You ran a successful awareness campaign with a video ad that's 30 seconds long, and you now see the value in remarketing to audiences who saw it with memorable, shorter video ads. What video ad format should you use to achieve that goal?

Bumper ads are short, non-skippable video ads designed to deliver a memorable message quickly. They work well after a longer awareness ad because they can reinforce the original message with brief follow-up creative. This format is useful for remarketing when the goal is recall and repeated exposure without needing another long video. In Google video campaigns, bumper ads are commonly used for efficient awareness reinforcement.
