Does social proof increase conversions? What owners measured after adding video
Based on interviews with Share One customers · August 12, 2026
Social proof is usually argued in the abstract. These interviews are the concrete version: owners describing what moved in their own funnel after they replaced text quotes with recorded customers.
The largest reported swing comes from Curt Maly, who buys media for a living and describes doubled conversions with ad costs cut roughly in half after switching to human testimonial creative. His framing is worth keeping: "Talking about human testimonials right now is probably 1 of the most critical things that people are gonna hear in 2025, 2026." Giovanni Santoriello reports a 30% lift in demo bookings. Sarah Phillippe describes more discovery calls landing in the diary within weeks of publishing.
Where video seems to matter most is late in the decision, not early. Several people describe sending a story after a sales call rather than before one — the prospect has already heard the pitch and now needs to hear it from somebody who is not selling. Others put stories on the pages where hesitation actually happens: pricing pages, booking pages, follow-up email.
For regulated and high-consideration purchases the effect people describe is different again. Clinicians in this set talk less about conversion rate and more about pre-qualification: patients arrive already understanding what the procedure or programme involves, which shortens the consultation and reduces the mismatch.
Treat the numbers here as self-reported and uncontrolled — nobody ran a holdout test. The value is in the direction and the consistency across very different businesses, from a law firm to an ad agency to a plastic surgery practice.
