Google has updated its Performance Max campaigns to allow automatic use of sourced videos from approved sources. This change no longer requires advertisers to opt-in manually.
Previously, the use of sourced videos was an opt-in feature, turned off by default.
Now, advertisers must actively choose to opt-out if they do not want videos to be automatically sourced.
To manage sourced videos, advertisers can go to the Asset optimization section, where they can disable this feature or manage the sources from which Google can pull videos, such as URLs from their YouTube channel.
