My wife has a store on Etsy and does very well. She also sells alot on Ebay. To get the folks to what she sells, she does alot of social media stuff like blogs, twitter, facebook, Pinterest, etc. When someone buys from her, she asks them to post something for her too.
The way we explain social media to folks is you can setup the best site with great deals on it, but if they don't know it's there, it would be a miracle they find you, so you need to talk it up everywhere.
