App Storeの可視性、キーワードカバレッジ、変換率、グローバルASOパフォーマンスを向上させるためのiOS製品ページのローカライズ実践ガイド
Localizing an iOS App Store product page means more than simply translating text. It involves reshaping your metadata, creatives, and messaging to match the language, expectations, and cultural norms of each market — while remaining aligned with Apple’s technical rules.
This guide breaks down how App Store localization works, why it matters for ASO, and how developers can design high-impact, market-ready pages using data, creativity, and modern ASO workflows.
Localization for the App Store is managed through App Store Connect, where developers can set languages, add localized metadata, manage screenshots, upload previews, and monitor performance.
Although the core principles are similar to Google Play, App Store localization has its own technical rules and behavioural nuances. Understanding these differences is essential for maximizing discoverability and conversion.
Key localized elements include:
These components form the foundation of how your app is discovered and judged by users across regions.
Each App Store locale has a default language and may support additional ones. This affects how keywords are indexed and which version of your page users see.
For example:
|
ISO |
Region |
Default Language |
Additional Supported Languages |
|
USA |
United States |
English (U.S.) |
Spanish (Mexico), French, Korean, Russian, Chinese (Simplified/Traditional), and more |
|
CHN |
Mainland China |
Simplified Chinese |
English (U.K.) |
Practical implications:
This multi-index system is a powerful lever for extending organic reach.
A truly localized product page goes beyond translation and addresses:
Rewritten titles, descriptions, subtitles, and promotional text crafted for local search behavior and cultural tone.
Screenshots and preview videos redesigned to reflect:
On the App Store, screenshots heavily influence conversions — more so than on Google Play — making them a high-priority asset during localization.
Localization should match the in-app experience. When your UI, onboarding, and store page speak the same language and tone, conversion and review quality rise significantly.
While many principles are shared, two major factors differentiate the App Store:
iOS and Android audiences behave differently in certain regions. These behavioural patterns shape how users interact with page elements, especially visuals.
The App Store’s layout places more emphasis on screenshots and less on long descriptions. This changes how localization should be prioritized.
For best results, your iOS localization strategy should be independent — not copied from Google Play.
Investing in a localized product page can deliver strong, measurable improvements:
For ASO practitioners, localization is one of the most reliable levers for compounding organic growth.

Because user behaviour differs from Google Play, treat iOS as its own ecosystem and adapt creative choices accordingly.

Visuals drive first impressions on iOS. Prioritize image-heavy assets and adapt messaging density and layout for cultural preferences.
Regional holidays such as Golden Week in Japan or Lunar New Year in China significantly shift user behaviour and should influence metadata updates.
User feedback reveals natural language patterns and identifies misunderstandings in your positioning.
Take advantage of Apple’s extended indexing rules to unlock additional keyword space.
Start simple, then progressively deepen cultural relevance based on performance insights.
Localization is iterative — and the best results come from ongoing experimentation.
