i've only opened up shop in january so i'm still fairly new as well, but in the past couple of weeks, i've had 3 new legitimate sales so it's starting to pick up!
what i noticed:
-using up all your tags REALLY helps because buyers will most likely see your items while searching, and items will show up depending on whether or not the buyer's search keywords match your tags.
-renew or list new items as often as possible. so space out your listings. let's say 1 or 2 new listings a day. that way your items will come up first or at least on the front page when a buyer does a search.
-the title of each item needs to be very clear. i mean, the title needs to describe exactly what the item is. for example, HAIR CLIP-Sultry Rosalie Pink. i precede the "cute" name of my item with what the item actually is.
-pictures do need to be of good quality. i'm currently working on redoing all my product pictures as well because the background is too cluttered and i want the item to be the main focus.
-set up a twitter account for your business, a facebook page for your business and even a blog! update onto those social networks every time you list a new item.
that's about all the advice i can give so far! hope this helps somewhat :)
