A bad explainer video doesn't just fail to convert — it actively damages trust. Visitors assume the video reflects the product. If it's unclear or generic, so is the product in their mind. Here are the five mistakes that show up most often.
1. Starting with the product instead of the problem
The most common mistake. The video opens with your logo, your product name, and a tour of your dashboard. By the time you get to why any of this matters, the viewer has already decided it's not for them. Start with the problem. Make your viewer feel seen before you show them anything.
2. Trying to cover everything
Your product does a lot. Your explainer video should not. A 90-second video that tries to cover ten features ends up communicating none of them clearly. Pick one core value — the single most compelling thing your product does — and build the entire video around that. You can make additional videos for features later.
3. Using generic stock animation
Template-based videos look like template-based videos. When your explainer looks identical to your competitor's, it signals that your product is interchangeable too. Custom illustration and animation is more expensive, but it's one of the few places where visual differentiation directly impacts conversion.
4. Writing for readers, not viewers
Video scripts are not blog posts. Long sentences, passive voice, and technical jargon kill pacing. A good video script is written to be heard — short sentences, active voice, concrete language. If you wouldn't say it out loud in a conversation, it shouldn't be in the script.
5. No clear call to action
What do you want the viewer to do after watching? If your video ends with your logo and a tagline, you've wasted the last five seconds — the moment when intent is highest. End with one specific action: start a trial, book a demo, see how it works. One ask. Not three.
The fix
Most of these mistakes come from the same root cause — treating the explainer video as a product tour instead of a sales tool. The best explainer videos are built around the viewer's problem, not the founder's pride in their features.
