An asset group is a collection of creatives centered on a theme or related to a target audience in a Performance Max campaign. The creatives of your asset group are used to assemble all of your ads and build an inventory for all applicable ad formats for your advertising objective.
An asset provided in an asset group can be combined with any other asset from the same group to create ads that serve across Google Search, Google Maps, Display, YouTube, Gmail, Discover feed, and Google partner websites. You may create multiple asset groups per campaign to group assets by theme or to group assets with different targeting.
Group asset groups by similar themes and audiences
Many advertisers find it helpful to base their asset groups on the sections, categories, or themes that appear on their website.
It’s recommended to base your asset groups on the sections or categories of the products that appear on your website.

Video specifications
|
Videos longer than 10 seconds are required for all Performance Max Campaigns If you do not upload a video, one may be generated for you from other creative
|
If you don’t add a video to your Performance Max asset group, then one or more videos may be auto-generated from the assets in your asset group. Auto-generated videos may be auto-generated in longer, standard YouTube form or in a vertical format so that they may serve on YouTube Shorts. If you don’t have a video asset and don’t want to use the auto-generated videos, you can use the Google Ads video creation tool to create a video for use in your Performance Max campaign. Advertisers may also upload a YouTube Shorts-eligible video (vertical format, less than 10 - 60 seconds in length), which may be eligible to serve on YouTube Shorts. To learn how to create videos in Google Ads, visit Create a video using Asset library.
Google may automatically resize your video ads to increase your performance by platform and improve ad strength. After you’ve created and uploaded your creative assets, landscape videos may be scaled to square (1:1) or portrait (9:16) aspect ratios for YouTube Instream and YouTube shorts. Google will review each video to ensure that quality isn’t lost, however if you have an issue with the resizing please contact Google support to help you opt out of this service.
