Benefits of Explainer Videos, Backed by Data
What explainer videos actually do for a business, with real data on attention, conversions, onboarding, and search, plus how to capture the payoff.
An explainer video earns its keep for one reason. It gets a stranger to understand your product faster than any wall of text sitting on the same page, and understanding is the thing that turns a curious visitor into a buyer. I have made these for software teams and health brands who all swore their thing was too complex for a short video. It rarely was. A clear 60 to 90 second explainer lets someone grasp the offer and take the next step without emailing you three questions first. Here is what that actually buys a business, with the real numbers behind each claim, plus how to get the payoff instead of a pretty file nobody finishes.
What an explainer video actually is
An explainer video is a short film, usually 60 to 90 seconds, that walks a viewer through one idea using narration plus visuals. Those visuals can be animation, motion graphics, live action, or a screen recording of the product itself. The job is narrow: answer “what is this and why should I care” before the viewer loses interest. A peer-reviewed review in Frontiers in Communication defines them as short films that explain abstract concepts through storytelling and focused visualization, and notes they now serve marketing goals as much as teaching ones. That double duty is why they turn up on homepages and in help centers alike. If you want the full taxonomy of formats, we keep a running breakdown of explainer video types.
Why they work: comprehension is a visual problem
People process a picture with a voice over it differently than a paragraph. Text makes the reader do the assembly. A good explainer does the assembly for them, pairing a spoken line with the exact image that proves it, so the point lands in one pass instead of three. Psychologist Richard Wiseman ran a clean test of this in 2012. He took one script, recorded it as a plain talking-head clip and as an animated version with identical audio, then quizzed viewers afterward. The people who watched the animation retained about 15 percent more of the information and were about 66 percent more likely to share it. Same words. The difference was how the idea was shown.
This is the whole mechanism behind every benefit below. When comprehension goes up, everything downstream moves with it: attention, trust, conversion, fewer support tickets.
Benefit 1: They hold attention on the page
A video gives someone a reason to stop scrolling and stay. Wistia looked at the time visitors spent on its highest-traffic pages and found people spent about 2.6 times longer on pages with video than on pages without it. On the sample they studied, that was roughly seven minutes versus under three. Attention is the currency every other outcome is bought with. A person who stays is a person who can be persuaded. A person who bounces in four seconds never gets the chance.
Benefit 2: They make a complicated thing click
The harder your product is to explain in a sentence, the more a video earns its place. Abstract software, a new financial mechanism, a medical device, a platform that only makes sense once you see it in motion. Text forces the reader to hold five concepts in their head at once and connect them without help. A video introduces them one at a time, in order, with a picture attached to each. I have watched a founder spend a full paragraph explaining what their tool does and lose the room, then watched the same idea land in twenty seconds of screen recording with a calm voice on top. The comprehension gain is the point; everything commercial follows from it.
Benefit 3: They build trust and lift conversions
Seeing a product work removes the worry that it might not. That is why the classic conversion case studies all involve a video sitting at the moment of decision. Dropbox is the famous older example: a simple homepage explainer that walked people through a then-unfamiliar idea, which the company credited with lifting sign-ups by around 10 percent and helping drive millions of early users. Crazy Egg reported that its explainer pushed conversions up roughly 64 percent and added about $21,000 a month in revenue. Rypple, later Work.com, logged around a 20 percent conversion lift after adding one to its homepage. Treat the exact figures as dated, because they are, but the direction has held for over a decade.
Buyer behavior explains why. Google’s research on shopping journeys finds people leaning on video to discover products and choose between them, with around half of the shoppers it surveyed saying online video made them aware of a brand and close to 45 percent saying it helped them decide which one to buy. A clear explainer on the page is meeting people where a lot of purchasing decisions already get made.
Benefit 4: They cut onboarding friction and support load
The video keeps paying after the sale. A new customer’s first ten minutes decide whether they stick, and a short welcome video that shows the first win beats a wall of tooltips every time. Support works the same way. Every question your team answers twenty times a week is a question a two-minute video can answer once, on demand, at 2am, without a ticket. I have seen support queues visibly thin out after a company dropped three short walkthroughs into its help center. If onboarding is the leak you are trying to plug, we go deep on it in how to improve your customer onboarding process.
Benefit 5: They pull in search and AI answer traffic
Search engines watch how long people stay, and video is one of the more reliable ways to keep them. A page that holds a visitor for two minutes reads as more useful than one they abandon, and that signal can help rankings for the terms you care about. There is a second surface most teams forget. YouTube is the largest video search engine on the planet, so a well-titled explainer can be found there and on Google at the same time, from one piece of work. And there is a newer reason worth naming. AI answer engines increasingly pull from pages that explain a topic cleanly and cite a real source, so a page built around a clear explainer with solid data is the kind of thing those systems quote. The last few clients who found us said outright they arrived through an AI answer or an organic search, so this channel is not theoretical anymore.
Which explainer video style fits which job
There is no single “explainer” look. The style is a strategic choice with real consequences, and picking wrong is how a video collects views but no results. A quick map of what each format is good at:
- Motion graphics: abstract or data-heavy ideas, software, fintech. Animated shapes and text make invisible things visible.
- 2D character animation: B2C and any story that benefits from a relatable protagonist with a problem.
- Whiteboard animation: teaching and step-by-step processes; the drawing-in-progress holds attention well.
- Live action: trust, testimonials, and physical products you want shown as real.
- Screencast: software walkthroughs and feature tours, where the product itself is the star.
If your decision is really animation versus filming real people, that trade-off has its own guide on animation vs live action. The clip below from Vidyard walks through where each video type sits in a marketing mix.
How long should an explainer video run?
Keep it to 60 to 90 seconds unless you have a specific reason not to. Completion falls off a cliff as videos get longer, and a benefit nobody watches to the end is not a benefit. Vidyard’s benchmark report, drawn from more than 1.7 million business videos, shows videos under a minute finishing at about 66 percent, while anything past ten minutes drops under 40. Short works because the viewer has a job to do and your video is a small detour they agreed to take. Respect that and they will finish it. For a fuller treatment, see how long an explainer video should be.

How to actually capture these benefits
A video only pays off if it is built and placed with intent. The parts that matter most:
- One idea. Pick the single thing a viewer must understand and cut everything else. Two messages means neither lands.
- A hook in the first five seconds. Open on the problem the viewer already feels, not your logo.
- The right home. Homepage for the broad pitch, product pages for specific features, a landing page for a campaign, and inside sales emails where a rep can send it as a follow-up.
- Silent autoplay support. Most feeds play muted, so the video has to read with captions on and sound off.
- One call to action. End by telling the viewer the single next step, whether that is a demo or a reply.
The production side, script through sound, is where quality is won or lost, and a custom animated piece usually runs four to eight weeks. What stretches that is the script and the review rounds, not the animation, so locking the message early is the fastest route to a good result. Our full walkthrough lives in how to make an explainer video.
How to measure whether it paid off
Views are the number that feels good and tells you the least. The metrics that matter track behavior, not eyeballs. Play rate tells you whether your thumbnail and placement are working. Completion rate tells you whether the story holds. Call-to-action clicks tell you whether it moved anyone. From there, connect the video to the funnel: compare conversion on pages that carry the explainer against pages without it, and watch whether viewers turn into demos and demos into pipeline. The goal is a sentence like “the explainer drove 500 demo sign-ups last quarter,” not “we hit 10,000 views.” We break down the formulas in video marketing ROI.
So, is it worth it?
For most companies with something that takes more than a sentence to explain, yes, and the evidence has pointed the same way for years. The awkward part shows up after you decide, because it is almost never one video. You want a homepage explainer, then a product-page version, then onboarding clips, then social cuts, and the appetite grows once the first one works. Producing that as a run of disconnected one-off projects is where quality and brand consistency tend to fall apart. Moonb exists for the other model, an embedded creative team with a dedicated Creative Director who makes this work continuously and keeps it looking like one brand. Whatever you choose, build the first explainer to be watched to the end, and put it where the decision actually happens.
Frequently asked questions
More than one, in almost every case I have seen. A homepage explainer answers 'what is this.' A product page wants a version zoomed in on one feature. Onboarding wants its own short clips, and social wants cut-downs sized for muted feeds. Most teams start with a single hero explainer and grow into a small library as each one proves out, so it helps to build that first video to be re-cut and extended rather than as a one-time showpiece.
An explainer sells the idea; a demo shows the mechanics. The explainer is short, usually 60 to 90 seconds, and lives at the top of the funnel to answer why someone should care. A demo runs longer and sits later in the buying process, walking through how the product actually works on real screens. Plenty of companies need both: the explainer to earn the click, the demo to close the loop for a buyer who is already interested.
For a custom animated explainer, plan on four to eight weeks from kickoff to final cut. That window covers scripting, storyboarding, a voiceover pass, animation, and sound design. What usually stretches it is the script and the number of review rounds, not the animation itself, so getting the message locked early is the fastest way to a strong video. A screen-recorded walkthrough can move quicker; heavy character animation takes longer.
