Bumper Ads

By the AdFlint research team · Last reviewed November 2026

Non-skippable YouTube video ads of five to six seconds, sold on impressions, designed to land a single message before the content plays.

The length is short and unskippable, so the unit works as a frequency and recall builder rather than a way to explain anything. It is often paired with a longer skippable ad in the same campaign to reinforce it. The mistake is cutting a thirty-second commercial down to six seconds; the format needs one idea, written for six seconds from the beginning.

Key takeaways

  • Bumper ads are non-skippable video ads of 5 to 6 seconds, bought on Target CPM.
  • They serve on YouTube, YouTube Playables, and Google video partners through Video reach campaigns, Reservations, and App campaigns for installs.
  • They suit reach, recall, and repeating a message, not explaining an offer or driving direct response.
  • Write the idea for six seconds from the start instead of trimming a longer ad.

In practice.

Bumper ads are the shortest video ad on YouTube. Google's format overview says they are non-skippable video ads lasting between 5 and 6 seconds, and they can play before, during, or after another video. They serve on YouTube videos, on YouTube Playables in the mobile app, and on Google video partners. Google lists the campaign types that support them as Video reach campaigns, Reservations, and App campaigns for installs. They are classed as in-stream, they can be remarketed to, and they cannot count toward TrueView views. Bumper ads can also be bought through Reservations and as part of App campaigns for installs, as well as Video reach campaigns. Which one you use depends on whether you want auction pricing or a booked, guaranteed delivery.

Billing is by impression. Google says bumper ads use Target CPM, so you pay for every thousand times the ad is shown, not for views or clicks. The viewer cannot skip, so the full message is delivered. That makes bumpers a reach and frequency tool. You set a target CPM, a budget, and an audience, and the system tries to show the ad to as many unique people as it can. Reach is the metric to judge it by, along with measures like ad recall if you run a brand lift study. Because the format is classed as in-stream and can be remarketed to, you can build a list of people who watched your other videos and show them a short reminder. That sequencing is where bumpers earn their place.

Bumpers work best as a partner to a longer ad. A common pattern is a skippable in-stream ad that explains an offer, followed by bumpers that repeat one idea to people who have already seen it. Because bumpers are remarketable, you can aim them at people who watched your other videos. They are a poor fit for direct response. There is no room for a call to action to do real work, there is no click-driven cost model, and you cannot test a long pitch in six seconds. Good bumper creative is built backward from one line. Decide the sentence first, then shoot or animate only what supports it. Show the product in the first second, and put the name on screen from the start.

The usual mistake is cutting a 30-second commercial down to six seconds. Chopped-up TV rarely survives; the format needs one idea, planned for 5 to 6 seconds from the start: one product, one benefit, the brand name early and clearly, and legible on a phone with sound off. Another mistake is buying bumpers with no frequency plan, so the same people see the ad dozens of times. A third is judging them on conversions in the same report as skippable direct-response campaigns. Keep an eye on frequency. Because the ad cannot be skipped, showing it too often to the same person wears out its welcome quickly. A frequency cap in reach campaigns spreads the same budget over more people.

To read results, look at impressions, unique reach, average frequency, and cost per thousand impressions, and compare them between the bumper and your other formats. This week, write the single sentence the ad must land, check that it can be said in 5 seconds out loud, and storyboard three frames. Pair the bumper with a longer asset in the same account so you can tell later whether people exposed to both took more action than people who only saw one. Compare the bumper's cost per thousand impressions with other formats to make sure the reach is priced sensibly, but remember that the goal is exposure and recall, not clicks.

Worked example

A bakery repeats one idea to a local audience

Suppose a bakery wants more people in its city to know about its Saturday cinnamon rolls. It sets aside $4,000 for a bumper campaign. If the target CPM works out to $8 (a made-up figure for this scenario), the budget buys about 500,000 impressions, since 4,000 divided by 8 times 1,000 is 500,000.

If those impressions reach roughly 200,000 different people, the average frequency is 2.5. The ad has one line: rolls, hot, Saturday morning. The bakery does not count clicks, because bumpers are not built for them. It compares Saturday foot traffic and brand searches during the flight with the previous month. If the bakery had wanted to explain a catering offer, it would have used a skippable ad that could run longer. To check it worked, the bakery also asks new customers how they heard about it, which gives a rough read that a click report cannot.

Bumper Ads compared with

The settings this gets confused with, and how to tell them apart.

Common questions.

How long are YouTube bumper ads?

Google's format overview says bumper ads are non-skippable video ads lasting between 5 and 6 seconds.

How are bumper ads billed?

They use Target CPM, so you pay per thousand impressions rather than per view or click.

Can people skip a bumper ad?

No. Bumper ads are non-skippable, so the full 5 to 6 seconds plays.

Are bumper ads good for lead generation?

Usually not on their own. They are built for reach and message repetition. Direct response is better served by skippable in-stream ads or Demand Gen campaigns with a conversion goal.
