You've set up a Facebook page - why aren't you using it?  No time to create content?  That's why we're here.

It's important to engage with your customers and fans on the social media pages you've set up.  Social media sites are "the" places to hang out, so you need to be there, too, with interesting content about you and your business.  You want content that is liked and shared.  You want content that generates comments.  You want content that brings you and your followers closer together.
