App Store SEO
App store SEO, usually called app store optimization (ASO), is the practice of improving a mobile app's visibility and conversion rate in app store search results and browse surfaces.
Key takeaways
- ASO is distinct from web SEO: focus on app store algorithms, metadata, and creatives.
- Keyword research is the foundation – prioritize relevance, volume, and rankability.
- Visual assets (icon, screenshots) are conversion drivers, not just decoration.
- Ratings and reviews directly influence both ranking and conversion.
- Localization is a standard practice, not an afterthought.
For SEO practitioners, ASO drives organic app installs by improving how often an app appears for relevant queries and how effectively its listing converts views into downloads.
Example: Optimizing a fitness app for 'workout tracker'
- App name: 'FitTrack – Workout Tracker & Gym Log' (includes primary keyword).
- Subtitle: 'Log exercises, track progress, get fit' (secondary keywords).
- Keyword field: 'exercise log, gym tracker, fitness planner, weight training'.
- Screenshots: Show app in use with clear call-to-action overlays (e.g., 'Start your first workout').
- Result: After 3 weeks, app ranks #5 for 'workout tracker' and installs increase 40%.
Quick-start: 5 steps to launch ASO
- Research keywords – Use tools like App Annie or Sensor Tower to find high-volume, relevant terms.
- Optimize metadata – Place primary keyword in app title, secondary in subtitle/short description, and fill keyword field (iOS) or description (Android) with related terms.
- Design high-converting creatives – Create an icon that stands out, and screenshots that highlight key features with text overlays.
- Encourage ratings and reviews – Prompt users after a positive experience; respond to reviews to build trust.
- Localize for target markets – Translate metadata and creatives for each country, adapting keywords to local language and search behavior.
How to judge ASO success
- Keyword ranking: Track position for target terms in both stores.
- Conversion rate (CVR): Percentage of listing views that result in installs.
- Organic install volume: Number of installs from search and browse.
- Rating and review trends: Average rating and number of reviews over time.
- Competitor benchmarking: Compare your app's performance to top competitors for same keywords.
Common mistakes in ASO
- Keyword stuffing titles or descriptions – hurts relevance and conversion.
- Treating ASO like web SEO – ignoring character limits, field rules, and store-specific indexing.
- Neglecting visual assets – poor screenshots or icon reduce CVR even with high ranking.
- Skipping localization – missing out on non-English markets with different keyword intent.
- Ignoring ratings and reviews – negative reviews or lack of social proof lower trust and installs.
