Related video extensions are now globally available to all advertisers who use Google Ads. With related video extensions, you can show a list of 2 to 5 related videos below your video ad on the YouTube mobile app.
Related video extensions extend your message beyond your primary video ad, keeping viewers engaged with your creatives (including other videos on your YouTube channel).
