Zhao is launching a marketing initiative to reach both Englishand Portuguese-speaking countries. How should he most effectively set up Google Display ads?

Google Ads applies location targeting and language targeting at the campaign level, so the cleanest structure is to separate markets by campaign. This gives better control over market-specific settings, budgets, and reporting for each country or region. It also makes localization easier because each campaign can be aligned to the language needs of the location it serves. Using ad groups for this setup is less appropriate because ad groups organize ads and targeting inside a campaign rather than replacing campaign-level geography controls
