With this release, eBay continues its march towards a more Amazon-like experience in terms of helping buyers more easily find and purchase products. With structured data, eBay listings can be more easily indexed by search engines, including eBay's own search engine or external search engines such as Google. And if products are easier to find, the sales will follow as well!
Prior to this current push, eBay's listings were hard for search engines to find.
The interesting change with this update is that eBay will now allow sellers to use other product identifiers, and specifically Amazon ASINs. This new capability will be available in February, 2017.
And the even better news for CommerceESB users is that we continue to make it easy to include structured data as part of your eBay listings. See our article on structured data best practices to review what should be done and how.
At CommerceESB, we have a long track record of helping sellers create effective listings. Please contact your account manager if you want some advice -- we are happy to help our customers continue growing their business!
