How to write a 30 second marketing video script that holds attention

A good 30 second marketing video script does four things in order: it stops the scroll with a strong hook, names a problem the viewer recognises, shows how you solve it, and ends with one clear next step. Write those four beats before you film, and even a video shot on a phone can hold attention to the very end.

The script is where most small business videos are won or lost. Without one, filming turns into a long afternoon of retakes and the edit becomes a rescue mission. With one, you know what to say, what to show and when to stop.

What makes a good video script for a short marketing video?

A good video script is short, visual and built around a single message. It describes what the viewer sees, what they hear and what text appears on screen, moment by moment.

For short videos the script matters even more than for long ones, because there is no time to recover from a slow opening or a muddled point. A clear script also lets someone else, a colleague, a freelancer or an editor, understand the video without a long briefing.

It does not need to look like a film script. A few lines split by time, with a note next to each one about the picture, is usually enough.

How do you structure a 30 second video script?

Split the 30 seconds into four beats: hook, problem, proof and call to action. Treat the timings below as a guide rather than a stopwatch. Their real value is showing you which part of the script is running long.

The hook: roughly the first three seconds

Its only job is to stop people scrolling. Skip the logo, the “hi everyone” and the company introduction. Lead with a surprising image, a direct question or the end result, right from the first frame.

The problem: up to about ten seconds

The viewer should think “that’s me”. Describe the problem the way customers describe it, not the way your industry does. A physiotherapist might say “your neck is stiff by Wednesday”, not “cervical tension caused by poor workstation ergonomics”.

The proof: up to about 22 seconds

Show, don’t claim. Film the process, the product in use, a before and after, or a real customer explaining what changed for them. One piece of proof people can see beats three slogans.

The call to action: the final seconds

Ask for one simple action that fits the platform: send a WhatsApp message, book through the link, save the video for later. Two calls to action usually means neither gets done.

How do you write a hook that stops the scroll?

A hook works when the picture and the first line create curiosity or instant recognition together. Here are some reliable patterns for small businesses:

• Start with the result: a florist opens on the finished wedding bouquet, then rewinds to the bare stems.
• Ask the customer’s own question: “Why does my sourdough come out flat?” for a baking school.
• Call out a common mistake: “Stop washing your car in direct sun” for a car detailing service.
• Show something people rarely see: a restaurant kitchen five minutes before the doors open.
• Make a specific promise: “How to pack a suit so it arrives without creases” for an online menswear shop.

Write three hooks for every script and film them all. It adds a minute on the day and lets you test which opening keeps more people watching.

Writing your video script step by step

The easiest way to write a script is backwards: decide what the viewer should do, then build the shortest path to it.

1. Pick one viewer and one goal. For example, a new parent looking for baby swimming lessons nearby, and the goal is a WhatsApp message.
2. Write the call to action in one sentence that suits the platform.
3. Write the problem in the customer’s words. Real messages, reviews and comments are the best source.
4. Choose one piece of proof you can actually film.
5. Write three hooks and pick the strongest for your main version.
6. Break the text into shots. Next to each line, note what we see and what text is on screen.
7. Read it aloud with a timer. If it runs long, cut words. Don’t talk faster.

Example: a 30 second script for an accounting practice

Short video works for business services too. Here is a script for a small accounting practice that wants more freelance and sole trader clients:

• Hook, 0 to 3 seconds. We see a kitchen table buried in receipts next to a laptop. On screen: “Tax return due soon?”
• Problem, 3 to 10 seconds. Voice: “You started a business to do the work you love. Not to spend your Sundays sorting receipts.”
• Proof, 10 to 22 seconds. We see a client photographing a receipt with their phone, then the accountant walking them through a one page monthly summary. Voice: “Snap your receipts as you go and we take it from there. Every month you get one clear summary, in plain language.”
• Call to action, 22 to 30 seconds. On screen: “Message TAX on WhatsApp”. Voice: “Want your Sundays back? Send us the word ‘tax’ on WhatsApp and we’ll show you how it works.”

Why does it work? The problem is specific and a little emotional, the proof is something you can see, and the keyword in the call to action does two jobs: it lets a WhatsApp bot reply instantly, and it tells the CRM which video the lead came from.

Should the script change for ads, Reels and Stories?

The four beats stay the same, but the emphasis shifts. An organic Reel can lead with value, teach something or tell a story, and finish with a soft call to action such as “save this” or “follow for part two”. A paid ad reaches people who have never heard of you, so it should make the brand and the offer clear earlier and ask for one concrete action that matches the campaign goal.

Stories are watched in quick taps, so keep each segment short and the on screen text large. Whatever the format, assume many people watch with the sound off and write the on screen text as part of the script, not as an afterthought.

What are the most common video script mistakes?

• Opening with a logo, a greeting or the company history
• Squeezing three messages into one video: a sale, a new service and new opening hours
• Industry jargon your customers never use
• Lines written for reading rather than speaking, full of long clauses
• Telling everything and showing nothing
• A vague call to action like “find out more”
• No captions or on screen text

A quick checklist before you film

• The message fits in one sentence
• The hook works without sound
• The problem is described in the customer’s words
• There is proof you can see on camera
• There is one call to action that suits the platform
• The script has been read aloud and fits the time
• On screen text is written out, not improvised on the day

How do you get more videos out of one script?

Once a script works, reuse it. Film the three hooks as separate versions. Swap the proof for a different customer or product. Change the call to action for each platform. One afternoon of filming from a handful of solid scripts can fill weeks of posting, especially if you run a simple content system for Instagram and TikTok.

AI tools can help as well, from suggesting hooks and tightening lines to producing simple clips, as we explain in AI video for small business. They work best when you give them what they cannot know on their own: what your customers say and what makes you different.

Scripts first, cameras second

A 30 second video does not need a big production. It needs a clear video script: a hook that stops the scroll, a problem people recognise, proof they can see and one step at the end. At Kaede Digital we write, film and edit short videos as part of our social media management service, and we connect every call to action to WhatsApp and the CRM, so each interested viewer gets an answer straight away.

FAQ

How many words fit in a 30 second video?

Fewer than most people expect, because the best short videos leave room for moments where the picture does the talking. The reliable test is to read the script aloud at a relaxed pace with a timer. If it runs over, cut words rather than speeding up.

Do I need an actor, or can I appear in the video myself?

For most small businesses, the owner or a team member is the most convincing presenter, because they know the work and sound genuine. A script helps people who feel awkward on camera, since they know exactly what to say. You can also make videos with no face at all, using hands, products and process shots.

Can AI write my video script?

AI is a useful assistant for brainstorming hooks, tightening lines and writing variations of the same idea. It does not know what your customers actually say or what sets you apart, so give it that input and then edit the result into your own voice.

Should my video be 15, 30 or 60 seconds long?

Let the message decide. A single tip or a simple offer suits a very short video, while explaining a service or telling a customer story usually needs a little longer. The four beat structure stays the same; each beat simply gets shorter or longer.
