How Do I Run Meta Ads in Multiple Languages?

You can add languages to a single ad in Ads Manager: one default language plus up to 48 more, each with its own headline and primary text. Meta says this means you do not need a separate ad set and language targeting for each language. If you choose no language at all, Meta delivers to people its systems predict can understand your creative. This is as checked on 2 Oct 2026.

What is the difference between language settings and multi-language ads?

They solve different problems.

• Audience language setting. Optional. Meta says to choose a language only if you want to reach people who understand a language that is not widely spoken in your selected location. Its example is people in the US who understand French.
• Multi-language ad. One ad carries several versions of the text, and each person sees the version for their language. Meta calls this dynamic language optimization.

If you are advertising in one country in the main local language, you may need neither.

How does Meta decide who understands your ad?

Meta says its delivery system predicts language preferences from signals such as a person’s location, groups they have joined, posts they have created, liked or commented on, device and browser settings, ads they have interacted with, and people they follow or who follow them. It does not guarantee accuracy: you may see impressions, messages or leads from outside your language settings.

So the creative and the landing page must match. Meta tells you to make sure both match the languages you plan to choose.

How do you add languages to one ad?

Meta’s steps for the multi-language ad, in short:

1. Enter your ad text and links in your default language.
2. In the languages section, select add languages, pick the default language, then add up to 48 more.
3. Enter a headline and primary text for each extra language. You can add a new image for each language too.
4. After publishing, break down your reporting by language to compare them.

If you cannot turn on languages in Ads Manager, Meta says the feature is unavailable to you. It also says the feature is gradually moving from languages to a new translations step in the ad creative.

Where does it not work?

Meta lists several cases. Dynamic language optimization is not available with partnership ads, Advantage+ sales campaigns that use Advantage+ creative, or Instant Experience and messaging app destinations. Dynamic creative is not compatible with it. If you use placement customization too, you can have up to 4 placements and 11 languages, not 48 extra ones.

Check your campaign setup against that list before you plan one ad for every language.

What about AI translations?

Meta’s generative AI translations can translate your text, voiceovers and image overlays into the audience’s preferred language. Text translations cover single image, video and carousel ads, and you cannot edit the translated text. Meta lists supported language pairs, such as English to Spanish, and says text, voiceover and overlay translations are not currently available in South Korea and not in all regions or languages.

Meta says text translations and dynamic language optimization have similar functionality, so it recommends using only one of them. Meta says an older automatic translations feature is gradually being removed.

FAQ

Do I need a separate ad set for each language?

Not necessarily. Meta says an ad that displays in multiple languages means you do not need various ad sets for each language and separate language targeting. Check the exclusions first: some objectives, destinations and ad types do not support it.

Should I choose a language in the audience settings?

Only in particular cases. Meta says choosing a language is optional, and to use it only to reach people who understand a language that is not widely spoken in your selected location. Otherwise Meta predicts who can understand the language of your creative.

Can I trust automatic translations?

Review them. Meta says of its older automatic translations that it does not guarantee quality and recommends you review all translated text. They are not available for ads about social issues, elections or politics. Have a fluent reader check any translated text before you publish.
