Ad language and location targeting can only be set at the campaign level for Performance Max campaigns.
Microsoft Advertising Support may not be available for all languages.
Microsoft Advertising's language targeting allows you to target your ads to particular web searchers based on your specified ad language. Microsoft Advertising uses several signals to determine whether your ad will display to a potential customer based on the ad language you set, including query language, publisher country language, and the potential customer's language setting. For a list of languages your ads can serve in, see About language options in Microsoft Advertising. For a list of countries/regions where your ads can display, see Market availability for Microsoft Advertising and its features
Here are the steps you take to determine where your ads are shown:
*Note:
*Coordinates can be searched for in the format "[latitude], [longitude]" with the degrees in decimal form — for example, "44.590,-104.716".
Microsoft Advertising will honor your location targeting settings and exclude locations you don't want to target. However, location targeting and exclusions may not always work because of factors beyond the control of Microsoft Advertising, such as a customer's device settings or the inherent limits of geolocation via GPS, IP addresses, Wi-Fi networks, and Bluetooth.
When the feature is enabled, your campaign languages will match the languages of all the ad groups in that campaign by default. For example, if a campaign has three ad groups with language set to English, German, and French, then the campaign languages will be set to English, German, and French. You can subsequently change this setting. If you want the campaign to target multiple languages, you can update the ad groups using the Use my campaign settings option. (Note: If all of the ad groups in a campaign are set to the same language, then enabling this feature will not affect the campaign's language setting.) You can still have an ad group level language setting if you want the ad group to target one specific language. The ad group language, if set, will override the campaign settings. If there is no ad group language, then all the campaign languages will apply to the ad groups.
Both the location targeting criteria and the language setting criteria must be met in order for an ad to be eligible for display. Of course your other targeting settings, beyond location, will also have an impact on the determining if the ad should be shown to the searcher.
For example, let's say you set your ad language to German. Because your ads are specific to a market, you decide to select your location target to Berlin, and even more specifically, show your ads only to people in your targeted location. Now, your ads will only show to searchers physically located in Berlin. For more information about targeting, see How can I get my ads in front of my customers?
