To create a targeting profile by Language, first select Language from the conditions drop-down menu. If the “Inverse Condition” box is checked, then the ad or ad group will NOT be served to browsers using that Language.
The language condition looks for the ISO 639-1 language code in the language string of the browser. The language string contains the language codes for all enabled on the user’s browser list in preference from left to right, with the left most language code being the preferred language of the browser.
You can target by either contains, empty, Regex, or preferred.
To target a language contained in the language string, choose “contains” from the drop-down menu and type in the alpha code of the language you want to target (i.e. fr for French). To target the preferred language of the browser, choose “preferred” from the drop-down menu, and enter in the partial carrier or ISP name. The language field is NOT case sensitive, for example, entering fr in the language field will match FR, Fr, fR, or fr. You can also target languages with local variations, for example, en-US for United States English.
Click the “Add” button to add the targeting condition to your ad or ad group. Then click the “Save and Close” button to save the targeting profile.
When you use language targeting on an ad or ad group, you must have a backup ad or ad group that will be served to users that do not meet the language conditions you have set.
Any conditions added to the same profile will be AND conditions, meaning that all conditions must be met in order for the ad or ad group to be served. To create OR conditions, you will need to create a new targeting profile. If there is more than one profile, then all conditions in Profile 1 must be met OR all conditions in Profile 2 must be met, etc. for the ad or ad group to be served.
