Where your ads should appear is important—but where they shouldn't appear is just as important to your campaign's success. Learn how to exclude specific geographic locations from your ad campaign by following the steps below:
Login to your Google Ads account.
Find your campaign.
On the left hand side under Overview, click on Locations > Excluded.
Click on the blue pencil icon or + Edit Locations to set up your excluded locations.
Once you Save, the excluded location(s) would appear in the list (screenshot below).
