Most apps are found through store search — and most apps are invisible in it
A large majority of app discovery still happens through browsing and searching within the stores themselves. Yet most teams treat store listings as a publishing formality rather than a ranking surface: default titles, unoptimised subtitles, generic screenshots and no keyword strategy. Meanwhile paid user acquisition costs keep climbing, making organic install growth the difference between viable and unviable unit economics.
Unoptimised store metadata
Title, subtitle and keyword fields are the strongest ASO ranking inputs and are usually filled with brand copy rather than the terms users actually search. It is the cheapest fix available and the most commonly skipped.
Paid acquisition carrying everything
Install costs rise as you exhaust the cheapest audience segments. Without organic install growth the blended cost per install climbs until unit economics stop working.
Ratings suppressing conversion
Store ranking and install conversion both respond strongly to rating and review velocity. A mediocre rating suppresses both simultaneously, compounding the problem in each direction.
No web presence for the app
A large share of app discovery begins with a web search. Without an indexable web presence and app indexing you are invisible to everyone who starts on Google rather than in a store.
Two stores with different rules, plus the web search that precedes both.
App SEO combines App Store Optimisation — ranking inside Apple’s App Store and Google Play — with web SEO that captures the searches happening before anyone opens a store.
The two stores rank differently and require separate work: Apple uses a dedicated keyword field and weights title and subtitle heavily, while Google Play indexes the full description more like a web page. Treating them identically leaves ranking on the table in both.
- Store keyword research — search volume and difficulty per store, since terminology and competition differ meaningfully between Apple and Google.
- Metadata optimisation — title, subtitle, keyword field and description engineered per store rather than copied across both.
- Creative & conversion — icon, screenshots and preview video tested for install conversion, which affects ranking as well as downloads.
- Rating & review strategy — compliant in-app prompting timed to positive moments, plus structured response handling that lifts rating over time.
- Web app SEO — indexable landing pages, app indexing and deep linking so web searches convert into installs.
Why conversion matters for ranking: both stores factor install conversion rate into ranking. Better screenshots do not just win more installs from the same traffic — they lift your position, which brings more traffic.
How we grow organic installs
Six workstreams covering both stores and the web search that precedes them.
Store keyword research
Separate research per store, since Apple and Google use different models, different terminology patterns and different competitive sets. One keyword list across both leaves ranking unclaimed in each.
Metadata engineering
Title, subtitle and keyword field optimised for Apple; full description optimised for Google Play’s indexing. Written per store rather than duplicated across both.
Creative testing
Icon, screenshots and preview video tested for install conversion. Because conversion feeds ranking, creative work compounds — better assets bring both more installs and more impressions.
Rating & review programme
Compliant in-app prompting timed to moments of demonstrated satisfaction, plus structured response handling. Rating affects ranking and conversion simultaneously.
Web app SEO
Indexable landing pages targeting app-related queries, app indexing and deep linking so the significant share of discovery starting on Google converts into installs.
Iterate on data
Store console data, keyword position tracking and conversion analysis feeding a continuous testing cycle. ASO rewards iteration more than most channels.
Both stores, plus the web search before them
Most ASO providers work one store and ignore web discovery entirely. That leaves a large share of the opportunity untouched.
Per-store strategy
Apple and Google rank differently and we work them separately. Copying one listing across both is the most common ASO shortcut and it leaves ranking unclaimed in each store.
Web SEO included
Landing pages, app indexing and deep linking, because a large share of discovery starts on Google. Pure ASO providers simply do not cover this.
Creative testing as standard
We test icons and screenshots for conversion rather than treating creative as a design decision. Conversion feeds ranking, so this compounds in both directions.
Compliant review practice
In-app prompting within both stores’ policies. Incentivised or gated reviews risk removal from the store, which costs far more than slower rating growth.
Reported on installs and CAC
Organic installs, blended acquisition cost and retention — the metrics that determine unit economics rather than keyword positions alone.
Continuous iteration
ASO rewards testing more than most channels because feedback is fast and isolated. We run a standing test cycle rather than optimising once.

Keyword positions explain it. Installs and CAC are the result.
We report the metrics that determine whether your acquisition economics work, with store-level diagnostics behind them.
Organic installs
Installs attributed to store search and browse rather than paid campaigns, separated per store.
Blended cost per install
How organic growth shifts blended acquisition cost — the number that decides whether unit economics work.
Keyword rankings per store
Position on target terms in Apple and Google Play separately, since they move independently.
Store conversion rate
Impression-to-install conversion, which drives ranking as well as volume and responds strongly to creative testing.
Rating & review velocity
Rating trend and monthly review volume, which affect ranking and install conversion simultaneously.
Four stages, then continuous testing
Metadata first because it is fastest, then creative and web presence where the compounding happens.
Audit
Store listing teardown against competitors, keyword research per store, creative and conversion analysis, and web discovery assessment. You get a prioritised plan across both stores.
Optimise metadata
Title, subtitle, keyword field and description engineered per store. Fastest measurable win in ASO and usually where the first ranking movement comes from.
Test creative & build web presence
Icon and screenshot testing for install conversion, plus indexable landing pages, app indexing and deep linking to capture web-originated discovery.
Iterate
Store console data and keyword tracking feeding a continuous test cycle, alongside the rating and review programme. ASO compounds through iteration more than most channels.
