I wouldn't suggest using just Etsy to create a successful business. It's a great place to have your things, do your transactions through, etc, but it will not bring the customers to you. There are other sites out there, like EBay, where people find your items and buy them that way...you don't have to go out and show people your item to bring them in, but here you have to do that. That's where social media comes into play. I have my Etsy shop, a Facebook page, and I sometimes tweet using my items using my personal twitter. I also pin my items on pinterest. You will get a decent amount of views from Etsy if your SEO and tags/titles are good, but you should not rely on that if you want it to be a success.
