10 Localizations and Other ASO Techniques That Can Help Your App Expand Globally

Your app already has more than 50,000 downloads. Sooner or later, the domestic market starts to feel limiting. Expansion seems like the natural next step. But choosing the easiest path forward can easily become a strategic mistake.

Some product teams stop at translating descriptions and adding extra screenshots. Such efforts may not bring the expected results. Successful global expansion requires using App Store algorithm mechanisms that most developers either ignore or simply do not know about.

Language Tricks in ASO – 10 Localizations and Misspellings

One of these “tricks” is based on the way Apple indexes keywords. Each country in the App Store has a primary language and additional secondary locales that are also indexed by the algorithm. For example, in the Polish market, Apple indexes not only metadata from the Polish localization, but also metadata from the English (UK) localization. If you use one set of keywords in the Polish section and a different set in the English section, your app in Poland will rank for both groups of keywords.

Most developers think that if they are targeting the Polish market, they only need to fill in Polish metadata. In reality, by using additional localizations, you can gain extra keyword space that will also work in Poland – or in any other market your app is targeting. This means that instead of having 100 characters available for keywords, you can effectively have 200, 300, or even more.

The exact number of available localizations depends on the country. Some languages are indexed globally or across large groups of countries. English (UK) and English (US) are the strongest examples. In most European countries, Apple indexes both the local language and English (UK). However, there are exceptions.

For example, in Switzerland, German, French, Italian and English (UK) are all indexed. The US market offers the greatest opportunities in this area. The App Store in the United States indexes keywords from the primary language (English US) and as many as nine additional localizations. By filling in the keyword field for each of them, you can gain around 1,000 characters of keyword space instead of the standard 100.

At Steady Digital, we use this mechanism to test new keywords or include variations with common spelling mistakes (for example, “forcast” instead of “forecast”), without affecting the professional image of the brand in visible elements such as the title or subtitle. Since keyword fields are invisible to users, they provide a safe place for testing. A misspelled phrase can sometimes be just as popular as the correct one, and including it in a secondary localization makes it possible to capture additional traffic with relatively little effort.

How to Get Low-Cost Traffic from Emerging Markets

Another way to increase App Store visibility is by expanding into alternative markets. Mature apps often focus exclusively on Tier-1 markets such as the United States, the United Kingdom and Canada, where competition and user acquisition costs are the highest. However, data from 2025–2026 shows significant growth and monetization potential in markets outside Europe and North America. Countries such as Brazil and Thailand are currently among the fastest-growing mobile ecosystems in the world.

To scale successfully in these markets, translation alone is not enough. The product must be carefully adapted to local demand. The method we use at Steady Digital is based on monitoring keyword trends in specific regions using specialized tools such as AppTweak. When a keyword suddenly gains momentum in a particular country – for example, when its Search Score jumps from 18 to 40 within a few days – it may indicate a seasonal trend, growing interest, or a major event affecting user behaviour.

This is the moment worth taking advantage of. A quick update of local metadata that includes trending keywords can help an app become a leader in a new niche before competitors even notice the opportunity.

Why Screenshots Matter in ASO

Keywords are not everything. Expanding globally also requires a strong visual strategy. There is a lot to learn from market leaders. Looking at the update history of successful apps such as Cal AI, it becomes clear that continuous testing and optimisation of screenshots plays an important role. In the case of Cal AI, changing the meals shown in screenshots – from pancakes to high-protein salads – is an example of adapting visuals to a specific audience segment, which may vary from country to country.

At Steady Digital, we do not focus only on monitoring rankings. We also use the Worldwide Check feature, which allows us to analyse how an app and its biggest competitors perform across multiple countries at the same time. This helps us identify market gaps much faster. For example, if a competitor dominates the US market but pays little attention to Spanish-speaking or German-speaking markets, this creates an ideal opportunity for an established app to expand and gain market share.

App Store Connect allows developers to upload separate screenshots for each language and market localization through localized asset optimization. If you do not upload dedicated screenshots for a specific market, Apple displays the default set – usually the one assigned to the English (US) localization. This makes it possible to show completely different screenshots to users in Germany, Spain or Brazil. In practice, most apps do not take advantage of this feature, which is exactly why it can provide a valuable competitive advantage.

Depending on the market, it is worth adapting:

• the overall design and composition,
• the language used in screenshot overlays,
• featured functions and use cases,
• cultural elements such as food, people and lifestyle references.

These changes can improve conversion rates https://steadydigital.pl/en/digital-sales-enablement-classic-and-interactive-tools-that-accelerate-conversion/ without requiring any modifications to the app itself.

Why Localization Will Be a Priority in 2025–2026

Forecasts for 2026 are clear: localization will remain one of the most important growth drivers for mobile apps. For apps with more than 50,000 downloads, expanding beyond the domestic market – and beyond familiar growth patterns – is one of the simplest ways to increase revenue.

Steady Digital helps companies go through this process by making full use of the localization opportunities available in App Store Connect to increase app downloads. Instead of repeating the same keywords across different markets, we create a network of unique keyword sets distributed across multiple regions, making your brand visible to millions of new users worldwide.

We also help with competitor analysis, market gap identification and visual optimization, ensuring that your App Store presence is tailored to local cultural contexts and user expectations.
