Google Ads location targeting allows your ads to appear in the geographic locations that you choose: countries, areas within a country, a radius around a location, or location groups, which can include places of interest, your business locations, or tiered demographics.
Location targeting helps you focus your advertising to help find the right customers for your business. By default, your ads can show to people in, regularly in, or who've shown interest in your targeted locations.
You can also select locations to exclude from your campaigns if you don't want your ads to show in specific regions.
