How to prepare your app for localization

Mobile app localization is one of the most important parts of your app growth. Therefore, entering a new market is a big step for each app business. To start app localization, you need to decide which market you would like to enter, analyze its potential and threats. 

It is very important to understand that one country can have more than one language (locale). It is important to understand that locale is a combination of territory and language. In other words, it is a storefront of app stores. For example, de-AT, de-CH, en-US, en- AU, etc. For a more clear understanding here is another example: Canada has English (en-CA) and French (fr-CA) as official languages, and Belgium has even three: Dutch (nl-BE), German (de-BE), and French (fr-BE). Therefore, decide which local language you would like to target before you start the whole app localization process.

Tips: in order to get an understanding of the new market app leaders and their performance, check out App Radar’s Top Charts by category & country, Category Rankings, App Downloads, and Downloads Trends in a specific country and specific timeframe. 

Once you are done with your choices, you will need to translate your in-app experience to a new language. After that you can start to localize your app store listing with the following steps: 

  • Add new locale for your app store market
  • Find keywords in locale language
  • Localize app store listing with new language
  • Update your app store listing

The first and easiest step is to add new locales. If you do it with App Radar, it will take you a couple of minutes. You just need to go to  Store Listing Editor and add a new local to your app. After that, you are ready to start your localization process.

The next steps are considered to be more complex and time-consuming. Let’s have a simple example here. Imagine you are an Adidas app and you would like to localize your app for the Chinese market. You are checking your competitor Nike in the Chinese app market and see keywords ‘健身’ with a good search volume. However, it is hard to decide if this is keyword relevant enough for you to add it to your app metadata. 

Instead of jumping to third-party tools and checking each keyword manually one by one, you can use App Radar’s keyword auto-translation feature. Just in one click, you can see that the keyword ‘健身’ means ‘fitness’. It is definitely relevant for the Adidas app keyword, therefore, you can add it to your tracking list with confidence.

Keyword Auto-Translation for easy app localization

In order to localize your app store listing, you need to find keywords in a local language and optimize your app store listing with them. The main goal is to start ranking for specific keywords, and, as a result, increase the chances of app downloads. Remember that keyword optimization applies to the whole app store metadata that is indexed. In the case of Google Play Store, it is app name, short description, and long description. For Apple App Store, it is app name, subtitle, keyword field.

Tips: people are more likely to search in their local language and download an app if it shows in their language. In order to get visibility within new markets, you need to rank for relevant keywords in the local language. This means it's not only about translating your store listing, but also including keywords that will bring you traffic.  

There are basically 3 ways how you can find relevant keywords in other languages for your app store listing:

  • Manually translate all potential keywords that you have for your main locale
  • Have a big and international team that can natively work with keywords from different localizations 
  • Use a magic button inside ASO tool that auto-translates keywords from all languages to English
