**Short answer:** YouTube Shorts ads run through Google Ads, mostly via Demand Gen and Video campaigns, and appear between Shorts in the vertical feed. Upload a 9:16 video to YouTube (unlisted is fine), keep it 15 to 30 seconds with the hook in the first 2 seconds, start with a modest daily budget and let it run a week. The same vertical file you use for Reels and TikTok usually works.

Shorts is the vertical feed most advertisers forget. That can be an advantage: fewer brands test creative there, and the same 9:16 ads you make for Reels and TikTok can run with almost no changes.

The catch is that Shorts ads live inside Google Ads, which has more campaign types and settings than Meta or TikTok. Here is the short path through it.

## How do YouTube Shorts ads work?

There is no separate "Shorts ads" product. Google Ads campaigns that include YouTube inventory can serve your vertical video between Shorts, the same way Reels ads appear between Reels. The campaign types most used for this are:

- **Demand Gen**, for conversions and reaching people across YouTube (including Shorts), Discover and Gmail.
- **Video campaigns**, for reach, views or conversions on YouTube.
- **Performance Max**, which can also place video on YouTube, with less control over where.

Google changes campaign names and options often, so check the current list in Google Ads before you build. The principle stays the same: give Google a vertical video and it can serve it in Shorts.

## What are the specs for Shorts ads?

| Spec | Recommendation |
|---|---|
| Aspect ratio | 9:16 vertical |
| Resolution | 1080 x 1920 |
| Length | 15 to 30 seconds for most ads; up to 60 seconds |
| Hosting | Upload to your YouTube channel (unlisted works) |
| Text | Upper third, away from the bottom controls |
| Sound | On by default; still burn in captions |

This is the same file that works on Reels and TikTok. Our [video ad specs cheat sheet](https://use-addy.site/blog/video-ad-specs-reels-tiktok-shorts) covers all three side by side.

## How much should you spend on a first Shorts test?

There is no fixed Shorts minimum, but Google's conversion bidding needs data. A practical first test is $20 to $50 a day for 1 to 2 weeks with 3 to 5 different videos, which is similar to a first Reels or TikTok test.

If you already run Meta or TikTok ads, start by reusing your two best performing vertical videos. You learn quickly whether Shorts viewers react the same way, without making anything new.

## What creative works in YouTube Shorts ads?

Shorts viewers swipe as fast as TikTok users, so the rules are the same:

- **Hook in the first 2 seconds**, spoken and on screen. Our [first 3 seconds guide](https://use-addy.site/blog/first-3-seconds-of-a-video-ad) has patterns that work.
- **Look native.** A person talking to the camera, a quick demo, a rant in the car. Polished TV spots get skipped.
- **One idea per ad.** Shorts are short; one problem, one product moment, one call to action.
- **Search-style intent helps.** YouTube viewers are often researching. "How I fixed X" and comparison angles tend to work better here than on TikTok.

If you need volume, AI ad tools can make vertical ads for all three feeds at once. Addy makes 15-second 9:16 ads from under $1 each and can post them to Shorts, Reels and TikTok.

## Shorts ads vs Reels ads vs TikTok ads: which first?

Start where your buyers already are and where you have tracking set up. For most consumer brands that is Meta (Reels) first, because its conversion tracking is mature. TikTok is strong for younger audiences and impulse buys. Shorts is often cheaper per view and good for products people research before buying.

The efficient path is one vertical creative workflow and three placements, tested one at a time. More on the trade-offs in [Shorts vs Reels vs TikTok](https://use-addy.site/blog/shorts-vs-reels-vs-tiktok).

## Frequently asked questions

### How do I run ads on YouTube Shorts?

Create a Google Ads campaign that includes YouTube inventory, such as Demand Gen or a Video campaign, and use a 9:16 vertical video uploaded to YouTube. Google can then serve it between Shorts.

### How long can a YouTube Shorts ad be?

Vertical ads are typically 15 to 30 seconds and can run up to 60 seconds. Shorter ads with a hook in the first 2 seconds are easier to test.

### Can I use my TikTok or Reels ads on YouTube Shorts?

Yes. The same 1080 x 1920 vertical file works, as long as it has no TikTok watermark and the text stays in the safe zone.

### Are YouTube Shorts ads cheaper than TikTok ads?

Often cheaper per view, but cost per result depends on your product and creative. Test both with the same videos and compare cost per purchase or lead.
