Geotargeting allows you to refine your campaign by targeting specific Canadian geographic locations, including province, cities, and Postal Code (by first 3-digits, or Forward Sorting Area).
Enabling geotargeting
You can enable geotargeting in the ad group setup page and in the Asset Library (when building a rule-based custom audience).
Navigate to the Location section of the ad group setup page. By default, it's set to All locations within Canada.
