Patterns: Social Proof
Patterns for leveraging social influence to build trust and encourage action.
What is Social Proof?
People look to others' behavior to guide their own decisions. When uncertain, we assume the crowd knows something we don't.
Core principle: Show users that others have chosen, trusted, and succeeded with your product.
Testimonials & Reviews
What: Direct quotes from satisfied users.
Types
| Type | Use Case |
|---|---|
| Quote testimonials | Brand credibility, landing pages |
| Star ratings | Quick quality signal |
| Written reviews | Detailed feedback, product pages |
| Video testimonials | High-trust, emotional impact |
| Case studies | B2B, complex products |
Psychological Principles
- Social proof — Others' positive experience signals quality
- Authority — Expert testimonials add credibility
- Similarity — Relatable testimonials more persuasive
Implementation Guidelines
DO:
