Location-based advertising helps you reach people who can actually act because they are in the right place. You can target by city, ZIP code, or a tight radius around a location using signals like GPS, Wi Fi, and IP addresses. That targeting can drive sales, calls, bookings, and visits, but only when the page after the click matches the location and the next step is obvious. This guide breaks down the main types of location based advertising, explains geotargeting and geofencing, and shows which metrics matter when you want real outcomes, not polite scrolling.
