Social media.

As a business owner, the idea of it haunts you in your sleep.

You know you should be posting stuff, but you don't really have time. Plus, you're not sure even sure where to do it.

That changes today.

Want to learn what social media sites your business should be on? Read on and learn what works for what types of companies. Let's end those nightmares.

Facebook

What is it? Everything social rolled into one. Facebook has photos, messaging, chat, reviews, and more. People usually use Facebook for their personal lives rather than their professional lives.

Best for: local businesses, B2C businesses, ecommerce sites

A small company who's rocking it: The Village Toy Shop in Easton, Massachusetts has a great page for a small, local shop. They post info about product recalls, run giveaways and promotions, and publish photos of stuffed animals and blankies that get left behind in the store.

Note: Reddit is a network for individuals, not companies. If you create a cool resource, have some insight, or have something funny to share, it's a great place to do that.
