It's exciting to help a business grow via social media. I'm currently assisting a local business with over 30 years of experience grow via social networking. I love hearing that customers are enjoying the emails full of tips, deals, and information.
When coupons posted on the blog or website are brought in, or a sale is made because the product was posted on the web and when the traffic into the physical location is increased----in this economy---it is a great thing.
Providing value through the blog, Facebook, Twitter; solving customer's problems when the customer had no idea a solution existed--enhancing the customer experience, making life easier, and, yes, generating additional sales; it's great.
