Create a product group to organize your product inventory in Google Merchant Center. You can create product groups in a Shopping campaign using attributes derived from your product data, available within Google Ads. Then you can bid on these product groups.
Features of product group in Shopping campaigns
|Shopping campaigns use product groups to determine which items from your Merchant Center account appear on a search results page in a Shopping ad.|
|When you create a new Shopping campaign, a product group for “All products” is created by default, using the default maximum cost-per-click bid (max. CPC) you set during ad group creation.|
|You can run your Shopping campaign using just the “All products” product group, or subdivide it into as many product groups as you want by using product attributes like category, product type, brand, condition, item ID, and custom labels. You can also remove product groups as needed.|
|Each product can appear in only one biddable product group per ad group. You can also exclude a product from appearing in a product group entirely by using inventory filters.|
|Set and revise bids for each product group as often as you need, or exclude a product group from your campaign.|
|For Smart Shopping campaigns, reporting metrics can be different for the Product Groups tab when compared to the Campaign, Ad Group, or Ads tabs. This is because the Product Groups tab can only report on product level data.
