YouTube Shorts Ads

By the AdFlint research team · Last reviewed November 2026

Vertical video ads that appear between clips in YouTube's short-form Shorts feed, swiped past like the surrounding organic content.

Shorts inventory is included in Video, Demand Gen, Performance Max, and App campaigns rather than bought on its own, and it serves 9:16 assets to a fast-scrolling, sound-on audience. It suits sharp hooks and creator-style production. The mistake is letting a repurposed horizontal ad be auto-cropped into the slot, where letterboxing and cut-off captions mark it instantly as recycled television.

Key takeaways

  • Shorts ads appear between organic Shorts and are skipped by swiping, served through Demand Gen, Video view, Video reach, Performance Max, App, and Reservations campaigns.
  • Under CPV a view counts at 10 seconds, a click on the call to action, or a like, comment, or share, and under Target CPM an impression counts when the ad starts playing.
  • They can be remarketed to.
  • Make vertical creative with the hook in the first second instead of cropping a horizontal ad.

In practice.

YouTube Shorts ads appear between organic Shorts in the vertical, swipe-through feed. Google's format overview says they show between organic videos and can be skipped by swiping, and that they appear across desktop, tablets, mobile, and connected devices. Google recommends a length under 60 seconds. They are not a separate campaign type. Google lists the campaigns that serve them as Demand Gen, Video view campaigns, Video reach campaigns, Performance Max, App campaigns for installs and engagement, and Reservations. Shorts ads run on desktop, tablets, mobile, and connected devices, but the swipe-through behavior is mostly a phone habit. Preview your creative on a phone before approving it, since text near the edges can be covered by interface elements.

Billing follows the bid strategy. Under CPV bidding, Google says a TrueView view counts when the viewer watches 10 seconds or to the end, or clicks the call to action, or likes, comments on, or shares the ad, with one charge per impression. Under Target CPM, an impression counts when the ad starts playing, and a viewable impression requires at least 50 percent of the ad on screen for two continuous seconds. Shorts ads can be remarketed to. Demand Gen lets you choose specific channels, such as Shorts only, if your creative suits it. Because Shorts can be a small part of a broad campaign, check how much of your budget went there. In Demand Gen, channel controls let you choose Shorts alone, and in other campaign types you may need reports by placement.

Where it fits: Shorts is an attention game. Viewers move fast and judge the first second. Creative that looks like a Short, a person talking to the camera, a quick demonstration, a sharp text hook, tends to fit the feed. Demand Gen accepts horizontal, square, and vertical videos, but a vertical asset made for the slot is the sensible choice. For a small business, Shorts works for product demos, before and after clips, and local service teasers, especially when paired with a clear offer in the description or call to action. Hooks matter more than polish. A person on camera, a surprising result, or a plain statement of the problem in the first second holds more attention than a branded intro.

The mistake is letting a repurposed horizontal ad get cropped or letterboxed into the slot, where cut-off captions and black bars mark it as recycled television. Other mistakes: opening with a logo animation, which loses viewers in the first second, and hiding the offer in the last five seconds. Also, running Shorts as part of a broad campaign without checking placement reports, then not knowing how much budget landed there. Some campaigns let you exclude or isolate Shorts; others do not. Because Shorts ads can be remarketed to, they work as a retargeting touch for people who watched your longer videos, and as a first touch that feeds an audience you can follow up elsewhere.

To read results, use the placement or channel breakdown where available, and compare view rate, cost per view, and conversion cost for Shorts against other surfaces. This week, make one video shot vertically with the hook in the first second and captions inside the safe area, then run it alone against your cropped horizontal version. Do not judge by impressions. A Shorts view that counts at 10 seconds is a different signal than a skipped in-stream impression, so compare against the same bid strategy. Compare Shorts results using the same bid strategy as other formats. A CPV view at 10 seconds and a Target CPM impression are different events, and mixing them gives a misleading comparison.

Worked example

Cropped versus native vertical

Suppose a plumbing company spends $900 on Shorts in a Demand Gen campaign with CPV bidding. Its first ad is a horizontal video cropped to fit. Out of 100,000 impressions, 6 percent become views, which is 6,000 views, so the cost per view is $0.15 (900 divided by 6,000).

It then shoots a vertical clip of a plumber opening a clogged drain, with a text hook in the first second. On a similar 100,000 impressions, 9 percent become views, which is 9,000, and cost per view falls to $0.10. The numbers are assumed for this scenario. The point is that fit with the feed changes the share of people who stay, and CPV pays for the ones who do. The company also moves the offer to the first three seconds on a third version, because the view count rose but calls still lagged.

Common questions.

Where do YouTube Shorts ads show?

Between organic videos in the Shorts feed, on desktop, tablets, mobile, and connected devices, per Google's format overview.

Can I run only Shorts ads?

In Demand Gen you can choose specific channels, such as YouTube Shorts only. Other campaign types may include Shorts among several surfaces.

How long should a Shorts ad be?

Google recommends under 60 seconds. The first second matters most because viewers swipe past quickly.

How are Shorts ads billed?

Under CPV, a view counts at 10 seconds or a call-to-action click, like, comment, or share. Under Target CPM, an impression counts when the ad starts playing.
