Short answer
It depends which language you mean. To change the language you see in Google Ads, use Preferences. To change who sees your ads, edit language targeting in the campaign settings.
Change your display language
- Go to Preferences in your Google Ads account.
- Expand Display language & number format and pick a language from the Display language menu.
- Select Save. By default, Google Ads uses your Google Account language. This setting does not change how people see your ads.
Change the language your ads target
- For a new campaign, enter a language in the search box under language settings, tick it, then click Save and continue.
- For several campaigns at once, go to Campaigns, open the Settings tab, tick the campaigns and choose Change languages from the Edit menu.
- Google may show an ad in a different language from the search if it is confident the user understands the ad’s language.
What changed in September 2026
Google removed the campaign-level language setting for Search campaigns. Search ads now match on the language of the ads themselves. In Performance Max, language settings still cover YouTube, Display, Discover and Gmail, but no longer to the Search Network.
In practice
App campaigns ask for languages at setup and build ads from your text and store listing. Localise both, so each language gets matching copy and screenshots.
