The Shopping Product Group Refresher Pro detects the structure in which ad groups and product groups were created, and it finds all the new products that are in the feed but which don't have product groups or ad groups in the campaign. It then creates new ad groups/product groups for them. 

In order for the tool to create new items, a consistent structure and certain basic parameters must be met, otherwise, you'll see a warning message. Here you'll find what each message means and how to resolve it. 

Shell Ad Group

This warning message can be due to one of the following reasons:

  • This ad group has no product groups.

  • This ad group has no product groups other than 'All Products'.

  • This ad group only contains one product group (“All Products”).

Split out EE Node

This warning message means the system can't process that particular ad group, as there are split out Everything Else nodes.

Invalid Hierarchy

This warning message can be due to one of the following reasons:

  • This ad group is targeting all the items in the feed. When using a multiple ad group structure, the 'Everything Else' product group at the highest level should be excluded.

  • There are missing levels in this ad group.

  • There should be just 1 other child at every level, where the 'Everything Else' node is excluded.

  • The cluster has conflicting split-level and split-depth values. The system could not reach a conclusive split structure.

Multiple Hierarchies

There seems to be no conclusive cluster hierarchy with more than 75% coverage. 

It is recommended to follow a single structure for Shopping Product Group Refresher to work. Please get in touch with our support team if you need assistance or for best practices.

All the ad groups in this cluster have issues. We could not generate new ad group suggestions for this cluster.

You are using a potentially incorrect campaign filter -> Custom Attribute 0: XYZ. The Custom Attribute 0 value ‘XYZ’ is not present in your Merchant Feed.
