All inventory items\nin a product group have the same bid.\n\nAd groups within a Shopping campaign can have up to 20,000 product groups.\n| **Key Term:** In the Google Ads API, a product group is referred to as a [Listing\n| Group](/google-ads/api/docs/shopping-ads/create-listing-groups).\n\nManual steps\n------------\n\nHere are the steps to create product groups through the Google Ads UI.\n\n1. [Create a new Shopping campaign](https://support.google.com/google-ads/answer/3455481) for **All Products**.\n2. Create a new ad group.\n3. Click **+** next to **All products** to add a subdivision.\n\n Products groups can be subdivided up to 6 times.\n4. Use the following steps to manually add subdivision values as a list:\n\n 1. Select **Bulk add values manually**.\n 2. Add each subdivision (one item per line).\n 3. Confirm the changes.\n\n This is only available for some attributes.\n5. Set a max CPC bid for each product group. If you use an automated bidding\n strategy, max CPC can be set for you.\n\nFor more detail, see [Manage a Shopping campaign with product groups](https://support.google.com/google-ads/answer/6275317).\n\nAutomatic steps\n---------------\n\nMake sure you have already completed the following:\n\n1. [Link Merchant Center to Google Ads](/google-ads/shopping/full-automation/articles/t15).\n2. Create a new [Shopping campaign](/google-ads/shopping/full-automation/articles/t18).\n3. Create a new [ad group](/google-ads/shopping/full-automation/articles/t19).\n Here are the steps to create a [Listing Group](/google-ads/api/docs/shopping-ads/create-listing-groups) through the Google Ads API:\n\n4. Use the following steps to create a root node for the [listing group](/google-ads/api/docs/shopping-ads/create-listing-groups) tree:\n\n 1. [Create a new listing group](/google-ads/api/docs/shopping-ads/create-listing-groups#listing_dimensions).\n 2. Set the ID of the root to a [temporary value](/google-ads/api/docs/shopping-ads/create-listing-groups#temporary_ids), for example `-1`.\n\n Each subdivision must be completely partitioned when you create\n a listing group tree.\n\n The tree must have a grouping for **other** (**Everything else** in the\n Google Ads UI). Mutate operations won't work if you don't do this\n correctly.\n5. Use the following steps to create a child node:\n\n 1. Create a new listing group and set the `ListingGroupType` to one of the following:\n - `UNIT`. This is a leaf node of the tree. Doesn't need to be biddable. You can't bid per unit in Smart Shopping campaigns.\n - `SUBDIVISION`. This splits the tree by another subdivision. Remember to set a temporary ID for the node.\n 2. Set the `case_value` of the node to the [`ListingDimensionInfo`](/google-ads/api/reference/rpc/latest/ListingDimensionInfo) you\n want to subdivide by (**product attribute** in the Google Ads\n UI), for example `product_brand`.\n\n To partition a product group by [`ProductBiddingCategory`](/google-ads/api/reference/rpc/latest/ProductBiddingCategoryInfo), set the\n value to a numeric ID, not the category string. You can find the ID in\n [`ProductBiddingCategoryConstant`](/google-ads/api/reference/rpc/latest/ProductBiddingCategoryConstant#id).\n 3. Set the parent ID for the node to the `getId` value of the\n parent subdivision or root node.\n\n A listing group tree can be no more than seven levels deep.\n6. Repeat step five for every `UNIT` of the subdivision at the current\n tree level.\n\n Include a leaf node with an empty `case_value` for each subdivision. This\n represents all other values.\n7. For each `SUBDIVISION` at the current level:\n\n 1. Take note of the ID value. This is the parent ID for the next level.\n 2. Follow the tree down a level.\n 3. Repeat steps five to seven.\n8. Create an [`AdGroupCriterion`](/google-ads/api/reference/rpc/latest/AdGroupCriterion) for every `UNIT`. This associates the listing\n group with the ad group.\n\n Other ad groups and campaigns with lower priority may still bid on\n products that fit the same criteria. Apply [`negative`](/google-ads/api/reference/rpc/latest/AdGroupCriterion#negative) to exclude a\n product group from bidding.\n9. Enable the ad group to start bidding with the listing group structure.\n\nSee [Create a new listing group](/google-ads/api/docs/shopping-ads/create-listing-groups#listing_dimensions) and the [python example](https://github.com/googleads/google-ads-python/blob/master/examples/shopping_ads/add_shopping_product_listing_group_tree.py)\nfor more detail.\n\nHere's an example of a listing group tree:"]]
