Listing templates are especially useful when you’re selling items of the same category but with different unique designs or specifications. You no longer have to start from scratch every time you list a new item. It also helps ensure that you give buyers consistent and accurate information across all your listings.
Here’s an example:
Let’s say you have 20 new t-shirts with different designs. They all fall under the same item category. Furthermore, sizes, prices, returns & shipping policies are the same across the board.
So, what you do is create a T-Shirt listing template with the information that will repeat for all your t-shirt listings. Then focus on updating the photos, unique descriptions and specifics for all 20 T-shirts.
Once you have set up a template, it's easy to revise, rename, or delete it, if you need to make a change.
However, remember to stay on the safe side of the duplicate listings policy.
