Google Play listing localization is more than translating the title. The store can show translated text and localized graphic assets when the user's language preferences match languages you add.
What you can localize
Google says you can add translations for your store listing, app strings, and in-app products. For the listing, that includes title, short description, and full description.
Graphic assets matter
Google also lets you add localized graphic assets. If you add text translations without localized graphics, the app's graphics show from the default language.
Machine translation caution
Play Console can provide machine translations for some languages, but Google notes that machine translations are not reviewed or approved by humans. Review them before publishing.
Source notes
Google's translate and localize documentation covers translated listings, localized graphic assets, automatic translation behavior, and machine translation caveats.
