Looking for ways to increase their penetration in Location Based Services (LBS), Facebook announced yesterday that they’ve added an application called Deals to their platform. Currently only 4% of online adult Americans use LBS applications to let their friends know where they are throughout the day. As an incentive, Facebook has teamed with 21 businesses (so far) to offer deals to users who check-in to certain locations around their cities; Gap is offering a free pair of blue jeans to the first 10,000 people who check-in at a Gap location on November 5, 2010; Macy’s is giving shoppers 20% off for checking in; REI, Starbucks and 24 Hour Fitness are all offering to donate money to various charities for every check-in at their locations. These rewards are clearly more pragmatic and meaningful than the badges and titles that users on Gowalla and Foursquare have competed for up to now, and should provide greater incentive for the general public to at least start considering the use of LBS. Ultimately, Facebook needs to remove as many barriers-to-use of this LBS functionality as possible; the most powerful delivery method of these rewards will be the user simply collecting and storing their credits in a digital wallet, as opposed to “proving” that they’ve checked in to a store clerk before they can claim their discount at the point of sale. The user could then simply check-in at various locations and the store would instantly recognize their account and provide discounts automatically. What do you think about Location Based Services? Do you use them currently? Would you check-in for a free pair of Gap blue jeans?
