What is Four Square? It's an app that is growing with popularity that allows users to check in at local businesses. Why would a user check in? To tell their friends where they are, what they're doing, the meal they might be having, their favorite coffee. And users also get rewarded by earning badges, becoming a mayor, becoming experts.
If you own a business and have a web presence you probably are already part of Foursquare. But, like most sites where your business listing shows you need to claim your business on Foursquare before you can interact with your customers and receive demographics regarding those customers.
You can also set up specials to reward customers for checking in with your business. Customers who check in reward your business with word of mouth recommendations that often get shared across Facebook and Twitter accounts.
And the best thing about this is that all it costs is the time to set it up, claiming your business, and setting up the special. For more information click here.
