Assets and asset groups

Performance Max campaigns have some unique characteristics regarding assets.

  1. There are a minimum required number of advertiser-provided assets of different types.
  2. Assets are grouped together in a collection called an AssetGroup, which is unique to Performance Max campaigns.
  3. Some Assets are generated automatically by Google using machine learning.

An asset group is a collection of assets centered on a theme or related to a target audience. The asset group is used to assemble all of your ads and build an inventory for all applicable ad formats for your advertising objective. Learn more about asset groups.

Asset groups contain one or more final URLs. At least one final URL is required. Use the URL that is most relevant to the conversion path for the given asset group and campaign objectives.


An AssetGroup is linked to an Asset by creating a new AssetGroupAsset and providing the following:

  • Resource name of the AssetGroup
  • Resource name of the Asset
  • AssetFieldType of the Asset in the AssetGroup


An AssetGroupSignal is a signal that you can provide to Google to optimize ad serving at the asset group level. There are two types of hints that you can provide to Google:

  • audience: A reusable collection of focused segments, demographic targeting, and exclusions
  • search_theme: Information about what your customers are searching for and which topics lead to conversions for your business that you can provide to Google AI

Only some ValueTrack parameters are supported for Performance Max campaigns.
