App Store vs Google Play ASO: What Actually Differs

Developers who ship to both stores usually write one listing and paste it twice. It is an understandable shortcut and it costs real installs, because the two stores read your listing in fundamentally different ways.

The field-by-field comparison

That table contains the whole argument. On the App Store you have roughly 160 indexed characters. On Google Play you have roughly 4,110.

What this means for how you write

App Store: compress

You are working with a character budget so tight that every word must earn its place. The discipline is closer to writing a headline than writing copy:

• One primary keyword phrase in the name, alongside your brand
• A distinct secondary cluster in the subtitle, with no word repeated from the name
• Everything else in the keyword field, comma-separated with no spaces, singular forms only

Your description is then written entirely for conversion, because it does nothing for ranking. First two lines carry almost all the weight — that is what shows before the “more” tap.

Google Play: write naturally, then check frequency

The full description is indexed, which means you have room to cover many more terms. It also means Google’s spam detection applies, and it is not subtle.

Aim for each target keyword appearing two to four times across the description, in sentences a human would actually write. Google’s metadata policy prohibits keyword stuffing outright, so beyond that you enter diminishing returns and then active penalty.

Structure that works:

1. One-sentence hook that repeats the title’s core promise
2. Feature list — natural home for secondary keywords
3. Use cases — natural home for long-tail phrases
4. Social proof — awards, press, install counts
5. Short closing paragraph with the primary term once more

The 80-character short description is heavily weighted and appears above the fold. Treat it with App Store levels of care.

Ranking signals that differ

Ratings and reviews matter on both, but Google Play weighs review recency more heavily and reacts faster to rating drops.

Install velocity matters on both. Google Play weighs conversion rate from the store listing more explicitly — impressions to installs is a signal, which makes screenshot quality a ranking factor and not only a conversion factor.

Technical quality is a Play-specific signal with real teeth. Crash rate and ANR rate feed Android vitals, and poor vitals demonstrably suppress visibility. The App Store has no public equivalent.

Retention matters more on Play. Uninstall rate is a signal.

In-app purchase names are indexed on the App Store and not on Play. If you sell subscriptions, naming them with keywords in mind is free App Store coverage that most developers never claim.

Localisation differs too

App Store: each localisation gets its own keyword field, and some locales inherit from others. Setting English (UK) and English (Australia) separately from English (US) gives you additional independent 100-character fields targeting the same language.

Google Play: localisation is per-language rather than per-country, so there is no equivalent inheritance trick. What matters instead is that Play translates search intent less aggressively — non-English markets often reward listings written natively rather than translated.

Timing differs

• App Store: metadata is re-indexed within one to three days of a release going live. Keyword field changes require a new version submission.
• Google Play: re-indexing takes anywhere from a few days to two weeks, but store listing text can be updated without shipping a new APK or bundle.

That second difference is practically significant, and it changes how long you wait for results. On Play you can iterate on listing copy without a release cycle. On the App Store, keyword changes ride along with a build, so batch them with a version you were shipping anyway.

What transfers and what does not

Transfers: your keyword research method, your competitor list (mostly), your understanding of which terms your users search for.

Does not transfer: the actual volume and difficulty figures, the placement strategy, the writing style, and often the competitive set. An app that dominates a term on the App Store may be absent from Play entirely.

Research each store separately. Sharing a candidate list is fine; sharing conclusions is not.

A practical workflow for both

1. Research keywords per store and per country.
2. Write the App Store fields first — the tightest constraint forces the clearest thinking about your primary term.
3. Write the Play title and short description using the same primary term.
4. Write the Play long description as natural copy, then check that each target term appears two to four times.
5. Write the App Store description last, purely for conversion, with the first two lines doing the work.
6. Track the same keyword set on both stores so you can see where the same term behaves differently.

ASOnest treats both stores as first-class in one workspace — one keyword list, one rank chart, one competitor view, with the tokenisation and character rules applied per store. Every plan includes all countries and starts with a 7-day free trial.
