How to be listed with competitors for variants of a product
I am facing a shopping-feed-problem I cannot solve:
The thing is that there are products that come in variations:
My shop (shopping feed) manages to get us listed for the main product. But once you use the dropdown (see example) to choose a size we do not appear any more. How can I be one of the shops listed for variants? Do I have to specify the size in my feed. Or is it the EAN or GTIN?
There is another thing, too: My Variants do have all the exact same name. The only thing that changes in my shop, when a customer picks a certain variant, is the price, the picture and the url-parameter: example
Does anyone know what to do?
Thanks in advance
