In internet marketing and geomarketing, the delivery of different content based on the geographical geolocation and other personal information is automated. A good example is the Ace Hardware website at www.acehardware.com. The company utilizes geolocation software to power the “My Local Ace” section of its website. Based on a site visitor’s location, the website's online locator service can show the visitor how many stores are in their area, as well as a city-level locator map to help the customer find the store closest to their address.
Beacons are little physical objects (under two square inches, in most cases) that can be placed in desired locations. Their sole purpose is to detect you, or more specifically, your device, as you move into their range. The beacons themselves don’t send content. Like geofencing, a signal is triggered when you’re near one, and a server sends a push, text, in-app message, or even an email (though currently, that’s a less likely application for beacons).
