What is a eBay defect? A ‘defect’ is a transaction that’s considered to create a bad shopping experience for buyers. We understand that not all transactions go well, and this is just a part of doing business. Still, these transactions can seriously affect a buyer’s likelihood to buy with you again. With the new performance measurement, we’ll be better able to reward sellers that provide excellent customer experience. The new measurement will also improve our ability to identify experiences that may drive buyers away.
