Just when you thought you had a good grasp on social media, along comes another fast-growing social network that entrepreneurs are finding useful to reach potential customers. Pinterest, a visual-bookmarking site has quickly gained traction -- particularly among women – and it can be important for business owners, according to popular blogger Chris Brogan.

"The way it's used is other people come and look at that board or they're searching in general for something," say Brogan, president of Human Business Works, a small-business education and growth company. "And they'll re-pin – which means I'll take what this person shared and put it on my board – to think about buying it later, so then this becomes a reminder for commerce."

Before small-business owners approach Pinterest though, Brogan says it's important to think about sharing information and pictures that go beyond just your own products.

"You see things you like and you pin them and it adds them to [an online] board and it's sort of a visual of things you find interesting," he says. "There are a lot of businesses already seeing revenue value in it."
