Geotargeting is when certain people within an area are targeted. Geotargeting is important for brick and motar companies to use because they usually serve a particular radius from their physical location. Smaller businesses that serve a specific audience can also benefit from geotargeting, and can generate more foot-traffic to their location.
Some social media platforms enable geotargeting. For example, Instagram allows you to post your location for every photo and video you u post. This is allows users to know where you are, without having to leave your Instagram Account.
