Pay for etsy Search adds.
Promote your stuff on facebook.
Offer a coupon or gift card.
Use Twitter to tweet about new listings.
Get a professional banner for the storefront. And a logo.
Make sure your etsy store is linked to your Facebook, Pinterest and twitter and follow the above two rules.
Take clear and close up photos. Show the same item 3 or 4 different ways in the photo options so people can get a feel for it.
Keep your text in your listing sweet and short. People don't have time to scroll down to the bottom to read, they only read the first 2 paragraphs. And decide if they want the item based purely on the photograph and price.
Don't over price or under value your product. See what the same things cost on etsy, be competitive but not too drastic, people might think you are a fake.
Host sales once a month or over holiday periods or offer free shipping. Go to www.etsyonsale.com

Facebook and tweet about upcoming sales to prepare your audience, but DONT CONVO THEM. That is considered spam.
Hope these tips help boost your sales.
