross-localization: Apple indexes related locales (e.g., en-US → en-GB)
- Keyword field per locale: independent 100-char allocation
Android
- 75+ localizations
- Custom store listings: up to 50 per app
- Target by country OR language
- Full description indexed per locale independently
CJK Considerations (Chinese, Japanese, Korean)
- Characters convey more meaning → fewer chars needed for same concept
- Keyword density calculations differ (word segmentation)
- Character width: CJK chars take ~2x visual space
- Search behavior: shorter queries, different word boundaries
