How do I do App Store Optimization (ASO) for my app?
App Store Optimization (ASO) is the work of getting your app found and installed in Apple's App Store and Google Play. It has two halves: discoverability — the keywords in your name, subtitle, and description that decide what you rank for — and conversion — the icon, screenshots, and ratings that turn a store visit into an install. Get the highest-weighted fields right first (on Apple, the app name, subtitle, and keyword field; on Google Play, the title and descriptions), make your icon and first screenshots earn the tap, then improve one change at a time from the store's own analytics.
What App Store Optimization actually is
App Store Optimization is SEO for the app stores: the work of getting your app to show up when people search Apple's App Store or Google Play, and getting the people who see it to actually install. It splits into two jobs that pull different levers. The first is discoverability — ranking for the terms your users search, driven mostly by the keywords in your app's name, subtitle, and description. The second is conversion — turning a store visit into an install, driven by your icon, screenshots, ratings, and the first lines of the listing.
Most of an app's installs come from store search and browse, not from ads or your website, so the listing is not a formality — it is a channel. And unlike a web page you can rewrite hourly, store fields are throttled by review and indexing, so the play is to get the high-leverage fields right, then improve deliberately from real data rather than guessing. For the one-paragraph version of the concept, see what App Store Optimization is.
The App Store and Google Play optimize differently
The two stores rank and index apps differently, and a listing tuned for one is not automatically tuned for the other. The differences worth knowing before you write a single field:
| Lever | Apple App Store | Google Play |
|---|---|---|
| What gets indexed for keywords | The app name (30 chars), subtitle (30), and a hidden 100-char keyword field | The app title (30 chars), short description (80), and the full long description |
| How you place keywords | In the dedicated keyword field; never repeat a word across fields | Naturally across the title and both descriptions; Google reads the whole listing |
| What drives conversion | Icon, first one or two screenshots, ratings, and an optional preview video | Icon, feature graphic, screenshots, ratings, and the short description |
| How fast a change lands | Tied to app review and periodic re-indexing | Re-indexed more continuously, but still not instant |
How to improve your ASO, in order
You don't do ASO all at once; you do the highest-leverage fields first, then iterate from what the store's own analytics tell you. A practical order for a founder:
- Start from the words your users actually type List the real phrases someone would search to find an app like yours — the problem, the category, close competitors' terms. These are the raw material for your name, subtitle, and keyword field. The method in how to do keyword research for your startup transfers straight to the stores.
- Put your best keywords in the highest-weighted fields On Apple that means the app name, subtitle, and the 100-character keyword field, with no word repeated across them. On Google Play it means the title, the short description, and a naturally written long description. Front-load the terms that matter most.
- Win the visual judgment Your icon and first two screenshots are what most visitors decide on before reading anything. Lead the screenshots with the benefit, not a feature tour, and make the first frame legible at thumbnail size. A tool like app-store-screenshots can scaffold store-sized sets fast.
- Earn ratings and reviews, and reply to them Ratings feed both ranking and conversion: a higher star average lifts you in search and reassures the visitor. Prompt happy users to rate at a moment of value, and reply to reviews so prospects see a responsive team. It is the same work as getting testimonials and reviews, aimed at the store.
- Measure, then change one thing at a time Watch impressions, product-page conversion rate, and keyword rankings in App Store Connect and Google Play Console. Change one field or asset, let it re-index, and compare — ASO is a growth loop, not a one-time setup.
One thing building AgentCeres — the AI Growth Officer at agentceres.com — made concrete: reviews and metadata are ongoing work, not a launch-day task. AgentCeres connects to App Store Connect and Google Play to watch reviews and ratings as they land, draft metadata and reply updates, and surface which keywords and pages convert — with a human approving anything that goes public. ASO rewards teams who keep tending the listing, and most founders simply don't have the time to; that gap is exactly what a managed marketing team fills.
FAQ
- How long does ASO take to work?
- Faster than web SEO, but not instant. Keyword and metadata changes are re-indexed within days to a couple of weeks, and conversion changes like a new icon or screenshots affect your install rate as soon as the new assets go live and enough people see them. Because the stores throttle indexing, resist changing everything at once — you won't know what moved the needle. Ship a focused change, let it settle, and read the store analytics before the next one.
- What's the difference between ASO and app store ads?
- ASO is organic: you earn rankings and installs through your listing, keywords, and ratings, and it compounds without a per-install cost. App store ads, like Apple Search Ads or Google Play promotions, are paid placements that buy visibility immediately but stop the moment you stop paying. They work well together — ads can reveal which keywords convert, and ASO turns that into lasting organic reach — but ASO is the durable half.
- Do ratings and reviews really affect ASO?
- Yes, on both stores. A higher average rating tends to lift your ranking in search and browse, and it lifts conversion even more — most people won't install an app rated below four stars when a higher-rated alternative sits right next to it. Reviews also give you honest product feedback and, when you reply, show prospects a team that listens. Treat ratings as a core ASO lever, not an afterthought.
- Should I optimize for the App Store or Google Play first?
- Optimize the store where your users actually are. If you ship on both, don't copy-paste one listing into the other — their keyword indexing and asset requirements differ, so each needs its own keyword plan and, ideally, its own screenshots. If you only have bandwidth for one, start with whichever store drives more of your installs today and get it genuinely right before you split your attention.
- Can I do ASO myself, or do I need a tool?
- You can start by hand: good keyword choices, a clear icon, benefit-led screenshots, and a habit of reading the store analytics take a small app a long way. Tools help once you want to track keyword rankings over time or manage listings across many locales. For most founders the real constraint isn't tooling — it's consistency, because ASO rewards the ongoing attention a listing rarely gets.
