I sell some very niche widgets and I am having trouble getting listed on Google Merchant Center. I have a competitor who has his products listed so I know they must be putting something in the MPN or UPC field. Is there any way by looking at their products pages on google shopping that I can figure out what that value might be?
These arent hand crafted products so I don't believe they will qualify for an exemption either...
Any ideas would be great!
