How to Find App Store Localization Gaps in 2026

War Diary // Field Report 01 // ASO Intelligence Unit

Day 47. The front line shifted again.

Apple just pushed another 12 locales into production. Your competitor updated their metadata in 43 languages overnight. Your app? Still running English-only subtitles in markets that represent 68% of global downloads. You are bleeding installs and you don't even know where the wounds are.

This is a war of visibility. The App Store is a 1.9 million-app battlefield, and localization is the reconnaissance drone most developers forgot to deploy. By the time you notice your Portuguese CVR has flatlined, a competitor from Sao Paulo has already captured your chart position for good.

Welcome to the war diary. Here is how you find the gaps before they find you.

H2: The Localization Intelligence Gap 🎯

Let me be blunt. Most ASO teams operate blind when it comes to localization coverage. They know their primary market. They maybe know their top three. Beyond that? Darkness.

The intelligence gap looks like this:

• You localize your app's store listing into 8 languages. Feels adequate.
• Your top competitor localized into 34. Feels excessive.
• Between those two numbers lives a stretch of territory called "the gap": every locale where your competitor ranks and you do not even show up.
• That gap is not theoretical. It is measurable. It is crawable. And right now, someone else is mining it.

Key Takeaway: The localization gap is not an abstract concept. It is the delta between the locales you cover and the locales your competitors cover. That delta equals lost impressions equaling lost installs equaling lost revenue.

In 2026, Apple supports over 40 App Store locales. Each one represents a separate indexing surface, a separate keyword ecosystem, a separate conversion funnel. When you skip a locale, you are not just skipping a language. You are abandoning an entire discoverability channel.

Why does this happen? Three reasons dominate the field:

1. Lazy default thinking. "Our app is in English, and everyone speaks English." No. They browse in their native language. They search in their native language. They download in their native language.

2. No systematic visibility. Teams cannot fix gaps they cannot see. Without a tool to crawl competitor listings across all locales simultaneously, you are guessing.

3. Resource paralysis. "We can't translate into 40 languages." You do not need 40 perfect translations. You need to identify the 8 to 12 locales that your competitive set cares about most, then close those gaps first.

H2: Scouting the Terrain: How to Audit Your Localization Footprint 🔭

Before you can close gaps, you must map them. This requires a structured audit of both your own listings and your competitors' listings across every available locale.

H3: Step 1: Catalog Your Own Coverage 📋

Pull up App Store Connect. Go to your app's localization section. Count the languages. Write them down. Now open the listing in each locale and verify:

• Title is localized (not just copy-pasted English)
• Subtitle is localized
• Keyword field is filled with locale-relevant keywords (not English leftovers)
• Screenshots have localized text overlays
• Description (if used) reads naturally

You will likely find half-translated locales. Places where you added the language but left the keyword field in English. These are false positives: they look like coverage in your dashboard but deliver zero indexing value in that market.

H3: Step 2: Map Competitor Coverage 🔍

This is where the work used to take weeks. Now it takes minutes.

You cannot manually visit 40+ locale variants of 10 competitor apps. That is 400+ page loads, each requiring locale spoofing and careful note-taking. Instead, you automate the reconnaissance using the Apple App Store Localization Scraper on Apify. This actor crawls any app ID across all available App Store locales and returns structured data: localized titles, subtitles, keyword fields, descriptions, and screenshot URLs per locale.

Key Takeaway: Manual locale-by-locale auditing does not scale. Automated scraping turns a 40-hour manual audit into a 15-minute data pull.

Run the scraper on your own app ID first. Then run it on your top five competitors. Export the results. Now you have a localization coverage matrix that shows exactly which locales each competitor targets and which ones they skip.

H2: Identifying the Gaps: A Data-Driven Approach 📊

Now comes the analysis. Lay your competitor data side by side with your own. The pattern will emerge fast.

H3: The Locale Heat Map 🗺️

Build a simple matrix. Rows are locales. Columns are competitors. Cells contain a binary value: localized (1) or not (0). Then add your own app as the first column.

The locales where competitors show 1 and you show 0? Those are your gaps. Prioritize them by two factors: the number of competitors present (higher = more competitive locale worth entering) and the market's download volume (use Apple's market data or third-party estimates).

H3: Keyword Opportunity Mapping 🔑

Gaps are not just about presence. They are about keyword targeting. A competitor may be present in pt-BR but ranking for different keywords than you would target. Use the Apple App Store Localization Scraper to extract the keyword field from each competitor's localized listing. Compare their keyword strategy per locale against what you would realistically target.

Look for:

• Keyword clusters competitors dominate that you ignore entirely. Example: a fitness app seeing competitors rank for "treino em casa" (home workout in Portuguese) while you have no Portuguese listing at all.
• Low-competition keyword opportunities. Locales where competitors have thin keyword coverage, suggesting an underserved search landscape.
• Semantic mismatches. Direct translation misses. The English keyword "budget tracker" becomes "gerenciador de financas" in Portuguese, not the literal "rastreador de orcamento." If your competitor got this wrong, that is your opening.

Key Takeaway: A localization gap is not just a missing language. It is a missing keyword universe. Every untranslated locale represents hundreds of search terms where you have zero presence.

H2: The Technical Proof: Scraping Your Way to Clarity 🔬

Enough theory. Let me show you the operational playbook.

Technical Proof Block

TARGET APP ID: 1234567890
LOCALES SCANNED: 42
SCRAPER: Apple App Store Localization Scraper (Apify)
RUN TIME: ~4 minutes per app
OUTPUT FORMAT: JSON (flat), CSV export available

--- SAMPLE OUTPUT (abbreviated) ---

Locale: pt-BR
  title: "Financas Pessoais - Orcamento"
  subtitle: "Controle seu dinheiro"
  keywords: "financas,orcamento,despesas,renda,poupanca"
  screenshots_localized: true (6 of 6)

Locale: ko
  title: "Personal Finance - Budget Tracker"
  subtitle: "Track your money"  
  keywords: "budget,tracker,finance,money,expense"
  screenshots_localized: false (0 of 6, English screenshots reused)

--- GAP ANALYSIS ---

My App Coverage: 8 locales
Comp A Coverage: 22 locales
Comp B Coverage: 19 locales
Comp C Coverage: 31 locales

GAPS IDENTIFIED (My App = 0, >=2 Competitors = 1):
  - pt-BR  (3 competitors present)  --> PRIORITY: HIGH
  - ko     (2 competitors present)  --> PRIORITY: HIGH
  - ar-SA  (2 competitors present)  --> PRIORITY: MEDIUM
  - th     (1 competitor present)   --> PRIORITY: LOW
  - vi     (2 competitors present)  --> PRIORITY: MEDIUM
  - tr     (3 competitors present)  --> PRIORITY: HIGH

ESTIMATED IMPACT OF CLOSING HIGH-PRIORITY GAPS:
  pt-BR: +14% addressable downloads (Brazil top-10 market)
  ko: +8% addressable downloads (South Korea top-15 market)
  tr: +6% addressable downloads (Turkey top-20 market)

The data speaks. The Apify localization scraper pulls this in a single run. No manual browsing. No locale-switching in Xcode. No guessing. You get structured data that tells you exactly where your competitors deploy localized assets and where they leave the field open for you.

H2: Gap-Closing Strategy: From Data to Action ⚔️

Finding the gaps is recon. Closing them is combat. Here is the operational sequence:

H3: Phase 1: Quick Wins (Week 1) ⚡

Target the high-priority gaps you identified. These are locales where:

• At least two competitors are already localized
• The market represents meaningful download volume (top 25 countries minimum)
• You already have some localization infrastructure (e.g., you translated the app but not the store listing)

For each target locale:

1. Localize title and subtitle first. These carry the heaviest indexing weight.
2. Build a locale-specific keyword field. Do not translate your English keywords. Research local search behavior using App Store search suggestions in that locale.
3. Upload at least 3 localized screenshots with native-language overlays.

You do not need perfect native-copywriting-grade translations for phase one. You need good enough. Get the listing indexed. Get it serving impressions. Refine later.

H3: Phase 2: Keyword Deepening (Weeks 2-3) 📈

Now that you have basic presence in gap locales, deepen your keyword coverage. Re-run your localization scraper on your own newly localized listings. Verify that your keyword fields are actually locale-appropriate. Check that titles and subtitles are not truncating. Confirm screenshots rendered correctly.

Then iterate on keyword selection per locale. Track ranking changes. If you invested in pt-BR, are you now appearing in search results for "gerenciador de financas"? If not, adjust the keyword field and re-test.

H3: Phase 3: Full Coverage Push (Month 2-3) 🏁

With quick wins validated and keyword coverage deepened in priority locales, expand to medium-priority gaps. Apply the same workflow. By month three, you should have closed all gaps where competitors hold presence and you previously had none.

Key Takeaway: Closing localization gaps is not a one-time project. It is an ongoing operational rhythm. Competitors add locales. Apple adds new supported languages. The gap shifts. Your recon must shift with it.

H2: Maintaining Surveillance: Continuous Gap Monitoring 📡

The battlefield does not hold still. Every month, competitors update their localization strategy. New apps enter your category with aggressive multi-locale launches. Apple periodically adds new locale options (the last three years saw Thai, Vietnamese, and Hindi additions, among others).

You need ongoing surveillance, not a single audit.

H3: Setting Up Recurring Scans 🔄

Schedule the Apple App Store Localization Scraper on Apify to run weekly or biweekly on your core competitor set. Set up Apify schedules to automate this. Each run produces a fresh localization coverage snapshot. Compare against your previous snapshot. Flag any new locales that competitors added since last scan.

Build a simple dashboard. Track locale count per competitor over time. When a competitor jumps from 12 locales to 18, you want to know which 6 they added, and you want to know within the same week.

H3: Alert Logic 🚨

Configure your monitoring to alert on:

• New competitor locale additions. A competitor entering a locale you do not cover is a threat event.
• Competitor locale removals. If a competitor drops a locale, that may signal low ROI. Validate before you follow.
• Keyword field changes per locale. Competitors updating keywords in pt-BR means they are optimizing. You should respond.

Key Takeaway: Localization is a dynamic theater. Static audits age out in weeks. Continuous automated monitoring keeps your intelligence current and your response time short.

H2: Common Recon Mistakes to Avoid ⚠️

Before you deploy, learn from the failures I have witnessed in the field:

Mistake 1: Translating keywords instead of localizing them. Direct translation of your English keyword list into Portuguese using Google Translate will produce keywords that real users do not search for. Use local search suggestion data, local competitor keyword analysis, and native speaker input. The Apify scraper gives you the competitor keyword data. The interpretation must come from someone who understands the market.

Mistake 2: Ignoring screenshot localization. Apple ranks localized apps higher in local markets. Screenshots are part of the listing. English screenshots in a Portuguese listing tell the user (and algorithm) that you did not really commit to this market.

Mistake 3: Treating all locales as equal priority. Adding Thai before Portuguese when Brazil is a top-5 download market and Thailand is top-30 means you are optimizing for effort rather than impact. Follow the data. Close high-impact gaps first.

Mistake 4: Set and forget. You localized into 15 languages in 2024. You have not touched those listings since. Meanwhile, your competitors have updated keywords four times. Your Portuguese listing still references a feature you deprecated six months ago. Localization requires maintenance. Schedule quarterly reviews.

Mistake 5: Copying competitor keywords verbatim. Your competitors are not perfect. Some of their localized keywords are poorly chosen. Use their data as a starting point, not an endpoint. Differentiate where you can.

FAQ: Field-Tested Answers 🪖

Q: How many App Store locales should a mid-market app target at minimum in 2026?
A: It depends on your category and geographic footprint, but the baseline is shifting. Two years ago, 8 to 12 locales was strong. Now, your serious competitors are running 20+. Minimum viable coverage in 2026 should include every locale where you have organic downloads above 500 per month and every locale where at least two direct competitors are present. For most mid-market apps, that lands somewhere between 15 and 25 locales.

Q: Can I localize my App Store listing without localizing the app itself?
A: Yes, and you should. The App Store listing (title, subtitle, keywords, screenshots, description) is indexed separately from the in-app experience. A Portuguese-language listing will surface in Portuguese App Store search even if the app UI is in English. Conversion may be lower than a fully localized app, but the impression and click coverage you gain far outweighs the conversion penalty. Get the listing localized first, then localize the app experience as resources allow.

Q: How do I know which locales my competitors are targeting without manually checking each one?
A: Use the Apple App Store Localization Scraper on Apify. Feed it the app ID of any competitor, and it returns their localized metadata for every App Store locale in a single structured output. Run it across your competitor set, build a coverage matrix, and your gap analysis is complete. Manual checking of 40+ locales per competitor is a time trap that no team should accept in 2026.

Q: Should I prioritize locales by download volume or competitive gap size?
A: Both matter, and they often overlap. Start with a combined score: weight download volume at 60% and competitive gap presence at 40%. A locale like pt-BR (high downloads, high competitor presence for your category) scores well on both. A locale like vi (moderate downloads, low competitor presence) may be a quick win with less resistance. Use the gap matrix to make prioritization a data decision, not a gut decision.

Final Dispatch 🏁

The localization gap is not a theory. It is a measurable, exploitable, closable difference between your App Store surface area and your competitors'. Every untranslated locale is a door you left closed while competitors walk through it daily.

Find the gaps. Close the gaps. Monitor the gaps. Repeat.

The data is waiting. The scraper is ready. The field is yours.
