I am not sure this helps, but I have started to put the link to my shops sections in my listings. Like vintage kitchenwares, or collectible glass. Most people will search for a certain item like for example Pyrex mixing bowls. When they go to your listing most people just go to that listing and if it isn't what they want they just go search again. If you have a shop section you can put that link in each listing and they can click on it and see the other things you have for sale in that same section. I don't know if it helps, but I have noticed since I started that I have gotten more views on things that were not getting seen. Maybe that will lead to more sales?
