Geo-fencing allows you to target people in a specific location by drawing a virtual boundary around that area. When someone enters that location with their mobile device, they can see your ads. This is helpful for promoting offers that are meant for local audiences. For example, if a business is running a special deal in one city, geo-fencing helps make sure only people in that city will see the ad. It can also be used around events, stores, or landmarks to catch attention at the right time. To make it work well, you need to create a clear offer and link it to a strong landing page. Have you tested geo-fencing for your campaigns?
