Here are some tips and suggestions.

  1. Look at your products in their categories and if ALL products from that category can be listed in one category on Trade Me, then you can map them all from the 'Category Mapping' page. From the dashboard, click 'Map Now' then toggle to the Category page by clicking 'Categories' from the top right.
    See - FAQ on how to map by category.

  2. If your products are not in categories similar to Trade Me, then you will need to map products individually from the Product Mapping page.
    From the dashboard, click 'Map Now'. This page has all of your products that need mapping. You can search and filter your products to make it easier to map multiple products at once.

  3. If the suggested categories are not appropriate for your products then you can choose categories.
    We have made it easier to choose categories by providing you with the most recent categories you have mapped to.
    See - FAQ on how to select your own categories for mapping

Relevant points to note:

Any newly imported products in Trade Runner that are part of a Category to Category or Product to Product mapping rule will continue map to that Trade Me Category by default.   If you do not want new products to fall into your existing mapping rules then you can delete the mapping rule from both the Product and Categories page.

This applies when doing Product Mapping and Category Mapping.  If you select one of the Trade Runner suggested Categories this will 'Create a mapping rule' which Trade Runner will continue to use when uploading products to Trade Me.
