Which Countries to Localize an App First

The countries to localize first are not “all of them,” and they are not a revenue league table you saw in a slide. You want a storefront where two things are true at once. You can support the people who install, and they search in a language your current listing does not speak. If either one is missing, a translation is a file that will disappoint someone.

Keyword work for a new language is how to localize App Store keywords. The images are App Store screenshot localization. Right-to-left storefronts are stricter than a caption swap, which right-to-left screenshots covers. Apple’s localization list includes many languages, from Japanese and German to Arabic and Hebrew. Adding the locale in App Store Connect is the easy part.

Support is the first filter

A localized listing invites mail, reviews, and refund questions in that language. If your support URL is an English inbox nobody reads, do not promise a Japanese product page. “Support” here means a person can understand the problem and reply, or you have a clear path that does not strand the user. It does not mean a machine translation of your FAQ that you have never read aloud.

The same filter applies to the product. A recipe app that only understands US cups, and has no way to show grams, will frustrate a cook who found it through a German keyword. Localize the listing after the app can be used, or localize only the metadata you can stand behind and keep the UI honest about its limits. Do not show a German screenshot of a unit toggle the build does not have.

A different search language is the second filter

English (U.S.) keywords do not compete for Japanese queries. That is the gap localization is for. English (U.K.) or English (Australia) may still be worth keyword edits, but they are not the same project as a full translation, and they do not require a new UI language if the app is already English. Do the storefront where the search language actually changes before you polish a second English dialect.

Pick one language you can finish: keywords, screenshots, description, and the in-app strings that those screenshots show. A half-localized page, with a Japanese subtitle over English screenshots of English buttons, looks abandoned. Finish one. Then look at the next language that passed both filters.

Worked example: a recipe app with an English UI

The app is in English. Recipes use cups and ounces. The developer can answer mail in English and Spanish, and has a friend who can check Japanese strings but cannot support Japanese users every week. Spain and Mexico pass the support filter. Japan fails it for now, even though Japanese search is a real gap. Germany fails it too, until support exists. That is a reason to wait, not a claim about which country earns more.

For Spanish, the work is keywords cooks actually type, screenshots with Spanish UI or at least Spanish captions on honest English UI only if you are explicit that the app is still English, and a description that does not promise gram toggles you have not shipped. If you can flip the interface to Spanish, do that before you shoot. Do not launch Arabic yet. You cannot support it, and the screenshots would need to be mirrored, not just translated.

Localize Spanish first because support exists and search is not English. Wait on Japanese and Arabic until you can help users and, for Arabic, mirror the UI.

Look at the chart, not a made-up revenue number

Before you pay for a translation, see whether the category is active in that country. Open top apps and look at the chart for the category in the country you are considering. You are checking that people browse this kind of app there, and what the listings look like. You are not collecting a revenue figure. This article will not invent one, and you should not paste one from an unsourced blog into your plan.

If the local chart is full of recipe apps with localized screenshots and yours would be the only English page, that supports doing the work once support is ready. If you cannot read the competing titles, that is another sign you are not ready to support the storefront. The chart is a qualitative check. It is not a forecast.

What day one should not include

Do not add every localization App Store Connect offers because the menu is long. Empty or machine-translated pages create reviews you cannot answer. Do not localize a country you have turned off in availability. Price and availability are separate from language. A beautiful German page does nothing if Germany is not available, and a German price does not require a German listing if you are not ready to support it.

Do not assume a soft launch in one country replaces this choice. A soft launch is a way to learn. It still needs a language you can support. Track a short list of metrics after you publish the new localization, instead of a huge dashboard. Impressions and conversion in that storefront will tell you if the page is being seen. They will not, by themselves, justify translating the next twenty languages.

Keywords and screenshots move together

A new keyword field without new screenshots ranks you, if it ranks you, into a page that still looks foreign. Do both, or do neither. For the recipe app, Spanish screenshots should show a recipe a Spanish-speaking cook recognizes, with UI in Spanish if the app has it. Captions should use the words you put in the keyword field only when they fit naturally.

Right-to-left is not a subtitle job. If you later add Arabic, plan a mirrored screenshot set and a support path before you add the localization. Hebrew is the other right-to-left language Apple lists for App Store localizations. Treat it with the same layout care, not as an English page with a translated caption.
