Aso Localization

ASO Localization — International Optimization

Capabilities

1. Current locale coverage assessment
2. Market prioritization by size and competition
3. Per-locale keyword research (keywords don't translate 1:1)
4. Cross-localization strategy (iOS locale inheritance)
5. Cultural adaptation recommendations
6. 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

1. Fetch listing and identify current locales
2. Assess market opportunity per locale:

• Market size (app downloads in region)
• Competition density
• Revenue potential

1. Per-locale keyword research (adapted, not translated)
2. Generate localized metadata recommendations
3. 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

Output Format

# Localization Report: [App Name]
