App Store Optimization
App store optimization (ASO) is the process of improving a mobile app’s visibility and conversion rate in app stores like Google Play and the Apple App Store.
- Also called
- ASO
- Best for
- Improving app discoverability and install conversion
- Data it reports
- Impressions, installs, conversion rate, keyword rankings, ratings
Key points
- ASO improves an app's visibility in app store search results and its conversion from impressions to installs.
- Keyword research is foundational for ASO and should focus on relevance, search volume, and competition.
- Visual assets such as screenshots, icons, and preview videos strongly affect conversion rates.
- ASO requires ongoing testing and iteration, not a one-time setup.
- Localization is important because app store listings should be adapted for different languages and markets.
How to use it
- Conduct keyword research to identify relevant terms with good search volume and manageable competition.
- Optimize the app title, subtitle or short description, and full description with those keywords, prioritising readability.
- Design compelling screenshots and preview videos that highlight key features and benefits.
- Encourage positive ratings and reviews by prompting satisfied users and responding to feedback.
- A/B test metadata and creative assets to measure which changes lift conversion rate optimization.
- Monitor performance metrics and iterate based on store behaviour changes and user feedback.
How the tools differ
| Feature | Google Play | Apple App Store |
|---|---|---|
| Metadata fields | Title, short description, full description, keywords field | Title, subtitle, keywords field (100 characters), description |
| Ranking signals | Title, description, user ratings, install velocity, backlinks | Title, keywords, user ratings, installs, in-app purchases |
| Testing tools | Google Play Console A/B testing for store listings | Product Page Optimization (A/B testing) in App Store Connect |
| Review management | Reply to reviews publicly | Reply to reviews publicly |
| Localization | Per-country metadata and creative sets | Per-country metadata and creative sets |
What it is not
- ASO is not a one-time metadata edit; it requires ongoing testing and iteration, much like app store seo, as store algorithms and user behaviour evolve.
- ASO is not just about keywords; visual assets, ratings, reviews, and localization all influence discoverability and conversion.
- ASO is not the same for both stores; Google Play and Apple App Store use different ranking signals and metadata fields, so strategies must be platform-specific.
- ASO is not guaranteed to produce immediate results; it takes time to see ranking changes and conversion improvements.
Common mistakes
- Treating ASO as a one-time metadata edit instead of an ongoing testing and iteration process leads to missed opportunities for improvement.
- Using the same optimization strategy for Apple App Store and Google Play ignores different field structures and ranking factors, reducing effectiveness.
- Overloading metadata with keywords instead of prioritizing relevance and readability harms user experience and can trigger penalties.
- Ignoring screenshots, icons, video, ratings, and reviews while focusing only on keywords limits conversion potential.
- Neglecting mobile seo principles such as page speed and user experience can hurt an app's overall performance, even if ASO is strong.
