Set up an adaptive shopping campaign
Best practices for adaptive shopping campaigns
Create a basic structure Search Ads 360 can fill in
Start by creating a basic structure that Search Ads 360 can fill in with details. That is, organize your ad groups and product groups in a way that reflects your management and reporting needs, and remember that some of the nodes within your product group trees will become populated with additional child nodes as Search Ads 360 creates new product groups.
Multiple ad groups
If your campaign includes more than 10,000 products, 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 products.
