The launch of Facebook Deals saw a flurry of brands tipping their toe in the location marketing waters. Many brands have tried check in offers on Foursquare, and whilst the likes of Dommino’s and McDonalds have reported a good response, there seems to have been no real measure of it. The questions still remain: how many more people, and how mandy more sales can a check-in offer generate?

Foursquare is addressing this, by working with the NFL on the forthcoming Superbowl. They have created a Super Bowl Sunday badge, and fans checking in will be given a code that they can redem it for a 20% discount at the NFL online shop. Clearly, one campaign will not be enough to give true figures, but when it comes to marketing response we are generally looking at a range of ROI or uplift. Foursquare say this is an experiment and they are not getting any revenue from it – looks like their revenue model has still not been found!
