To start, Facebook Check-Ins provide all the information a potential first-time visitor would require - your location, ratings, and a link to your Facebook page for more details. If a check-in is viewed on mobile, clicking the map will even bring up driving directions. More importantly, Facebook Check-Ins serve as a personal referral from one friend to another. The single most effective way to get a new member through the door is a personal ask. By checking-in, a Facebook user is making a point of telling her friends where she is. And people don't take the time to share a place they've visited unless they think their friends are interested. That's a far more valuable recommendation than any form of advertising could provide, simply because it's coming from your community rather than directly from you.
