The extent of customisation in your eBay listing template depends on the specific template package you choose. Generally, some of the elements you can customise include headers and footers, hero banners, tabs, popups, cross-selling items, and unique selling points (USPs). These features allow you to create a template that not only reflects your brand's unique style but also enhances the shopping experience for your customers, making your listings stand out in eBay's search results.
