If an advertiser is trying to set up Google Display ads to reach both English and Spanish-speaking countries, how should they structure them in Google Ads?

Google Ads applies location targeting and language targeting at the campaign level, so separating markets by campaign gives the cleanest control. This structure makes it easier to manage delivery, budget, and reporting for each country or region independently. It also supports localization, because each campaign can align its ads and settings to the users in that market. Using ad groups for this would be less effective because ad groups organize targeting and creatives inside a campaign rather than replace campaign-level geography controls
