What Is ASO (App Store Optimization) and Why It Matters
Basics4 minInnovialabs editorial team
In short
ASO (App Store Optimization) is the work on your app's store page in the App Store and Google Play so it gets found in search more often and installed more often. You control the title, keywords, description, visuals and reviews, while the store also weighs installs and user behavior.
What ASO is
ASO (App Store Optimization) is optimizing your app's page in the stores. It has two goals:
- Visibility — so the app ranks higher in search and collections for the right queries.
- Conversion — so a person who opens the page taps "Install".
For many apps, store search is one of the main sources of installs. Without ASO even a good product gets lost among competitors, and ads cost more because a weak page converts paid traffic poorly.
How search and ranking work
Store algorithms are closed, but the general logic is known. Ranking depends on two groups of factors:
- Relevance. How well the page text — title, subtitle, keywords, description — matches the query.
- Quality and popularity. Install volume and momentum, rating and reviews, retention, uninstalls, stability and crash rate.
The store wants to show an app that people will install and keep. That is why page conversion and product quality affect rankings as much as text does.
What you control
| Element | App Store | Google Play |
|---|---|---|
| Title | Up to 30 characters, indexed | Up to 30 characters, indexed |
| Subtitle / short description | Subtitle up to 30 characters | Short description up to 80 characters |
| Keywords | Hidden field up to 100 characters | No separate field |
| Full description | Barely affects search | Indexed, up to 4000 characters |
| Visuals | Icon, screenshots, preview video | Icon, screenshots, video, feature graphic |
Hence different approaches: on the App Store you spread keywords across the title, subtitle and hidden field; on Google Play you use key phrases naturally in the description.
Practical steps
- Research keywords. What words do people use to look for a solution to your problem? Check store search suggestions, competitor titles and user reviews.
- Write the title. Brand plus the main keyword: "Name — grocery delivery". Do not turn it into a list of words.
- Fill fields without repeats. On the App Store, a word already in the title does not need repeating in the keyword field. Separate words with commas and no spaces.
- Make screenshots sell. The first two or three screenshots are visible in search results. Each should show one benefit in large text, not just a bare interface screen.
- Work on reviews. Ask for a rating at a moment of user success, not at launch, and reply to negative reviews.
- Localize. Separate texts and screenshots for every language and market: for Uzbekistan, for example, in Uzbek and Russian.
- Test. The App Store offers product page optimization tests, Google Play offers store listing experiments. Change one thing at a time.
How ASO differs from web SEO
| Web SEO | ASO | |
|---|---|---|
| Where people search | Search engines | Search inside the store |
| Text volume | Unlimited | Strict character limits |
| Backlinks | An important factor | Practically irrelevant |
| Behavior signals | Clicks, time on site | Installs, retention, uninstalls |
| Goal | A visit to the site | An app install |
| Speed of changes | Site edits go live instantly | On the App Store, metadata updates ship with a new version |
What they share: both revolve around what people search for, and both need ongoing work rather than a one-time setup.
Common mistakes
- Stuffing the title with keywords — it hurts readability and can break store rules.
- Using competitor names in keywords.
- Screenshots of bare screens with no explanation.
- Ignoring reviews and rating: a low score hurts both ranking and conversion.
- Doing ASO once and forgetting it: queries, competitors and algorithms change.
