Explainer videos are good at getting people interested in a company, product, or service. They take something complicated and make it comprehensible in ninety seconds.
The harder question is whether a given video is actually working.
Answering it takes more than a view count. You need to know how far people watched, whether they engaged, and whether they did the thing you built the video to make them do. Here are the seven metrics that tell you.
1. View Count
The simplest measure: how many people started your video.
It’s a reach number and nothing more. It tells you nothing about whether anyone watched past the first five seconds.
Why it matters: a high view count means your promotion and distribution are working, and that the title and thumbnail are doing their job. It’s the top of the funnel — necessary, but not evidence of anything downstream.
2. Play Rate
Play rate is the percentage of people who saw the video on a page and chose to press play.
It isolates one specific thing: how compelling the video looks before anyone watches it.
Why it matters: a low play rate is a packaging problem, not a content problem. The fix is the thumbnail, the title, or where the video sits on the page — not the video itself. A high play rate means the preview is landing with the right audience.
3. Watch Time and Completion Rate
Watch time tells you how much of the video people actually see, and where they stop.
This is the most diagnostic metric you have. A consistent drop-off point is a specific, fixable problem — a section that runs long, a pace that sags, or a promise made in the opening that the middle doesn’t deliver.
Why it matters: completion rate is the closest proxy for content quality. People who watch to the end found it worth their time. If half your audience leaves at forty seconds, the video is either too long, too slow, or too slow to get to the point.
4. Engagement Rate
Engagement covers likes, shares, comments, saves, and playlist adds — everything a viewer does beyond watching.
Those actions mean the video prompted a reaction rather than just being consumed. Viewers who engage are far more likely to remember the brand.
Why it matters: engagement is the clearest signal that content connected. It also feeds distribution — social platforms and search engines both amplify content that generates interaction, so a well-engaged video keeps earning reach after you stop promoting it.
5. Click-Through Rate
Click-through rate measures how many viewers acted on the call to action — visiting the site, signing up, starting a trial.
Why it matters: CTR is where attention becomes intent. A strong rate means the video made a persuasive case and the CTA was clear. A weak one usually means one of two things: the CTA isn’t specific enough, or the video content doesn’t set up the action it’s asking for. Both are fixable without reshooting anything.
6. Conversion Rate
Conversion goes one step past the click: how many people who clicked completed the action — bought, subscribed, booked, installed.
Why it matters: this is the number that justifies the production budget. A high conversion rate proves the video didn’t just attract attention, it moved people to act.
A low conversion rate with a healthy CTR points at a mismatch — either the video promised something the landing page doesn’t deliver, or the post-click experience isn’t good enough to close. Worth checking before you blame the video.
7. Social Sharing and Reach
Shares tell you people found the video useful enough to put their own name behind it.
Why it matters: every share extends reach at zero additional cost, and shared content carries credibility that paid distribution can’t buy — people trust a recommendation from someone they know. A video with a strong share rate is compounding in a way that an ad never does.
Conclusion
Measuring an explainer video means reading these numbers together, not individually. Play rate, watch time, engagement, and conversion each point at a different part of the funnel, and the pattern across them tells you where the problem is.
Get that reading right and each video you make performs better than the last — not because you got luckier, but because you know what to fix.
