Yes, however, you must choose one or the other bidding type - Polyvore categories or product groups. If you choose to participate in product groups, you will need to assign products to groups through the “cpc_labels” field in your product feed. Products that are not assigned a label will be put into a “default” group. Once you are live on product groups, you cannot switch back to Polyvore categories. You can have a max of 200 product groups. Please contact the CPC Support Team if you would like to migrate to product groups.
