I always send a link for all my new listings to my Facebook and Twitter accounts. I am the captain of a great team "Forget Me Nots Daily Discoveries" join some teams but be selective. Our team is like family, we help, critique and participate in everyone else's shops. It's a great way to spread the word on your shop.
Good luck, stay patient, that is key here, it doesn't happen overnight but as long as you persevere and continue making tweeks and improvements to your shop the customers will come.
