An app that launches quietly rarely stays quiet for long, it just stays invisible. Building the product is the easy half of the work. Getting it to surface when someone searches the App Store or Google Play is a separate discipline called app store optimization, and most small teams skip it entirely once the app ships. That is the gap this guide closes: the parts of app store optimization a small business can control directly, without hiring a paid user-acquisition specialist or running ad campaigns.
App store optimization is not a single setting you switch on. It is a set of metadata decisions, covered below, that both Apple and Google use to decide whether your app matches a searcher’s query and whether it earns a spot near the top of the results.
What app store optimization controls
Apple and Google both run their own internal search algorithms for the App Store and Google Play, and neither company publishes the full ranking formula. What they do publish, through their own developer documentation, is which fields feed that algorithm: the app title, subtitle or short description, the keyword field (Apple only), the full description, category, and behavioural signals such as install rate, uninstall rate and ratings.
None of this replaces a product people want. An app store optimization pass on a weak app just gets a weak app found faster. For an app that already earns good reviews and repeat use, a poorly filled-in listing is often the only thing standing between it and new users searching for exactly what it does.
The title and subtitle carry more weight than most builders realise
Apple limits the App Store name to 30 characters and gives a separate 30-character subtitle field, both indexed for search. Google Play allows a 30-character title too, plus an 80-character short description that Google’s algorithm parses too. Cramming a brand name and five keywords into that space usually reads as spam and gets ignored, sometimes rejected, by both platforms.
The stronger pattern for app store keywords: brand name first, then one clear phrase describing what the app does, placed in the subtitle or short description rather than the main title. “Dominate Tasks: Simple To-Do List” tells a searcher and the algorithm what the app is in four words, which does more for ranking than a title stuffed with synonyms.
Keyword fields and descriptions still matter
Apple’s App Store Connect gives every app a 100-character keyword field that never appears to users but feeds directly into search matching, documented in Apple’s own App Store product page guidance. Repeating a word across the title, subtitle and keyword field wastes characters. Google Play has no separate keyword field, so the full description carries that weight instead, and Google’s own Play Console help states that keyword stuffing a description can get a listing suppressed rather than boosted.
A short aso checklist that covers both platforms without duplicating effort:
- List every real search term a user might type, not just the ones your team would choose
- Split them across the title, subtitle or short description, and Apple’s keyword field, so nothing repeats twice
- Write the first two sentences of the full description as a plain answer to what the app does, since both stores weight the opening lines more heavily
- Update the listing when a new feature matches a term people are already searching for, rather than waiting for the next major version
Screenshots and preview video decide the click, not just the rank
A listing can rank on page one and still convert badly if the screenshots do not show the app doing the thing someone searched for. The first two screenshots do most of the work, since that is what shows in search results before a user taps through. A screenshot of a login screen or a splash page wastes that space. A screenshot of the core feature in use, with a short caption, does not.
This is where the work overlaps with the build itself. If an app was built through Dominate Online’s app design and development service, the same design assets used in the product often need little rework to become store-ready screenshots, worth raising with whoever built the app before commissioning a separate screenshot set from scratch.
Reviews and ratings, without breaking either platform’s rules
Both Apple and Google confirm that ratings and review volume factor into search ranking, not just conversion. Buying reviews or offering incentives for them breaches the App Store Review Guidelines and Google Play’s developer policies, and both platforms actively detect and remove manipulated ratings.
The compliant version is simpler than most teams assume: trigger Apple’s native RequestReview prompt or Google Play’s In-App Review API after a moment where the user has just succeeded at something, not on first open. A prompt fired the instant someone opens the app for the first time gets dismissed almost every time. One fired after a completed purchase or a saved result gets answered far more often.
Where app store optimization stops and paid acquisition starts
App store optimization is a hard area to rank in organically once a category has established competitors already running paid search-ads campaigns inside the App Store and Play Store. That is a separate, budgeted channel, not a metadata fix, and treating the two as the same thing usually means underfunding both. The checklist above is the foundation that makes every other acquisition channel work harder, paid or organic, not a substitute for them.
Teams that reached this stage after weighing native versus cross-platform development or after scoping an MVP build before a full release tend to share the same blind spot: the store listing gets built in the last week before launch, by whoever has time, rather than treated as its own deliverable with its own owner.
Frequently asked questions
Why did my app’s ranking drop after I added more keywords to the description?
If the added keywords do not match what the app does, both platforms can read the change as manipulation rather than optimisation, and installs from mismatched search terms raise the uninstall rate, which both algorithms weight against the listing. Add keywords only where they describe a real feature.
Does changing the app icon affect app store optimization?
The icon is not a ranking factor on either platform, but it directly affects the click-through rate from a search result, and click-through is one of the behavioural signals both algorithms do weight over time. Treat icon testing as a conversion task that indirectly supports app store optimization.
Can I use the same keyword field content on both the App Store and Google Play?
No. Apple’s 100-character keyword field is invisible to users and separate from the title, while Google Play has no keyword field at all. Its ranking draws from the visible title, short description and full description. A strategy built for one store’s mechanics needs adapting, not copying, for the other.
How often should I update my store listing once it is ranking well?
Revisit it whenever a new feature matches something people are already searching for, or roughly every quarter at minimum, since both platforms treat stale, unchanged listings as a mild negative signal against actively maintained ones.
Do keyword tools built for Google Search work for app store keywords?
No. App store search behaviour and volume differ from web search, and a term with strong web search volume can have negligible in-store search volume, or the reverse. Each platform’s own search suggestions and autocomplete are the closer proxy.
