Microsoft Advertising Support may not be available for all languages.
Three language options in Microsoft Advertising give you control over your advertising campaign and experience.
Language options can only be set at the campaign level for Performance Max campaigns.
Your campaign ad language determines the language that you will use when you write your ads and should be the language of your customers.
You can choose an ad group-level language when you create an ad group. If there is no ad group language, then all the campaign languages will apply to the ad groups.
Your ad language, in combination with your location targeting, determines who will see your ads. To learn more, see How does ad language and location targeting affect who can see my ads?
Your billing language determines the language of your billing documents. This setting is per account and doesn't apply to other Microsoft Advertising accounts you may have.
The following billing languages are supported: Danish, Dutch, English, Finnish, French, German, Italian, Japanese, Norwegian, Portuguese, Spanish, Swedish, and Traditional Chinese.
Your display language determines the language of the email notifications and other account messages you receive, as well as the language of the Microsoft Advertising interface and help content.
The following display languages are supported: English, French, German, Italian, Portuguese, Spanish, and Traditional Chinese.
