App Store vs. Google Play: ASO Differences You Need to Know in 2026

The metadata fields are completely different

This is the most important structural difference. The App Store gives you a dedicated 100-character keyword field that is invisible to users but indexed directly for search. You list comma-separated terms and Apple uses them as ranking signals — no repetition needed or allowed. Google Play has no equivalent keyword field. There is nowhere to list keywords out of view.

On Google Play, the long description (up to 4,000 characters) is your primary keyword surface. Google indexes it and uses keyword density and phrase coverage as ranking signals. A description that is too thin or generic leaves ranking potential on the table. On iOS, a long description that repeats keywords adds no ranking benefit — it is user-facing copy only.

Character limits and field weighting differ significantly

The App Store title is 30 characters. The subtitle is 30 characters. The keyword field is 100 characters. Every character in these three fields is valuable — there is no room for weak word choices. On Google Play, the title allows 30 characters and the short description allows 80 characters. The long description has 4,000 characters and Google actively indexes it.

• iOS title: 30 chars — lead with the strongest keyword and brand. Apple gives title terms the highest weight.
• iOS subtitle: 30 chars — extend the intent without repeating the title keyword.
• iOS keyword field: 100 chars — no spaces after commas, no repetition, use every character.
• Google Play title: 30 chars — similar importance to iOS title.
• Google Play short description: 80 chars — highly visible and indexed; include your primary keyword.
• Google Play long description: 4,000 chars — use full sentences, natural language, and keyword variety.

Localization, A/B testing, and indexing cadence

Google Play auto-translates your listing into other languages unless you provide a localized version. That translation is often indexed for local search. Apple does not auto-translate — you have to submit each locale manually, but when you do, each locale gets its own keyword field, which means your keyword surface multiplies with each language you add.

Google Play also supports store listing experiments natively, letting you A/B test screenshots, short descriptions, and feature graphics against real traffic. The App Store has no equivalent built-in experiment system. If you are running experiments on iOS, you are relying on third-party tools or manual release comparisons.

Indexing speed also differs. Google Play often picks up metadata changes within days, sometimes within hours for critical fields. The App Store can take one to two weeks to reflect ranking changes after a release, which makes the cost of a bad metadata decision higher and the iteration loop slower.

What should stay the same across both stores

Positioning, user problem framing, and screenshot messaging should be consistent. You are solving the same problem for the same person — the store format changes but the product does not.

Use Release Planner to draft platform-specific versions of your metadata side by side before submitting to either store. Use Competitor Compare to check how direct rivals handle each platform separately — it often reveals field usage patterns you have not considered.
