App Store Metadata

Manage App Store metadata and optimize for ASO using EAS Metadata.

What is EAS Metadata?

EAS Metadata automates App Store presence management from the command line using a store.config.json file instead of manually filling forms in App Store Connect. It includes built-in validation to catch common rejection pitfalls.

Current Status: Preview, Apple App Store only.

Getting Started

Pull Existing Metadata

If your app is already published, pull current metadata:

eas metadata:pull

This creates store.config.json with your current App Store configuration.

Push Metadata Updates

After editing your config, push changes:

eas metadata:push

Important: You must submit a binary via eas submit before pushing metadata for new apps.

Configuration File

Create store.config.json at your project root:

{
  "configVersion": 0,
  "apple": {
    "copyright": "2025 Your Company",
    "categories": ["UTILITIES", "PRODUCTIVITY"],
    "info": {
      "en-US": {
        "title": "App Name",
        "subtitle": "Your compelling tagline",
        "description": "Full app description...",
        "keywords": ["keyword1", "keyword2", "keyword3"],
        "releaseNotes": "What's new in this version...",
        "promoText": "Limited time offer!",
        "privacyPolicyUrl": "https://example.com/privacy",
        "supportUrl": "https://example.com/support",
        "marketingUrl": "https://example.com"
      }
    },
    "advisory": {

  }
}

App Store Optimization (ASO)

Title Optimization (30 characters max)

The title is the most important ranking factor. Include your brand name and 1-2 strongest keywords.

{
  "title": "Budgetly - Money Tracker"
}

Best Practices:

• Brand name first for recognition
• Include highest-volume keyword
• Avoid generic words like "app" or "the"
• Title keywords boost rankings by ~10%

Subtitle Optimization (30 characters max)

The subtitle appears below your title in search results. Use it for your unique value proposition.

{
  "subtitle": "Smart Expense & Budget Planner"
}

Best Practices:

• Don't duplicate keywords from title (Apple counts each word once)
• Highlight your main differentiator
• Include secondary high-value keywords
• Focus on benefits, not features

Keywords Field (100 characters max)

Hidden from users but crucial for discoverability. Use comma-separated keywords without spaces after commas.

{
  "keywords": [
    "finance,budget,expense,money,tracker,savings,bills,income,spending,wallet,personal,weekly,monthly"
  ]
}

Best Practices:

• Use all 100 characters
• Separate with commas only (no spaces)
• No duplicates from title/subtitle
• Include singular forms (Apple handles plurals)
• Add synonyms and alternate spellings
• Include competitor brand names (carefully)
• Use digits instead of spelled numbers ("5" not "five")
• Skip articles and prepositions

Description Optimization

The iOS description is NOT indexed for search but critical for conversion. Focus on convincing users to download.

{
  "description": "Take control of your finances with Budgetly, the intuitive money management app trusted by over 1 million users.\n\nKEY FEATURES:\n• Smart budget tracking - Set limits and watch your progress\n• Expense categorization - Know exactly where your money goes\n• Bill reminders - Never miss a payment\n• Beautiful charts - Visualize your financial health\n• Bank sync - Connect 10,000+ institutions\n• Cloud backup - Your data, always safe\n\nWHY BUDGETLY?\nUnlike complex spreadsheets or basic calculators, Budgetly learns your spending habits and provides personalized insights.

}

Best Practices:

• Front-load the first 3 lines (visible before "more")
• Use bullet points for features
• Include social proof (user counts, ratings, awards)
• Add a clear call-to-action
• Mention privacy/security for sensitive apps
• Update with each release

Release Notes

Shown to existing users deciding whether to update.

{
  "releaseNotes": "Version 2.5 brings exciting improvements:\n\n• NEW: Dark mode support\n• NEW: Widget for home screen\n• IMPROVED: 50% faster sync\n• FIXED: Notification timing issues\n\nLove Budgetly? Please leave a review!"
}

Promo Text (170 characters max)

Appears above description; can be updated without new binary. Great for time-sensitive promotions.

{
  "promoText": "🎉 New Year Special: Premium features free for 30 days! Start 2025 with better finances."
}

Categories

Primary category is most important for browsing and rankings.

{
  "categories": ["FINANCE", "PRODUCTIVITY"]
}

Localization

Localize metadata for each target market. Keywords should be researched per locale—direct translations often miss regional search terms.

{
  "info": {
    "en-US": {
      "title": "Budgetly - Money Tracker",
      "subtitle": "Smart Expense Planner",
      "keywords": ["budget,finance,money,expense,tracker"]
    },
    "es-ES": {
      "title": "Budgetly - Control de Gastos",
      "subtitle": "Planificador de Presupuesto",
      "keywords": ["presupuesto,finanzas,dinero,gastos,ahorro"]
    },
    "ja": {
      "title": "Budgetly - 家計簿アプリ",
      "subtitle": "簡単支出管理",
      "keywords": ["家計簿,支出,予算,節約,お金"]
    },
    "de-DE": {
      "title": "Budgetly - Haushaltsbuch",
      "subtitle": "Ausgaben Verwalten",
      "keywords": ["budget,finanzen,geld,ausgaben,sparen"]
    }
  }
}

Supported Locales: ar-SA, ca, cs, da, de-DE, el, en-AU, en-CA, en-GB, en-US, es-ES, es-MX, fi, fr-CA, fr-FR, he, hi, hr, hu, id, it, ja, ko, ms, nl-NL, no, pl, pt-BR, pt-PT, ro, ru, sk, sv, th, tr, uk, vi, zh-Hans, zh-Hant

Dynamic Configuration

Use JavaScript for dynamic values like copyright year or fetched translations.

Basic Dynamic Config

// store.config.js
const baseConfig = require("./store.config.json");

const year = new Date().getFullYear();

module.exports = {
  ...baseConfig,
  apple: {
    ...baseConfig.apple,
    copyright: `${year} Your Company, Inc.`,
  },
};

Async Configuration (External Localization)

// store.config.js
module.exports = async () => {
  const baseConfig = require("./store.config.json");

  // Fetch translations from CMS/localization service
  const translations = await fetch(
    "https://api.example.com/app-store-copy"
  ).then((r) => r.json());

  return {
    ...baseConfig,
    apple: {
      ...baseConfig.apple,
      info: translations,
    },
  };
};

Environment-Based Config

// store.config.js
const baseConfig = require("./store.config.json");

const isProduction = process.env.EAS_BUILD_PROFILE === "production";

module.exports = {
  ...baseConfig,
  apple: {
    ...baseConfig.apple,
    info: {
      "en-US": {
        ...baseConfig.apple.info["en-US"],
        promoText: isProduction
          ? "Download now and get started!"
          : "[BETA] Help us test new features!",
      },
    },
  },
};

Update eas.json to use JS config:

{
  "cli": {
    "metadataPath": "./store.config.js"
  }
}

Keyword Research Tips

1. Brainstorm features - List all app capabilities
2. Mine reviews - Find words users actually use
3. Analyze competitors - Check their titles/subtitles
4. Use long-tail keywords - Less competition, higher intent
5. Consider misspellings - Common typos can drive traffic
6. Track seasonality - Some keywords peak at certain times

Metrics to Monitor

• Impressions - How often your app appears in search
• Product Page Views - Users who tap to learn more
• Conversion Rate - Views → Downloads
• Keyword Rankings - Position for target keywords
• Category Ranking - Position in your categories

VS Code Integration

Install the Expo Tools extension for:

• Auto-complete for all schema properties
• Inline validation and warnings
• Quick fixes for common issues

Common Issues

"Binary not found"

Push a binary with eas submit before pushing metadata.

"Invalid keywords"

• Check total length is ≤100 characters
• Remove spaces after commas
• Remove duplicate words

"Description too long"

Description maximum is 4000 characters.

Pull doesn't update JS config

eas metadata:pull creates a JSON file; import it into your JS config.

CI/CD Integration

Automate metadata updates in your deployment pipeline:

# .eas/workflows/release.yml
jobs:
  submit-and-metadata:
    steps:
      - name: Submit to App Store
        run: eas submit -p ios --latest

      - name: Push Metadata
        run: eas metadata:push

Tips

• Update metadata every 4-6 weeks for optimal ASO
• 70% of App Store visitors use search to find apps
• Apps with 4+ star ratings get featured more often
• Localized apps see 128% more downloads per country
• First 3 lines of description are most critical (shown before "more")
• Use all 100 keyword characters—every character counts
