Browser Language Targeting allows you to reach users by language. Specifically important in countries where people speak different languages and you want to target them with individual campaigns. Your campaign will then be selected depending on the language set in the user's browser. Several values can be set per campaign and combined with other targeting options.
Example 1: Target Spanish-speaking users in the USA:
Select "Spanish" from the dropdown. This will cover all specific browser language combinations for Spanish.
Also set "United States" under Locations
Example 2: Target French-speaking users in Switzerland:
Select "French" from the dropdown. This will cover all specific browser language combinations for French.
