I have a facebook for my shop and a blog. I created my blog way before opening my etsy shop but I've added an etsy mini to it now.
I know people use twitter to promote too.
Create treasuries, not adding your items of course. Send a convo to the ones you have included, they will visit your treasuries and probably your shop too. If they like it they could add you to their favorites and you will be featured in their treasuries :)
Join teams. There are great people around Etsy and we help to promote each other.
ok, I don't know what else...you need to promote a lot to bring traffic, promote here, with friends, whit people you know, etc.
Good luck ♥
