Assets in a Performance Max Campaign

Performance Max campaigns have some unique characteristics regarding assets .

There are a minimum required number of assets of different types.
Assets are grouped together in a collection called an AssetGroup , which is unique to Performance Max campaigns.
Some assets can be generated automatically by machine learning.

Code example

The following code snippet illustrates creating the necessary repeated assets in a new request:

Automatically created assets

Google automation using machine learning generates additional assets as needed to cover all relevant channels. Assets are automatically mixed and matched based on which Google Ad channel (such as YouTube, Gmail, or Search) your ad is being served on.

Text assets

You can associate a page feed in your account with a Performance Max campaign to automatically generate assets .

To link a page feed with a campaign, use the same process as used for Dynamic Search Ads:

After you've associated a page feed, make sure the AssetAutomationSetting of type TEXT_ASSET_AUTOMATION is set to OPTED_IN . This is the default setting if you didn't set the AssetAutomationSetting when creating the campaign.

Using this setting means your campaign can use content from your landing page, domain, and provided assets to customize ads when predicted to improve performance. We recommend leaving this as OPTED-IN .

Video assets

If you don't add a video to your Performance Max asset group, then one or more video assets might be generated from the assets in your asset group. If you no longer want auto-generated videos to serve in your Performance Max campaign, then you can upload your own custom video, and the auto-generated videos will stop serving.

Smart automation may enhance your YouTube video assets by adjusting video orientation and intelligently shortening them to highlight key moments. If you prefer to maintain your original video assets, set the AssetAutomationSetting of type GENERATE_ENHANCED_YOUTUBE_VIDEOS to OPTED_OUT .
