eBay now insist that sellers listing in certain categories match their product against the relevant eBay catalogue entry when there is one available.
Whilst you should be able to match your products to the eBay catalogue at the time of listing, there’s a pretty fair chance that you already had products listed on eBay which haven’t been linked to a catalogue entry. eBay have made a available to help you find matches for your live listings and quickly link them to the relevant catalogue entries.
It’s important to match your products in categories where use of catalogue is mandatory for two reasons. Firstly it ensures that your products can be found in search by buyers looking for your item – That’s the carrot, and the stick is that sellers who repeatedly list items without the catalogue or fail to relist with the catalogue when there is a product match, will be subject to a range of actions including listing removal, limits of buying and selling privileges, and possible account suspension.
Even if you think all of your products that need to be matched to a catalogue item already are, it’s worth running the every week or so to ensure that none have slipped through the net.
