I just read an article by Stephanie Mills on the AMEX Open Forum under Social Media about how you can use Foursquare to drive repeat business...for FREE!
is your small business on Foursquare? Have you claimed your venue? If you do, Foursquare will send you window clings to encourage people to check in when they visit your business. Not only does Foursquare give you the tools to see who is visiting your business and when, but they also give you the tools to reward those that do. There are more than 15 million people using Foursquare to check in, earn badges, share with their friends on Twitter and Facebook to where they are.
There are 500,000 businesses using Foursquare, you should be too!
