One thing I know to be true after 13 years in marketing: trust is the currency of what we do. Customers are increasingly skeptical of traditional ads and sales pitches—not to mention new technologies and AI are making us all question the content we’re consuming. Viewers crave authenticity—and in my experience, nothing delivers it better than video testimonials. When I’m marketing a new brand, one of the first tools I reach for is human-focused video content. Featuring real customers, employees, and verified experts creates relatability, credibility, and trustworthiness.
In this post, we’ll explore exactly what testimonial videos are, and why they are an essential part of any marketing strategy.
Social Proof: What Is it?
Social proof is the psychological concept that people tend to follow the actions of others, especially when uncertain. When potential customers see others praising your product or service, they feel reassured and more inclined to trust you.
Testimonial videos take social proof to the next level. Unlike written reviews, videos capture tone, emotion, and authenticity, making them significantly more persuasive.
In fact, 72% of customers trust a brand more when it features positive video testimonials and reviews. And even more impressive: Testimonial videos on sales pages can boost conversions by up to 80%.
What Are Testimonial Videos?
Testimonial videos are interview-driven stories that spotlight a compelling subject talking about your brand, service, product, or business. Often, they are created by conducting an interview with the subject of your video, who speaks directly or indirectly to the camera. Testimonial videos can stand on their own, i.e. the entire video is composed of the interview footage. But in my experience, the most compelling testimonial videos feature a combination of interview footage, on-screen graphics and text, and supporting b-roll or stock footage that helps tell the story alongside the interview.

The other thing to know about testimonial videos is that they don’t always have to feature a customer (though certainly a customer repping your product or service will capture attention and convert). I’ve had a ton of success producing testimonial videos that feature a trusted expert with relevant experience in a brand’s space; for example, interviewing a nutritionist to talk about the benefits of a new protein supplement and how it fits into a weight training program. These expert-driven testimonials add another layer of credibility to your brand’s story by providing consumers with a human perspective that’s backed by verified experience or education.
Another format I’ve had success with is producing internal testimonial videos for employee recruitment and retention. This type of testimonial typically features an engaging employee or member of a company’s leadership team talking about their career and experience. These videos make great assets for internal events or recruitment campaigns.
What Makes a Testimonial Video Great?
No matter if you’re looking to capture a client or customer’s story, an expert’s perspective, or the experience of a current employee, there are a few characteristics that all of the best testimonial videos share:
They deliver emotional impact: Your testimonial videos should capture genuine emotion and come across as relatable and persuasive without being overly sales-y
They read authentic: Producing videos via real-life interviews helps ensure the answers you receive from your subjects are genuine, which is essential to capturing (and keeping) your audience’s attention
They’re engaging to listen to and watch: Choosing subjects that are animated, articulate, and genuinely enthusiastic will help deliver your intended message in a compelling way. And incorporating elements like animations and b-roll or stock footage also helps drive visual interest.
Top Benefits of Testimonial Videos
Video content has been a table stakes component of every marketing strategy I’ve crafted in the past ten years. But after producing several different testimonial videos featuring all sorts of different subjects and topics, I’m convinced this particular medium is one of the most engaging and best converting assets a business can offer. Here’s why:
Testimonial videos drive credibility and trust
Customers trust real people more than brands
Real-life stories read more authentic than marketing jargon
Testimonial videos boost engagement and visibility
Videos have been proven to capture attention more effectively than text-only content
Video content ranks higher on search engines than text-only content
Video content also increases dwell time on your pages
Testimonial videos humanize your brand
There is a lot of skepticism of overly sales-y content as well as AI: featuring real humans adds an emotional, personal touch to your marketing
Testimonial videos are multi-purpose assets
Producing a testimonial video is never a one-and-done project: The asset can be chopped up and reconfigured across all of the other channels you care about, from social media and email campaigns to paid social ads
Testimonial videos help influence buyer decisions
Testimonials act as persuasive, word-of-mouth marketing
Viewers are more likely to purchase after seeing positive experiences
Testimonials can help overcome objections you anticipate to your offering
The Bottom Line
Video testimonials are an incredibly powerful marketing tool. They humanize your brand, build trust, and boost conversions. By showcasing genuine customer experiences, you can create an emotional connection that other marketing content alone simply can’t accomplish.
