Social Proof Stack

Multiple testimonials or UI screenshots of positive outcomes arranged as a vertical stack or grid. Usually 3-5 cards, each with a quote, star rating, and real name. The cards scroll or stack with implied motion. Why it wins: it layers credibility signals. A single testimonial is a claim; five testimonials is a pattern. The format performs naturally as a carousel ad unit on Meta, which gets organic double-tap engagement. Works especially well for apps with emotional purchase triggers where trust is the primary conversion barrier.
