Hey there everyone! I just have a quick question that I'm getting different answers to no matter where I look and I'm hoping to get some clarity. I was on the phone with an eBay representative the other day and she was going over something in a listing I have and noticed my UPC field was blank. She mentioned that I should fill it in "Does not apply." I did so and it now seems I've had a steep slow down in views and general action on my listings. Prior to this, I had always left it blank. I'm curious as to what everyone else is doing? and how effective it is for their business. I'm relatively new to this so any help would be much appreciated! Looking forward to hearing back!
