YouTube In-Stream vs Shorts vs Bumper for Direct Response

Eduardo Monteiro · 2026-10-07

Duration and structure by format

1. In-Stream: Ads that appear before, during, or after long-form videos. They can vary in length, usually between 15 to 30 seconds. The structure should be direct, with the main message in the first 5 seconds and a clear call to action at the end.

1. Shorts: Short vertical videos up to 60 seconds long. The structure should make an impact from the start. Use dynamic visual elements and quick messaging. The goal is to grab attention fast.

1. Bumper: 6-second ads that appear before videos. They should be extremely concise and focus on a single message. A clear, visual call to action is essential.

Targeting by intent

• In-Stream: Ideal for broader targeting using interests and behaviors. A good option for remarketing, reaching users who have already shown interest.

• Shorts: Geared toward younger, more engaged audiences. Use targeting based on specific interests and recent behaviors. Shorts are consumed quickly, so keep your messaging direct and fast-paced.

• Bumper: Best for brand reinforcement. Targeting should be based on broad interests, since the goal is to increase brand recall. Use it to complement larger campaigns.

Content exclusions

• In-Stream: Exclude video categories that aren’t related to your product or service. This keeps your ad from showing up in unsuitable contexts.

• Shorts: Exclude content that could be considered sensitive or that doesn’t align with your brand image. This is crucial for maintaining a good reputation.

• Bumper: Exclude channels that aren’t relevant to your target audience and could result in low relevance. This helps ensure your ad always appears in a favorable context.

View rate metrics

• In-Stream: Ideally, aim for a view rate above 20%. If it’s below that, review your content and targeting.

• Shorts: The view rate tends to be higher because of the fast-paced nature of the format. Aim for a view rate around 40% or higher.

• Bumper: Here, a 30% view rate is considered good. Focusing on content that grabs attention quickly is essential for success.

When to use each one

• In-Stream: Use it when you have a longer message and need to explain a product or service in more detail. Ideal for campaigns that require more context.

• Shorts: Use it when the goal is to drive quick engagement and grab the attention of a younger audience. Great for launches or quick promotions.

• Bumper: Use it to reinforce branding campaigns or drive brand recall. Ideal as a complement to other, larger campaigns.
