Welcome Joan!
I do not know anything about promote listings either... I was thinking about looking into it in a few months if other ways don't work.
Also follow what Joy says...what you put in your title, reading the handbooks, and making sure you are tagging the right words so people will search for you item.
What I have learned thus far is to be active within etsy. Follow people, favorite their shops, like their items...this way they may like and follow you back which creates a networking tree and get's your name out there.
Also expand your business to other social media (instagram, pinterest, facebook) that way you are reaching many other people around the world and not just people who look on Etsy.
I know it can be very overwhelming, but take one step at a time. For instance right now I have Instagram and Pinterests and this week I just started working on a facebook page. It takes time, but just be patient but active and things will change!
