You will want to set up your templates in a way that will allow you to effectively list products with your desired categories, shipping settings, return settings and any design elements you wish. Once a template has been created you will be able to attach products to them, any products attached to a template will have all the template settings applied to the product listings on eBay. The template can be modified after it has been created, any modifications done to the template will be pushed out to any products/listings associated with it.
Things to consider regarding templates:
- eBay Categories
- eBay Store Categories
- Shipping Options (Free Shipping, International etc.)
- Return Policies (can vary by eBay category)
- Brand Specific Templates
