What is Geo-Fencing?

Geo-fencing is location-based ad targeting that draws a virtual boundary around a real-world area — a ZIP code, a radius around a store, or a competitor’s location — and serves ads to devices inside it. It lets local businesses pay only to reach people near enough to become customers.

Geo-fencing is foundational for local streaming TV: a restaurant can target only the neighborhoods it serves, and a dealership can reach households within its driving radius.

Modern geo-targeting uses privacy-conscious location signals rather than tracking individuals, and combines geography with demographic and interest layers for precision.
