Foursquare offers free tools to help you attract new customers and to keep the existing customers engaged. With the help of “Save to foursquare” button on your group, visitors can easily get foursquare reminders from you when they are near the places that you suggest. This button is very easy to setup. When one of your group visitors clicks on the “Save to foursquare” button on your group, your group is saved on their to-do list in foursquare. Then, when they’re out and about, foursquare Radar will buzz on their phone when they’re close to it.
