Step 4 of 6: Set up your asset groups and assets (optional)

The campaign will use the marketplace product feed to serve ads. Additional assets aren’t required, but you may provide it to help enhance the performance, reach, or inventories of your ads.

Listing groups are required and will default to all products in the specified marketplace account.

1. On the “Asset group” page, enter a unique asset group name.
2. Confirm Listing groups for the campaign. Listing groups allow you to select which products will show in your Performance Max campaigns' ads. The default will be all products in your attached marketplace account, but if you wish to only use a selection of products follow the steps below:
   1. Click the pencil icon next to "All products".
   2. Select Use a selection of products in your ads.
   3. You can select products by Category, Brand, Item ID, Condition, Product type, Channel or Custom labels from the dropdown. You can also choose values in bulk by manually entering product types separated by line breaks.
   4. Check products that you want to include in your Performance Max ads and they'll appear in the column to the right. To remove products, click the next to the product group.
   5. Click Save to finish setting up your Performance Max campaign.
3. Build your asset group using the guidelines below.
