What works in YouTube Shorts ads
Shorts viewers are on YouTube, and YouTube is where people go to learn things. Ads that teach or explain something in a few seconds tend to do better here than pure hype. "Here's why this honey is thicker than the one you buy at the supermarket" is a Shorts ad.
The specs
| Setting | Use this | Notes |
|---|---|---|
| Aspect ratio | 9:16 | Horizontal ads are shown in Shorts too, but look out of place |
| Resolution | 1080 x 1920 | 720 x 1280 is fine for testing |
| Length | 15 to 30 seconds | Shorts can be longer, but most ads that hold people are short |
| Sound | On | Shorts is a sound-on feed |
| How to run it | Google Ads video campaign | Upload the video to YouTube first, then use it in the campaign |
Google changes ad formats often. Check Google Ads Help for the current Shorts placement details.
Longer can work on Shorts
TikTok and Reels punish anything that drags. Shorts viewers are a little more patient if the video promises to teach them something. That makes Shorts the natural home for AdVideoLab's longer renders: Seedance 2.5 goes up to 30 seconds in a single take, which is enough for a hook, a demo, a reason to believe and an offer.
| Length | Good for |
|---|---|
| 10 to 15 seconds | Simple products, retargeting, a single benefit |
| 15 to 20 seconds | A demo plus one proof point |
| 20 to 30 seconds | Products that need explaining, before and after, comparisons |
A structure that works
- 0 to 2 seconds: the question or the problem. "Why does cheap honey crystallise?"
- 2 to 10 seconds: the answer, with the product on screen.
- 10 to 20 seconds: one proof. A texture close-up, a test, a comparison.
- Last 3 seconds: one call to action.
Making Shorts ads with AdVideoLab
Pick UGC creator for a presenter who explains the product, or Single image for clean product shots. For videos longer than 15 seconds, choose Seedance 2.5 on the Generate page. Write with AI paces the voice-over to the length you pick, so a 30-second ad doesn't end mid-sentence.
