Foursquare introduced post check-in ads during the summer, and brands have been giving the promos a healthy test run since.
Adweek has collected a handful of examples of how the mobile advertisements are targeting consumers by location and general interest. Think yuletide beverages at your local grocer or a healthy thirst-quencher while at the gym.
Indeed, while Foursquare also offers a search/explore ad product, these demonstrations showcase what kinds of branding the social-mobile platform can provide. Though how well they work remains an important question, expect consumer-packaged-goods companies to target in-store patrons with the nascent check-in promos in 2014.
