Hi Black Friday Sales,
You will not be able to select eBay store categories when posting your listings since you don't have an eBay store, however, there are categories that show up in your Auctiva store which your buyers can reach by clicking the link in the bottom-right of your scrolling gallery. The categories that will show up in your Auctiva store by default are the primary eBay categories in which your items are listed.
If you would like to create custom categories for your Auctiva store, you can do so by clicking the "Search Categories" link under the "Store" tab within your account.
For a listing to appear in a given custom search category, the keyword(s) specified for that search must appear in the title of the listing. If you set your Match Logic to “All Words”, the search results will only return listings with titles containing all of your keywords. If you set it to “Any Words”, the search results will return listings with titles containing any one of your keywords.
If you have any additional questions or concerns, please feel free to contact our customer support team using the web form on the following page of our site:
