Teams often frame this as a decision — should we collect written reviews or video testimonials? The more useful question is where each one actually does the most work, because in most cases the right answer is both, deployed differently.
What written reviews are good at
Written reviews are cheap to collect at volume — a short form or a one-line request gets far higher response rates than asking someone to record video. They also directly support SEO: structured review markup (like schema.org's Review type) can surface star ratings in search results, and a page with dozens of specific written reviews gives search engines genuinely unique content to index. If your goal is breadth — a reviews page, star ratings across many products, social proof at scale — written is the more efficient format.
What video is good at
Video testimonials carry more trust per piece of content. A real person's face and voice is harder to convincingly fabricate than a paragraph of text, and viewers register that difference even if they couldn't articulate why. This is exactly why video performs disproportionately well as ad creative and at high-intent decision points — a visitor on your pricing page who's already interested benefits more from watching someone like them explain a specific outcome than from reading another star rating.
A simple placement framework
- Homepage and category pages — written reviews at scale, star ratings, aggregate proof.
- Product and pricing pages — one or two specific video testimonials near the CTA.
- Paid ad creative — video, almost exclusively; text doesn't translate to ad formats the same way.
- SEO-focused review pages — written, with structured data markup.
They compound, they don't compete
The mistake is treating this as either/or and picking one collection method to run exclusively. A broad, low-friction written review ask captures volume from most customers. A separate, higher-touch video request — reserved for your most specific, most enthusiastic customers — captures the smaller number of clips worth turning into ad creative. Running both isn't twice the effort if each request is scoped to what it's actually for.
Ask everyone for a quick written review. Ask your best customers for thirty seconds of video. Use each where it actually converts.
Neither format replaces the other. The programs that get the most value from testimonials are the ones that stop treating this as a single decision and start treating it as two separate, complementary systems.
