The script is where an explainer video is won. Good animation over a weak script produces an attractive video nobody acts on.
Here’s how to write one that holds attention and does its job.
Start With the Purpose
Before writing a line, answer three questions:
- What are you actually trying to communicate?
- Who is watching?
- What should they do afterwards?
The answers determine everything else. A video explaining how new software works needs to be instructional. A video built to drive sales needs to lead with the differentiator. They’re different scripts.
Define the Goal
A single defined objective keeps the script on track. Brand awareness, lead generation, traffic, or explaining something complicated — pick one.
Without that, scripts drift. With it, every line has a test to pass: does this serve the goal?
Identify the Audience
Age, role, technical fluency, and the problem they’re trying to solve all shape how you write.
A video aimed at time-pressed professionals should lead with hours saved. One aimed at a technical audience can go deeper into capability without losing them. Same product, different scripts.
Keep It Short
Target 60–90 seconds, which is roughly 150–200 words.
That constraint is a feature. A script that has to fit 180 words can’t include anything unnecessary, which is why short explainers tend to be sharper than long ones.
Cut the Jargon
Technical vocabulary loses people who aren’t already inside your category.
“Our software uses artificial intelligence algorithms” tells a general audience nothing. “Our software uses smart technology to help you work faster” tells them what changes for them. Where a technical term is genuinely necessary, define it in the same breath.
Focus on One Message
One central point per video. Trying to cover everything dilutes all of it.
If the video is about a new app, lead with the problem it solves rather than walking the feature list. Features support the message; they aren’t the message.
The Five-Part Structure
Most effective explainer scripts follow the same shape.
1. Hook
The first few seconds decide whether anyone watches the rest. Open with something that creates a question in the viewer’s head.
A surprising statistic works: “70% of companies struggle to keep up with social media.” So does a direct promise: “What if you could get ten hours a week back?“
2. Problem
Name the problem specifically enough that the viewer recognises their own situation in it.
“Managing social media is time-consuming and difficult, especially for a small team with no dedicated marketer.” A viewer who thinks that’s me is now paying real attention.
3. Solution
Introduce your product as what resolves it. Be concrete about the benefit and about what makes you different from the obvious alternative.
“Our platform makes growing your online presence straightforward — scheduling, publishing, and analytics in one place.”
4. How It Works
Show the mechanism in a few plain steps. This is where the visuals do most of the work.
“Connect your accounts, choose what you want to publish, and the platform handles the rest — with real-time performance data as it goes.”
Three steps is usually the right number. More than four and you’ve moved from explaining to instructing.
5. Call to Action
Close by naming the next step explicitly.
“Start a free trial and take the first step toward social media that manages itself.”
Write It Conversationally
Write the way you’d explain it to a colleague, not the way you’d write a brochure.
The practical test: read the script aloud. Anything you stumble over is a line that needs rewriting, because the voice actor will stumble over it too.
Build In Variation
A script delivered in one flat register loses viewers regardless of the visuals.
Write for changes of pace. Use short sentences for emphasis and deliberate pauses before the important points — “Imagine never thinking about scheduling posts again. That’s what this does.”
Engage the Viewer Directly
Questions make people apply the content to themselves. “Ever wished there were an easier way to handle all this?” invites the viewer to answer rather than just receive.
Use a Story
A short narrative — someone with the problem, what they tried, what changed — is more memorable than the equivalent explanation.
Stories give the viewer somewhere to put themselves. That’s what makes the message stick after the video ends.
Conclusion
A good explainer script comes from knowing the goal, knowing the audience, keeping it tight, structuring it properly, and writing it to be spoken rather than read.
Get those right and the script does the persuading. The animation just makes it enjoyable to watch.
