What is app store optimization (ASO)? A plain guide for 2026.
ASO is SEO for the App Store and Google Play: getting found in store search and turning more page views into installs. Here is how it works, and what has changed now that AI reads your listing too.
What is app store optimization? In one line: it is the work of making an app easier to find in the App Store and Google Play, and more likely to be installed once found. It is the cheapest growth channel most apps never fully use.
What is app store optimization (ASO), exactly?
ASO has two halves. Visibility is ranking for the searches your users make and appearing in browse surfaces. Conversion is persuading the people who see your listing to install. Improving either one raises installs; improving both compounds.
How the stores rank apps
Apple is unusually direct: App Store search results are based on text relevance, meaning matches in your title, subtitle, keywords and primary category, and on user behaviour, including downloads, ratings and reviews. Google Play has no keyword field, so your title, short description and full description carry the terms, and its metadata policy polices keyword stuffing in all three. Quality signals such as Android vitals can also cut visibility.
The levers you control
| Lever | App Store | Google Play |
|---|---|---|
| Name / title | 30 characters | 30 characters |
| Second line | Subtitle, 30 characters | Short description, 80 characters |
| Hidden keywords | Keyword field, 100 bytes | None |
| Long text | Description, 4,000 (not a listed search field) | Full description, 4,000 (carries keywords) |
| Visuals | Icon, up to 10 screenshots, up to 3 previews | Icon, feature graphic, up to 8 screenshots per device type |
| Testing | Product page optimization | Store listing experiments |
How to do app store optimization: the order we work in
- Fix what loses installs: crashes, ratings and reviews.
- Research keywords from how people describe the problem. See keyword myths.
- Rewrite metadata: name, subtitle, keywords or short description.
- Rebuild the first screenshots and test them.
- Localize for your biggest markets.
- Repeat monthly, because rankings and competitors move.
Is app store optimization important?
For most apps, store search is the biggest free source of installs, and ASO improves the conversion of every paid install too. In our own work, the Gyan Studios portfolio passed 700,000 installs with zero ad spend. For timelines, see how long ASO takes.
ASO in 2026 also means being readable by AI: Google Play's Ask Play and assistants like Gemini and ChatGPT summarise listings and websites. See ASO, SEO, GEO and AEO for apps.
