Which geolocation marketing technique involves targeting users based on their proximity to a specific location?

The geolocation marketing technique that involves targeting users based on their proximity to a specific location is 'proximity marketing'. Proximity marketing uses technologies like GPS, Wi-Fi, and Bluetooth to identify users who are within a defined radius of a particular point of interest, such as a store, restaurant, or event venue. For example, a coffee shop might use proximity marketing to send a special offer to users who are within a block of their location, encouraging them to come in for a drink. This differs from broader location targeting, which might target users in a city or region regardless of their specific location at that moment.
