App Store Optimization (ASO): a practical guide for 2026

App Store Optimization (ASO) is the practice of getting your app found in store search and then convincing people to install it once they find it. Those are two separate jobs: being discoverable handles your traffic, while a persuasive store listing handles your conversion rate. A strong listing wins on both.

Working with developers’ apps over the years, we keep seeing the same pattern: teams pour effort into the product but treat the store listing as an afterthought. As a result a genuinely good app loses a large share of its organic installs simply because people never find it for obvious queries. Here is how to fix that.

The two layers of ASO

• Textual (for the algorithm). Title, subtitle, the keyword field (App Store) and the description. This is how the store decides which searches to show your app for.
• Visual (for the human). Icon, screenshots, preview video, rating and reviews. This drives the install decision, not impressions.

Doing only one is a classic mistake. You can rank for a query and waste the impressions because the icon doesn’t catch the eye — or design beautiful screenshots no one ever sees because the app doesn’t rank.

Step 1. Research your keywords

Your keyword set is the list of queries your audience actually types. Build it from real sources, not guesses:

1. Store search autosuggest — type a seed word and note what the store proposes. Those are live, high-demand queries.
2. Direct competitors — which words sit in their title and subtitle.
3. Your reviews — users describe the app in their own words, which are ready-made query phrasings.
4. ASO tools (AppTweak, Sensor Tower, App Radar) for volume and difficulty estimates.

Then group keywords by volume and relevance. High-volume head terms (“fitness”, “bank”) bring lots of traffic but are brutally competitive — a new app won’t crack them. Mid- and long-tail terms (“home workout log”, “expense tracker by category”) bring fewer impressions but you can actually reach the top and capture a focused, high-converting audience.

Step 2. Place keywords by field

Each field carries different weight. Roughly, in order of importance:

Field	App Store	Google Play / RuStore
Title	up to 30 chars, maximum weight	up to 30 chars, maximum weight
Subtitle / short description	up to 30 chars, high weight	up to 80 chars, high weight
Keyword field	100 chars, hidden from users	—
Long description	barely indexed	indexed, affects ranking

One App Store nuance: don’t repeat words in the keyword field that are already in the title — the algorithm counts a word once. Don’t waste your 100 characters on duplicates, separate words with commas and no spaces, and never include competitor brand names (it can get your listing rejected on review).

Google Play and RuStore work differently

Here the full description is indexed, so weave target queries naturally into the copy — roughly 3–5 mentions of the main keyword per 1,000 characters, without stuffing. Google’s algorithms have long distinguished meaningful text from keyword-stuffed copy, and over-optimization sinks a listing. RuStore largely follows the same logic but with lower competition right now.

Step 3. Work on conversion

You drove the traffic — now convert it. People decide in seconds, and the biggest levers are:

• Icon. Simple, high-contrast, legible at small size. Test it against the grey of a results list, not on a pretty mockup.
• The first two screenshots. They’re seen without scrolling, so they do the selling. Not a “gallery of screens” but a clear benefit: what the user gets.
• Rating and fresh reviews. An app at 4.6 with a hundred reviews beats an empty 5.0 listing, even with identical features. People trust volume of feedback.

Validate every visual hypothesis with an A/B test (Google Play has built-in store listing experiments; the App Store has Product Page Optimization). Changing icons and screenshots “by feel” is a common reason conversion drops after a redesign instead of rising.

Step 4. Measure and repeat

ASO is a loop, not a one-off setup. Every 2–4 weeks, review keyword rankings, install conversion rate and visibility, adjust your copy and creatives, then measure again. Stores change algorithms, competitors launch, seasonal demand shifts — a listing that worked six months ago can underperform today.

FAQ

How long until ASO shows results?

You’ll see ranking shifts within 1–2 weeks of updating the listing. Sustained growth is a 1–3 month horizon, because algorithms need to accumulate behavioural data.

Does ASO replace paid ads?

No — they complement each other. ASO delivers cheap organic traffic over time; ads and motivated installs give a fast push. The best results come when paid traffic nudges rankings while a strong listing converts the people who arrive.

Can I do ASO myself?

The basics, yes — especially with this checklist. But volume research, competitor analysis and continuous testing are easier with tools or a partner, otherwise the work tends to get dropped.
