Hi Mugen!
The title and tags are important, but you have to get your items in front of folks. I just learned this recently and my sales peaked! I set up a pinterest, facebook and twitter account. I visit blogs daily leaving indepth comments that have nothing to do with my shop, with a link back to my blog, which showcases an etsy mini shop. I joined teams and participated in their games....Also, I have about 400 items in m shop which has helped, too.
