Let me first start with what are Custom Categories within eBay Shops.
Custom Categories are like departments within your shop that make it easier for buyers to find what they are looking for. You can now create up to 300 categories upto 3 levels in your shop.
Depending on the items, some sellers use product-based categories like- ceramics, glassware, posters while others use more flexible categories like sale items, seasonal, best-sellers, etc.
We recently expanded the Shops category navigation to
300 custom categories with up to three levels of categories and sub-categories.
This is a great feature to help you manage your shop and make it more buyer friendly.
