YouTube Shorts ads: how to plan inventory, creative and channel selection
Part of YouTube channel planning
The short answer
YouTube Shorts ads are short ads, with vertical video preferred, served in the Shorts feed between organic Shorts, and viewers can skip them at once by swiping. Google sells them through Demand Gen, Video views, Video reach, reservation, Performance Max and app campaigns. Because the ads sit between videos, channel choice works mostly through exclusions, adjacency reports and context rules.
Key takeaways
- Shorts ads appear between organic Shorts in the feed, not on one creator's watch page, so a channel list shapes Shorts delivery less than in-stream delivery.
- Six Google Ads campaign types can serve Shorts ads, but only some give a Shorts specific switch or channel control.
- Vertical 9:16 video is Google's recommendation for Shorts; horizontal assets still deliver there when nothing vertical is supplied.
- On Shorts, placement exclusions and content themes apply, while content type and keyword exclusions do not.
- The content suitability report shows the content before and after a Shorts ad, which is the closest view a buyer gets of Shorts context.
What is a YouTube Shorts ad, and where does it appear?
Definition
- YouTube Shorts ad
- A skippable ad shown in the YouTube Shorts feed, between organic Shorts videos. Google describes the feed as a mobile optimized experience built around short, vertical, full screen videos.
YouTube's video ad formats page (opens in a new tab) says Shorts ads are rendered and appear randomly between organic Shorts videos, and that viewers can skip them immediately by swiping up or down. They serve on desktop, tablets and mobile web and apps, and on connected devices such as streaming devices, game consoles and TVs. The same page classes Shorts ads as out-stream under the IAB's format terms, alongside in-feed and Masthead ads, while bumper and in-stream ads count as in-stream.
That position matters for planning. An in-stream ad runs inside a video a viewer chose, on that creator's watch page. A Shorts ad runs in a stream the feed assembles, between whatever Shorts come before and after it. The context a brand appears in is the neighborhood of the feed, not a single creator, and every decision about channels on this page follows from that difference.
Which Google Ads campaign types can buy Shorts inventory?
Google's campaign types page for Shorts ads (opens in a new tab) lists six types, and says Demand Gen, Video view, Video reach and YouTube reservation campaigns give reporting on Shorts activity and more control over running on Shorts. The others reach Shorts as one surface among many. The table sets out what each type offers a planner who wants Shorts on purpose.
| Campaign type | How Shorts is switched on | Notes from Google's documentation |
|---|---|---|
| Demand Gen | Channel controls: Let me choose, then YouTube Shorts | The clearest documented way to run an ad group on Shorts alone |
| Video views | Tick YouTube Shorts under Multi-format ads | Can be switched on or off while the campaign runs; Google recommends also supplying horizontal video |
| Video reach | Tick YouTube Shorts under Multi-format ads | Google's Shorts page says only the Efficient reach goal offers Shorts; its Video reach setup page also lists Shorts for Target frequency |
| YouTube reservation | Through a Google representative | Shorts reservation is available with YouTube Select Shorts |
| Performance Max | No Shorts specific switch documented | Shorts is one of many Google surfaces; Shorts placement exclusions and content themes do not apply |
| App Install and App Re-engagement | No Shorts specific switch documented | Shorts is one of many surfaces for app goals |
The Video reach row carries a conflict worth knowing. The Video reach Shorts guide (opens in a new tab) says Shorts ads are only available for Video reach campaigns with the Efficient reach goal, while the Video reach setup page (opens in a new tab) describes Target frequency as using bumper, in-stream, in-feed and Shorts ads. Confirm in the account before a Target frequency plan promises Shorts delivery.
What creative does a Shorts ad need?
| Question | What Google says | Source |
|---|---|---|
| Aspect ratio | Vertical 9:16 is recommended for Shorts, at 1080 by 1920 pixels for HD | Demand Gen asset specifications (opens in a new tab) |
| Horizontal only | Horizontal and square assets are supported, vertical ones are prioritized, and horizontal assets still deliver on Shorts if nothing vertical is supplied | Shorts previews (opens in a new tab) and the Video reach Shorts guide |
| Length | Keep videos roughly 10 to 60 seconds, with a variety of messages | Video reach and Video views Shorts guides |
| Shortest cut | Demand Gen video must run at least 5 seconds, and videos under 10 seconds cannot serve on YouTube in-stream | Demand Gen asset specifications |
| Checking the result | Preview how text and buttons appear on Shorts before launch | Shorts previews |
How does channel selection work when Shorts ads sit between videos?
Google's Shorts buying guides talk about audiences, not placements. The Video views Shorts guide (opens in a new tab) recommends keeping targeting broad, suggests interest based segments such as affinity and in-market audiences, and says custom search term segments and Infinite Taxonomy restrict serving on Shorts only campaigns. Neither guide describes picking a creator's Shorts with a positive channel placement. What the documentation does give buyers is a set of exclusions.
Google's content suitability page (opens in a new tab) shows which controls reach Shorts. Inventory type applies. Placement exclusions and excluded content themes apply, except in Video action and Performance Max campaigns. Content type exclusions and excluded content keywords do not apply to Shorts, and Google says content exclusions may provide limited coverage of YouTube Shorts.
| Use of the channel list | Works on Shorts? | How to use it |
|---|---|---|
| Exclusion list of refused channels | Yes, through placement exclusions in campaigns other than Performance Max | Load channels the brand refuses into an account level exclusion list |
| Context map for reviewing reports | Yes | Compare adjacency rows in the content suitability report with the plan's themes |
| Positive targeting of one creator's Shorts | Not described in Google's Shorts guides checked in October 2026 | Treat any channel inclusion as unconfirmed for Shorts until the account shows otherwise |
| Signal for the long-form side | Yes, for in-stream ad groups | Keep channel placements in separate in-stream ad groups where they carry real weight |
How is Shorts ad delivery reported?
Shorts reporting answers a different question from Watch page reporting. Google's content suitability report (opens in a new tab) uses adjacency reporting for Shorts: it shows placement data for content shown before and after a Shorts ad. Because one ad sits between two videos, impressions on Shorts are not deduplicated, so totals can run higher than served impressions. Counts in the report are not billed impressions and can include invalid traffic, and placements below minimum thresholds are left out.
Reading a Shorts adjacency report
- Filter to Shorts. Use the impression source view so Shorts rows are read apart from Watch page rows.
- Read the neighbors as a pair. Each ad has content before and after it; judge both against the brand's limits.
- Do not add up the rows. Shorts impressions are not deduplicated, so the sum overstates delivery.
- Move refusals to exclusions. Any channel that keeps appearing beside the ad and breaks the brand's limits goes on the exclusion list.
- Match to invoices for money. Google says invoices, not this report, are the source of truth for billing.
How should a Shorts plan handle made for kids content?
YouTube's made for kids advertising rules (opens in a new tab) prohibit personalized ads and remarketing on content set as made for kids, while contextual ads based on the content, the current search and general location are allowed. Some categories cannot run there at all, including beauty and weight loss, which YouTube describes as products related to external personal care, fitness products relating to weight loss, and diet and nutrition.
For Shorts, the practical control is the excluded content theme, which Google lists as applying to Shorts. Its Content Suitable for Families theme includes Made for Kids videos. A brand in a barred category, or one that simply wants to stay out of children's content, should set that exclusion at the account level and still read the adjacency report, since Google warns that exclusion coverage on Shorts is limited. Google's help pages gave two paths to the settings when checked in October 2026, Tools > Content suitability and Admin > Account settings; confirm in the account.
What does a Shorts plan look like for one brand?
Fictional example
A daily sunscreen brand plans Shorts in the New York City metro area
An unnamed skincare brand selling daily sunscreen for commuters asks for YouTube Shorts in the New York City metro area, in English, beside skincare routine, city life and fitness content, with no medical misinformation or shock content.
The planner builds a Demand Gen ad group set to YouTube Shorts only, with three vertical 9:16 cuts of different lengths, and a separate Video views campaign with Shorts ticked for horizontal and vertical assets together. Targeting stays broad with interest segments, following Google's Shorts guidance.
Because beauty products cannot run on made for kids content, the account excludes the Content Suitable for Families theme, and 30 refused channels go on the account placement exclusion list. Each week the team reads the Shorts adjacency rows and moves any repeat offender to the list.

What should be settled before a Shorts campaign launches?
Shorts launch checklist
- The campaign type and goal are confirmed to serve Shorts in the account, including any Target frequency plan.
- At least one vertical 9:16 asset is supplied, and previews show text and buttons clear of the Shorts interface.
- The account placement exclusion list holds every channel the brand refuses.
- The excluded content theme for family and made for kids content is set if the brand's category or policy requires it.
- Shorts and long-form are in separate ad groups or campaigns so their reports can be read apart.
- The team knows Shorts adjacency counts are not deduplicated and not billing figures.
Frequently asked questions
When is a Shorts ad charged as a view?
In Video views campaigns, Google says a viewer must watch the ad for at least 10 seconds, or to the end if it is shorter, for the view to count. That billing rule is separate from the public view count: YouTube says that since August 24, 2026 ad views add to public views the moment a Shorts or in-stream ad starts to play.
Can Shorts ads be reserved in advance?
Yes, through YouTube reservation campaigns. Google says Shorts ads in reservation campaigns are available with YouTube Select Shorts and that advertisers should contact their Google Ads representative to use them. Reservation buys follow their own terms, so agree content and suitability limits with the representative in writing.
Do Shorts ads appear on TV screens?
Yes. YouTube's ad formats page says Shorts ads serve on desktop, tablets and mobile, and on connected devices such as streaming devices, game consoles and TVs. Check that vertical creative reads well on a large screen, since logos and text sized for a phone can look different there.
Can Performance Max keep Shorts ads off certain channels?
Not through the Shorts controls on Google's content suitability page. Its coverage table lists placement exclusions and content themes on Shorts, except for Video action and Performance Max campaigns. A brand that needs channel level control over Shorts should buy them through Demand Gen, Video views or Video reach instead.
