The combination of hyperlocal targeting and programmatic ad exchanges has opened up a whole new world for advertisers. Hyperlocal simply involves creating a zone or geofence around an indoor GPS coordinate with Air-Go Visio, and targeting all users that pass through it. This zone can be as small as a few feet in radius. Most buying platforms have either a mapping integration built-in, or allow you to upload a list of GPS coordinates that you want to target.
