In the process of operation and promotion, many apps encounter the question of "How to optimize metadata for users in different countries/regions?" and so on.

Based on this, ASO World has conducted in-depth research and testing on this issue, and the analysis is mainly determined by three factors: product language, device language, and Apple ID country/region.

Product Language

Product language mainly refers to the country/region localization of the product in the App Store, i.e. the localization country set by the product in the iTC backend and each product has a primary localization language.

Device Language

The device language set by the user on the device (iPhone / iPad); (one language is selected by default in this article)

Apple ID Country

The language supported by the country/region to which the Apple ID belongs, as shown in the figure: Apple ID country/region language selection.

Language Factors Interfere with Each Other

In the App Store and App name rendering process, the three language influencing factors are interlocking and the display results will vary depending on their influence.

• If the device language, Apple ID country support language, and product language are the same

 

If the device language, Apple ID country language and product language are the same, and the product language does not include the language supported by both, the product displays the App Store and App name in the current device language and the App's primary localization language.

 

• If the device language, Apple ID country language and product language are the same, the product will display the App Store and App name in the current device language.

 

Although the language of the device and the country where the Apple ID is located may not match, since the language supported by the country where the Apple ID is located is the same as the language of the device, the product will display the App Store and App name in the current device language when the language of the product includes the language supported by both.

 

• The country where the Apple ID is located will be inconsistent

 

Although the language of the device and the country where the Apple ID is located may not match, because the language supported by the country where the Apple ID is located is the same as the language of the device, the product displays the App Store and App name in the current device language when the product language includes the language supported by both.

 

• When the language of the device and the language of the country where the Apple ID is located do not match, and the product language includes the language of the country where the Apple ID is located

 

When it is confirmed that the device language and the language supported by the country where the Apple ID is located must not be the same, and the product language includes the language supported by the country where the Apple ID is located, the product displays the App Store and App name for the country where the Apple ID is currently located (in order of preference)

 

App metadata in the App Store is rendered independent of the network environment

For the product, the optimization of the App title, subtitle, text information in screenshots, promotional text and descriptions is determined by the main target users of the App in the respective country/region.

Therefore, some of the keywords are suggested to consider whether there are target users in the corresponding country, and thus decide whether to add the target keywords in the keywords.
