Product groups that Search Ads 360 can subdivide

Search Ads 360 can automatically subdivide any product group by the product ID attribute, with a couple of exceptions:

• The product group already points to a specific product ID, or one of its ancestors points to a specific product ID.
  If a product group already contains products with a single, specific product ID, Search Ads 360 cannot further subdivide it or any of its children.

• The product group's “Everything else” child is excluded.
  Products in an excluded "Everything Else" group cannot receive traffic, so there are no eligible products to divide.

Search Ads 360 stops subdividing product groups once the ad group contains 2,000 product groups. If your campaign includes more than 10,000 product IDs, consider creating multiple ad groups in the campaign and set up each ad group so that its product groups include no more than 10,000 product IDs.

Search Ads 360 can subdivide a product group by the product ID attribute if the group contains more than one product. 

Example

Here's an example product-group tree along with an explanation of which product groups may be automatically subdivided by Search Ads 360:

Product groups	Subdivided by	Can be auto-subdivided by Search Ads 360?
All products	Product type level 1	No: it's subdivided by Product type level 1
- Electronics	Category level 1	No: it's subdivided by Category level 1
◦ Cameras	Product ID	Yes.
■ abc-def-123	No subdivision	No: it contains a single Product ID
■ abc-ghi-455	Channel	No: it contains a single Product ID
• Online	No subdivision	No: its parent contains a single Product ID
• Local	No subdivision	No: its parent contains a single Product ID
• Everything else in 'abc-ghi-455'	No subdivision	No: its parent contains a single Product ID
■ Everything else in 'Cameras'	No subdivision	Yes, as long as the group isn't used to exclude products. New subdivisions of this group appear as siblings of the Cameras group.
◦ Everything else in 'Electronics'	No subdivision	Yes, as long as the group isn't used to exclude products. New subdivisions of this group appear as children of the group. For example, Everything else in 'Electronics': abc-jkl-789.
