I don't have an Etsy store but if I did, I wouldn't depend on their incidental traffic for buyers because many people still have never heard of it. If you have a good plan for advertising I can see how Etsy would be a helpful vehicle for actually closing the sale and handling logistics, but attracting buyers is something I would treat as a separate endeavor.
I've made several Etsy purchases but only one or two were items I actually found there; all the others were items I saw or read about somewhere else, and just went to Etsy to buy.
Does that make sense?
