I'm in the process of hopefully making it easier to shop for matching, or similar items in my shop. I picked up the tip from muyinmolly, through the Full Time Etsy Crafters Blog. I'm adding links to shop search results, instead of to a specific listing, or shop section. For example, in my red bridal bouquet listing, I added a link to the search results for the terms "red wedding."
There are a lot of other great tips in that article, from full-time sellers that have reached major "milestone" sales numbers. The article can be found here.
