developing a consistent brand will help. one way to do this is to have a coherent "look" to your photos. right now, i wouldn't be able to tell that your photos are from your shop- they don't have a cohesive look. you could try photographing your items in the same location, or with a similar prop, so that people can easily identify your shop when they see your item listings. eventually, your shop will develop a reputation, and being able to identify your listings by a quick look will encourage viewers who like your shop to click on your stuff.
