Foursquare is more than just a technique for selling cars....it’s an ever-growing social site that lets people check in at locations on their smartphones and claim specials. Foursquare and other location-based marketing sites like Gowalla and SCVNGR have been growing in popularity as more and more people use smartphones. Auto dealers need to take advantage of these sites to promote service discounts and other offers, driving people to check in at the dealership. It's simple to claim your dealership's venue and beginning offering specials to get more customers coming in.
