What languages should I target in Google AdWords?

Generally speaking, the language you target in Google AdWords should be the same language as the language used in your ad. You’ll naturally want your audience to be able to read your Google ad, so language targeting is critical to a successful Google AdWords campaign.

Any advertiser wants the audience to speak the same language as the language used in an ad. In addition, since Google ads usually contain the keywords being searched at that moment, you’ll want the ad language to match the keyword language.

Thus, Google AdWords allows you to choose the language of your audience. You’ll set your preferred language in the Google AdWords settings, and Google AdWords will then determine to whom your ad will be shown based on the user's Google domain, their search term, their computer's IP address, and their language preference set for Google. All of this ensures that your audience will be able to read your Google ads.
