hi Sibel!
You are in very good company. There are more stores without sales than people are aware of.
First off, how many organic views do you have? Is the problem that your items are not seen? Or do people see your things and move away without buying?
Looking at a few of your things I had the impression that you could draw in more views by working on your keywords and titles. For instance, IPad cases are also called iPad sleeves. Sometimes people refer to their iPad cozy. Using more keywords could help you being seen more.
