Product groups in Google Ads are a subset of an advertiser’s inventory of products. As the name suggests, a product group is a group of products. In shopping campaigns, ad groups consist of product groups which are equivalent to keywords in search campaigns. And, all the products in a product group use the same bid.
In this article, I have explained how to subdivide product groups, editing and removing the existing ones.

How do Product Groups in Google Ads work?
When you create your first shopping campaign, you see that there is one ad group with a product group called “All Products“. This product group includes the complete inventory of your products.
The best practice is that you divide your product stock into smaller groups with various subdivisions. This division allows you to collect performance data and use that information to bid more precisely on products.
How do subdivide product groups for strategic bidding?
Google Ads allows seven levels of subdivision for every product group. The order of this division is solely your choice. The easiest method is to have all your products in a single product group and bid the same for all the products. However, it isn’t the best of practices.
Organizing your products by clubbing them into smaller product groups sorted by their brand or Google product category is a must if you want to monitor the performance of individual products. Every shopping campaign ad group can host up to 20,000 product groups.
Note: Setting bids on subdivided product groups is not possible.
How to subdivide Product Groups in Google Ads?
You can determine product groups using attributes from the product data feed in your Google Merchant Center. There are eight different attributes to choose from:
- Item ID: Item ID is the identifier (id) for your products. Each product has a unique id.
- Brand: Brand is the name of the manufacturer of your products.
- Category: The category of products is based on the taxonomy of products defined by Google.An example of a category string following Google product taxonomy: Animals & Pet Supplies > Pet Supplies > Bird Supplies > Bird Cage Accessories > Bird Cage Food & Water Dishes
In merchant center product data, the “>” characters illustrate the hierarchical levels in the product category. If you do not assign the class to a product, Google might specify a category for your products automatically.
Note: Product group subdivision by category is available only for advertisers targeting Australia, Brazil, France, Germany, Italy, Japan, Norway, Sweden, the USA, the UK, the Netherlands, and Turkey.
- Product type: Product type is a user-defined category of products.An example of a product type string defined by the user: Home & Garden > Kitchen & Dining > Kitchen Appliances > Deep Freezer.
- Custom labels: Google permits you to create up to five custom labels for your products. You can use custom labels to mark your products based on their availability, etc.
Examples of custom labels: Out of stock, in stock, sale, discount, seasonal, etc. - Condition: The condition attribute defines the status/state of products in your inventory. The condition of a product can be new, used, or refurbished.
- Channel: Channels are where you sell your products, i.e., in (local) physical stores or (online) via e-commerce stores.
Note: Changes that you make to product attributes in your product feed won’t be reflected in product groups automatically. You have to update product groups manually.
