Impressions are free. Installs aren't.
App Store Optimization (ASO) Services & Agency
App Store Optimization is the app store's SEO and CRO combined — the work that turns store impressions into installs without paying for the impression. This is how ASO actually works, so you can tell a real operator from a keyword-stuffer. No pitch. Just the model.
What’s inside
ASO isn’t a checklist. It’s the store’s SEO and CRO.
The app store is a search engine with a checkout attached. Half of ASO is discoverability — the keywords, category, and ratings that decide who sees you. The other half is conversion — the icon, screenshots, title, and preview video that decide who installs. Run them as one loop and every impression works harder, paid and organic alike.
- Two engines, one page. Discoverability earns the impression; conversion earns the install. Neither wins alone.
- The store listing is the whole funnel. There is no landing page after it — the product page is the landing page.
- A point of conversion compounds. Lift the install rate and every future impression — bought or earned — converts a little better, forever.
On the average, five times as many people read the headline as read the body copy.

ASO sits inside the wider growth program: it feeds and is fed by performance marketing user-acquisition and conversion rate optimization. The store listing is where paid and organic demand both land.
First they have to find you.
Before conversion can matter, the store has to show your listing. Discoverability is the store's ranking algorithm — a different lever set from your creative. Tap each lever to see what it does and how much it tends to move rank.
Here is the trap most teams fall into: they treat discoverability as a one-time metadata dump, then wonder why rank never moves. The store algorithm rewards relevance and momentum, not word count. A title that names a real, searched job beats one crammed with synonyms; a category that matches how buyers browse beats the one that flatters your roadmap. And because ratings feed both engines at once, the fastest discoverability win is often a better product experience — not another keyword. Think of it the way a good SEO thinks about a web page: earn the ranking, do not trick the index into it.
Discoverability is the app store's version of SEO. The same instincts apply: match real search demand, earn authority (here, ratings), and never keyword-stuff a field the algorithm already discounts. See the ASO glossary entry.
A few points of CVR, across every impression.
Here is why conversion is the highest-leverage half of ASO. A lift to your install rate applies to every impression you will ever get — the free organic ones and the paid ones you already bought. Move the slider and watch the extra installs, and the lower effective cost per install, appear.
Illustrative: 500,000 monthly impressions, a 3.0% product-page CVR, 40% of impressions from paid at a $2.50 CPI. A CVR lift stretches the same ad budget over more installs (effective CPI falls by the lift), and lifts the free organic installs by the same rate. RGM analysis · illustrative.
This is the same math behind conversion lift and cost-per-install. The store listing is the one lever that improves paid and organic economics at the same time.
Ratings are the proof shown at the moment of choice.
Your star rating sits right beside the GET button and feeds the ranking algorithm at the same time. Higher ratings lift conversion; higher conversion and volume lift rank; better rank brings more installs — and more reviews. Pick a rating to see the flywheel turn.
The uncomfortable truth is that a rating is a lagging indicator of the product and a leading indicator of growth. You cannot buy your way past a two-star app; a slick listing on a broken experience just helps more people find out it is broken. The durable move is to close the loop between reviews and the roadmap — read what one-star reviews keep saying, fix the top three, and the stars follow. Then ask for the review at the moment the user just succeeded at something, never at launch or mid-task.
Never fake reviews — it violates store guidelines2 and the flywheel only compounds if the product earns the stars. Prompt at moments of delight, and route unhappy users to support before the store. Rating-to-conversion figures here are illustrative. RGM analysis.
Three reads that check each other.
No single number tells you if ASO is working. The store scoreboard is conversion rate — installs divided by impressions. Discoverability shows up as keyword rank and impression share. Creative is judged by a real experiment, not a hunch. Switch the read to see each one.
The most common measurement mistake in ASO is confusing motion with progress. You ship a new icon, installs tick up the same week, and everyone claims the win — but a seasonal spike, a press hit, or a paid push could have done it. That is why creative gets judged by a controlled store experiment, not a before-and-after chart. Rank and impression share tell you whether the discoverability engine is turning; conversion rate tells you whether the listing is earning the install; the experiment tells you which change actually caused the move. Read all three, or you are guessing.
The App Store defines conversion rate as downloads ÷ impressions in App Analytics4; Google Play Console reports store listing conversion the same way5. We wire both to analytics so ranking noise never gets mistaken for a real move. Figures illustrative.
The RGM ASO loop.
ASO is never done — the store, your competitors, and search demand all move. So we run it as a loop: research, optimize, test, measure, and repeat. Every cycle raises the floor for the next.
The loop pairs with user-acquisition (paid installs feed the experiments) and CRO (the same testing rigor, one screen earlier). One owner, one scoreboard.

- What is App Store Optimization (ASO)?
- ASO is the practice of improving an app’s visibility and conversion on the App Store and Google Play. It combines the store’s SEO (keywords, category, ratings) with its CRO (icon, screenshots, title, preview video), turning store impressions into installs.
- What are the two halves of ASO?
- Discoverability — the keywords, category, and ratings that decide who sees the listing — and conversion — the icon, screenshots, title, subtitle, and preview video that decide who installs. The store listing is the landing page.
- Why does conversion rate matter so much in ASO?
- A lift to the product-page conversion rate applies to every impression, paid and organic, so a few points of CVR compound across all future traffic and lower the effective cost per install.
- How is ASO measured?
- By impression-to-install conversion rate (the store scoreboard), keyword rank and impression share (discoverability), and paid CVR from custom product pages or store listing experiments (creative), which prove cause rather than assume it.
- How do you choose the best ASO agency?
- Look for real store experiments (custom product pages or store listing experiments), conversion read as installs divided by impressions, ratings strategy that earns rather than fakes stars, and discoverability separated from noise.
