I learned from another Etsy shop owner something that I guess is obvious to most but wasn't to me is that renewing an item will bring in new views to the item by people who are searching under what is recent and new to Etsy. So she recommended that you add something new to the shop everyday and if not at least renew an item. Then cost of course is an extra 20 cents to do so, so I like have a goal of actually posting something new.
Also good pictures has made all the difference for my shop. I am not a photographer, but I met a lady across the street that is. And we now barter, her for photography for a few crocheted baby props. And we also advertise for each other. So I highly recommend bartering and teaming up with another small business owner, think about your product and see if there is some one in the area that could do something to compliment what you do. One other person I have thought to team up with is a lady who sells handmade soap locally and I have thought about selling the cotton crochet washcloths and bath puffs, so I have considered seeing if she wanted to team up on some gift baskets we could both sell, not ask yet but its an idea. So those are some examples, next time you are at a craft fair look around and see who you might could help and could also help you.
