Geofencing
01 Definition
Geofencing meaning: Setting a virtual boundary around an area to target ads to devices inside it.
Geofencing uses GPS, Wi-Fi, or other location data to draw a boundary around a place, then serves ads to devices that enter or sit within it. Advertisers use it for local reach around stores or events. Accuracy depends on device settings and available location signals.
Why it matters
How Geofencing fits the work
It lets local advertisers focus budget on people physically near a location, which can lift relevance for foot-traffic driven businesses.
In context
A coffee shop geofences a one mile radius around its store so nearby phone users see a lunchtime discount ad.
Practical note
Location accuracy is imperfect, and users can opt out of location sharing. Very small radius targets may limit volume and raise costs per result.
