Facebook has a newer tool called Beacon. This device literally pings(sends a signal to) the devices that enter your establishment. From there it will open your visitors Facebook to your business page, once they click on that app within their device. At that point your visitor gets some reasons to engage with you & share your business. Take a look at the description in the graphic below. Facebook is offering a limited rollout right now, so if you’re offered a Beacon on your business page, go for it! It will be an invaluable tool for engaging with visitors on Facebook, and you’ll be ahead of the curve!
