A short video ad sells when the first three seconds stop the scroll with something the viewer cares about, the next ten seconds show the product solving a real problem, and the ending gives one clear action. It is built for silent, vertical viewing on a phone, with captions and the brand visible early. Most of the results come from the idea and the hook, not from expensive production.
On Meta, TikTok and YouTube Shorts, creative is now one of the strongest levers you control. Ad platforms automate targeting more and more; what they cannot do for you is make a video people want to watch. This checklist covers how we plan and produce short ads for clients and our own products.
| Part | Time | Job |
|---|---|---|
| Hook | 0–3 s | Stop the scroll with a problem, result or surprise |
| Problem | 3–7 s | Show the situation the viewer recognises |
| Solution | 7–20 s | Show the product or service doing its job |
| Proof | 20–25 s | A result, review, number or before/after |
| Call to action | Last 3–5 s | One clear next step |
For a 15-second ad, compress the middle. For a 30–45 second ad, add a second proof point or a short demo.
Most viewers decide within the first seconds whether to keep watching. Strong hooks:
Write five to ten hooks for each ad idea. Then film or edit several of them on top of the same body. Hook variants are the cheapest way to find a winner.
Many people watch with the sound off. So:
| Placement | Ratio | Notes |
|---|---|---|
| TikTok, Reels, Shorts, Stories | 9:16 | Keep text away from the top and bottom edges where buttons sit |
| Meta feed | 4:5 or 1:1 | Takes more screen space than 16:9 in the feed |
| YouTube in-stream | 16:9 | First 5 seconds before "Skip" matter most |
Plan the shoot so one recording can be cut into all three ratios: frame the subject in the centre and leave space around it.
For a test round we usually prepare:
From one shoot and a few hours of editing, that is a solid test set. Let the platform show the variants and look at the results after enough spend to learn something.
A video with a strong hook rate and weak clicks needs a better offer or call to action. A video with a weak hook rate needs a new opening, not a new body.

A great ad sent to a weak page wastes money. The landing page should repeat the promise of the video, ideally with the same visual or the video itself near the top. Read landing page for an ad campaign for the page side.
We plan, film and edit short ads in our video editing and animation service, design static and motion ad creative, and run testing as part of our ads strategy work. If your ads are not getting attention, send us a few current ads and we will suggest new hooks.
Most perform well between 10 and 30 seconds. Test a short and a longer version of the same concept.
Not to start. Authentic, well-lit phone footage with a clear message often performs as well or better. Invest in production once a concept is proven.
When performance drops as the same audience sees the ad repeatedly. Many accounts need new variants every few weeks.
Yes, with adjustments: correct ratio, safe zones for text, and a hook suited to each platform's style.
