Create a companion banner for a video ad

Hero image of the YouTube Companion Banner

A companion banner appears next to your video ad on YouTube. You can either upload a custom image for the banner, or allow Google Ads to generate an image from your YouTube channel banner. In this article, you'll learn how to create a companion banner in Google Ads.

Things to know

  • Skippable in-stream ads, non-skippable in-stream ads, and bumper ads support companion banners.
  • Companion banners only show on desktop. They don't appear on mobile devices, connected TVs, or other devices that support YouTube.
  • Companion banners appear next to the ad on the YouTube watch page. When a viewer clicks on the companion banner, they'll go to a website URL that you provided when creating the campaign.
  • A click on companion banner counts as a view (even if the viewer doesn't watch at least 30 seconds of the ad).
