Most SaaS homepages say roughly the same thing: a headline about saving time, three icons, a screenshot of a dashboard. Visitors skim it and still don't know what the product does on a Tuesday afternoon. An explainer video exists to close that gap.
This article covers what an explainer is, why it works for software in particular, what the 2026 research says, and what a good one actually shows.
What an explainer video is, and what it isn't
An explainer video is a short film, usually 30 to 90 seconds, that answers one question: what does this product do for me? It names a problem, shows the product solving it, and ends with one next step.
It is not a full tutorial, which teaches someone who already signed up. It is not a brand film either, which is about mood rather than function. For software, the most common forms are:
- Product explainer. The real interface, animated and edited so the important moments are easy to follow.
- Animated concept explainer. Illustration or motion graphics, useful when the product works in the background and has little interface to show.
- Hero loop. A silent 10 to 20 second loop at the top of the homepage that shows the product in use.
Explainers are one of the most common kinds of business video. In Wyzowl's State of Video Marketing 2026, 68% of video marketers said they make explainer videos, second only to social media videos (69%).
People skim pages, but they will watch a short video
Back in 2008, Jakob Nielsen of Nielsen Norman Group estimated from browsing data that visitors have time to read at most 28% of the words on an average web page, and that 20% is more likely. Your carefully written feature list is mostly skipped.
Buyers say they prefer video for exactly this job. In Wyzowl's 2026 survey of consumers:
- 63% said they would most like to learn about a product or service by watching a short video. Only 12% chose reading an article, and 5% a sales call.
- 96% said they had watched an explainer video to learn about a product or service.
- 80% said they had bought or downloaded an app after watching a demo of it.
On the company side, 93% of the video marketers in the same survey said video had increased people's understanding of their product, and 57% said it had reduced the number of support questions they receive. These are self-reported answers, so treat them as direction rather than a forecast.
Why it works: words and pictures together
Learning research gives a simple reason. Richard Mayer, whose work on multimedia learning spans more than three decades, sums up the core finding in a 2024 review in Educational Psychology Review: people learn better from words and pictures than from words alone.
The same body of research adds a warning, called the coherence principle: cut material that doesn't serve the point. Decorative backgrounds, stock footage of people smiling at laptops and long logo animations all compete for the same attention as your product.
For a SaaS explainer, that turns into three rules:
- Show the real interface, so what people see in the video matches what they see after signing up.
- Let a short line of text or voiceover say what is happening while the picture shows it.
- Remove anything that doesn't help someone understand the product.
What a good SaaS explainer shows
A 30 to 60 second explainer has room for one job done well. A structure that works for most software:
- The first seconds: the outcome or the problem. "Month-end in ten minutes, not two days." Not the logo, not a slow fade-in.
- The product doing one job. The real screens, in order, with the camera moving to wherever the important click happens.
- One moment of proof. The total appears, the report sends itself, the conflict resolves. This is the frame people remember.
- One extra capability, briefly. Something that answers the next obvious question, such as integrations or collaboration.
- An end card with one action. Start a trial, book a demo or download the app. One, not three.
Two practical details. Write the on-screen text so the film makes sense with the sound off, because plenty of people watch that way, especially on social media. And plan the formats from the start: Wistia's State of Video Report 2026 found that 76% of teams adjust the aspect ratio depending on where they post. A 16:9 cut for the website and a 9:16 cut for phones is the usual minimum.

Where to put it
- Homepage. Wistia's 2026 data shows videos on homepages, video galleries and product pages get the highest play rates.
- Pricing or product page. Where people are deciding.
- Sales follow-up emails. A link to a 45-second film is easier to forward to a colleague than a PDF.
- Onboarding emails. New sign-ups see what good looks like before they start clicking.
- Social posts and paid ads. Using the vertical cut.
What this means for you
- If your product is easier to show than to describe, an explainer is likely to be the most useful single video you can make.
- Build it around one job your customers hire the product for, shown in the real interface.
- Get to the point in the first seconds, and make it work with the sound off.
- Order two formats from the start so the same film can work on your site and on phones.
- Measure it where it lives: compare sign-ups or demo requests on the page with and without it.
