Today there are more than 800 million Facebook users, more than 200 million people on Twitter and more than 130 million on LinkedIn.  It's safe to say social media is changing how we live. It's even changing how CEO's market their products.

Clara Shih is a CEO herself -- the woman behind Hearsay social, one of the first companies that helps businesses market themselves on social media sites like Facebook, Twitter and LinkedIn.

Shih's idea was to build a business application on Facebook. She was the first to do it. She wrote the bestselling book "Facebook Era." Two years ago she started a business in her apartment. Now she has more than 40 employees.

"Working for Clara, it's firing on all fronts," says Kristin Shevis, who is Shih's Director of Sales.

"She's the kind of person that when she's successful, she brings other people up with her," says Ally Russel, who is Shih's Head of Compliance.

So what are Shih's simple secrets for business success? Find a great mentor, make moves when the time is right and surround yourself with a winning team.

"We just want people to work hard and play hard," says Shih.

Fifty-four percent of Fortune Global 100 Companies already have a presence on Facebook, but Shih says one common mistake businesses make is not understanding the social media they are trying to use.

She says make sure you claim your page so you have control of your brand! Also, get local. For retail it might mean exploring check-ins by offering promotions. To acquire more fans, include a link to your social media page in your email signature, asking people to "like" it. But she adds, always tell them why they should like it.

Shih says she has only one regret. "I wish I would have started sooner!"
