App Store vs Google Play ASO: The Key Differences (2026)

If you're shipping to both iOS and Android, it's tempting to copy your store listing from one platform to the other and call it done. That's a mistake. The Apple App Store and Google Play index, rank, and reward metadata in fundamentally different ways, and a listing tuned for one can leave rankings on the table on the other. This guide breaks down app store vs Google Play ASO field by field, so you can optimize each store on its own terms.

The single biggest difference in one sentence: Apple uses a hidden keywords field and ignores your description for ranking, while Google Play has no keywords field and crawls your title and descriptions for keywords instead. Everything else — titles, character limits, ratings weighting — follows from that split. For the fundamentals that apply to both, start with our pillar on ASO for indie developers; this post is the head-to-head comparison.

The core difference: how each store finds keywords

App Store Optimization is really two questions: what terms does the store associate with my app, and how does it rank me for them. The two stores answer the first question in almost opposite ways.

Element	Apple App Store	Google Play
Keywords field	Yes — hidden 100-char field	No dedicated field
Description indexed for ranking?	No	Yes — a primary signal
App name / title length	30 characters	30 characters
Subtitle / short description	Subtitle, 30 chars (indexed)	Short description, 80 chars (indexed)
Full description role	Conversion only, not ranked	Ranked and conversion
Keyword repetition	Avoid — each term once	Helps — natural repetition matters

On Apple, you're placing keywords like a surgeon: each unique term goes once into the name, subtitle, or the 100-character keywords field, separated by commas with no spaces. Repeating a word wastes precious characters — Apple already knows it. Your description is purely for persuasion.

On Google Play, you're writing for a crawler. There's no keywords field, so Google reads your title, short description, and full description to decide what you rank for. Natural repetition of your primary keyword across those fields (without stuffing) is a genuine ranking factor.

Titles and names: same limit, different tactics

Both stores cap the app name at 30 characters, but they use it differently.

Apple: The name is your strongest ranking asset. A common pattern is Brand: Primary Keyword (e.g., "Habitly: Habit Tracker"). Pair it with a keyword-rich 30-character subtitle. Combined, the name and subtitle carry most of your keyword weight — see app subtitle vs promotional text for how to split them.
Google Play: The title is also heavily weighted, so the same Brand: Keyword format works. But because your descriptions also rank, you have more room to spread keywords beyond the title without cramming everything into 30 characters.

Avoid keyword stuffing in the title on either store — both have guidelines against it, and Google in particular has cracked down on titles overloaded with terms and emojis.

Descriptions: convert on iOS, rank on Android

This is where copying a listing verbatim hurts you most.

Apple App Store description

Because Apple doesn't index the description for keyword ranking, write it entirely for the human reading it. Lead with the benefit, use short scannable paragraphs, and drive toward the download. There's no ranking penalty for not mentioning your keywords here, and no reward for cramming them in. See how to write an app store description for structure.

Google Play descriptions

Google Play gives you two fields, and both matter:

Short description (80 characters) — indexed and shown prominently. Fit your primary keyword and core value in one line.
Full description (4,000 characters) — indexed and the visitor reads it. Weave your primary and secondary keywords in naturally, ideally repeating the main term a handful of times across the copy. Write for humans first, but don't waste the ranking opportunity.

Ranking signals beyond metadata

Metadata is only half of ASO. Both stores factor in behavior, but they weight it differently.

Signal	Apple App Store	Google Play
Download velocity	Strong factor	Strong factor
Ratings & reviews	Important	Important, and keywords in reviews can be indexed
Retention / engagement	Growing factor	Strong factor (Android exposes more usage data to Google)
Uninstalls	Indirect	Direct negative signal
Update frequency	Minor	Minor positive

The practical takeaway: Google Play leans harder on real usage data — retention, uninstalls, engagement — because Android gives Google more visibility into how people actually use your app. Apple weights the store-side signals (downloads, ratings, conversion from impression to install) more heavily. On both, a healthy ratings and reviews strategy compounds over time.

Screenshots and creative: the shared front line

Visual assets convert on both stores, but the specs differ, and Google surfaces some creative earlier than Apple.

Apple shows up to 10 screenshots per device; the first two or three appear in search results, so front-load your best. iPhone 6.9" screenshots are 1320×2868; iPhone 6.7" is 1290×2796.
Google Play shows up to 8 phone screenshots at 1080×1920, plus a 1024×500 feature graphic that can appear at the top of your listing and in promotions — Apple has no equivalent.

Because the sizes differ per store, produce each set at the correct spec rather than resizing one into the other. Adalo Studio's screenshot generator exports at each store's exact dimensions from one design, so your iOS and Android creative stay visually consistent without manual resizing — the screenshot sizes reference lists every spec. Studio's store-listing generator also produces separate metadata sets tuned for each store's model. Everything is free to design; you only pay a one-time unlock to export, laid out on the pricing page.

How to run ASO for both stores efficiently

You don't do double the work — you do shared research with platform-specific execution.

Do keyword research once. Build one prioritized list of the terms your audience searches.
Split the execution. Place those terms in Apple's name, subtitle, and keywords field; weave them into Google Play's title, short description, and full description.
Write two descriptions. A conversion-first version for Apple, a keyword-aware version for Google Play.
Produce creative per spec. Screenshots at each store's exact size; a feature graphic only for Play.
Track separately. Rankings, conversion rates, and keyword performance differ per store, so measure them independently and iterate.

Quick summary: App Store vs Google Play ASO

Keywords: Apple = hidden 100-char field, each term once; Google = no field, keywords live in title and descriptions.
Description ranking: ignored by Apple, primary signal for Google.
Behavioral signals: Google weights retention and uninstalls more heavily.
Creative: different screenshot sizes; feature graphic is Google-only.
Strategy: share the research, split the execution.

Optimize each store on its own model instead of forcing one listing onto both, and you'll rank better in both — for the same amount of research.

Frequently asked questions

What is the biggest difference between App Store and Google Play ASO?

The keyword model. Apple uses a dedicated, hidden 100-character keywords field and does not index your description for ranking, so you place keywords deliberately in the name, subtitle, and that field. Google Play has no keywords field and instead crawls your title, short description, and full description for keywords, so you write those to naturally repeat your target terms.

Does the app description affect ranking on both stores?

Not equally. On Google Play, the full description is a primary ranking signal, so keyword placement and repetition there matter a lot. On the Apple App Store, the description is not indexed for keyword ranking — it exists to convert visitors — so keywords belong in the name, subtitle, and keywords field instead.

Should I use the same ASO strategy for iOS and Android?

You should share the same core keyword research and brand positioning, but adapt the execution to each store. Reuse your keyword list, but place those terms in Apple's keywords field for iOS and weave them into the title and descriptions for Google Play. Treat titles, character limits, and metadata separately for each platform.
