Times have changed on eBay. Its expectations of sellers is greater. Gone are the days where all you needed was a good picture and adequate title to make a sale. I looked at all four of your listings and had some thoughts.
Consider adding more photographs of the items, from all angles and vantage points. Use a light colored background. White is most preferred for inclusion on Search engine results.
It is said that high traffic on a listing without sales can begin dropping it lower in Search. In your case, you have the traffic but zero sales conversions. The buyer clicks through, but then abandons the listing. Why?
I noticed the listings are just bare bones. There is minimal detail in Item specifics. There are virtually no descriptions, but only a repeat of the title. Keywords in the title, IS and descriptions are used to determine Search placement in results, and not just on eBay, but thru Google, Bing and the like. It is hard to compete with a seller who does have a complete description over one who does not.
To compete on todays eBay, listing information is vital. Below is a link on how to improve one’s sales conversions that i thought might be helpful. Good luck, and hope your sales improve.
