eBay.com drops duplicate listings policy

eBay.com announced yesterday that search results would no longer hide duplicate listings from the same seller, a process that’s become known as “de-duping“. Where an individual seller has more than one identical listing for sale, all instances will now show in search; previously, only one would have been displayed. eBay say that sellers are now taking advantage of the boost that recent sales give their listings, by combining identical items into single listings offering multiple items for sale, and that “this has proven to be the right strategy for sellers and a great shopping experience for buyers”.

But this doesn’t feel quite like the whole story to me. If the policy works, and sellers are changing their behaviour as desired because of it, why change the policy? The duplicate listings policy was – at least in part – intended to stop a few huge sellers dominating particular categories: might we assume that eBay are now happy to have one or two or their largest sellers dominant after all?

eBay.com will continue to show a maximum of ten listings per seller per search results page. Sellers should at least spread their listings out over time rather than listing in ‘clumps’ to try to avoid having them hidden under this policy.
