The classic numbers say social proof drives conversion. The 2026 numbers add a twist: buying research is moving into AI assistants, where only machine-readable proof counts. Testimonials published as real text with Review schema and an llms.txt feed exist in those answers; screenshots don't. That's the gap Testivo closes — and you can measure your own starting point on the AI Rank leaderboards.
