Trust Signals
Design elements that increase user confidence in a product's reliability, security, and legitimacy.
Plain English
Users arrive at unfamiliar products with healthy scepticism. Trust signals are the design elements that reduce that scepticism: customer logos ("Used by Google, Stripe, Airbnb"), testimonials, security badges, clear pricing, and no-dark-pattern design. The absence of trust signals — or the presence of dark patterns — compounds distrust rapidly. Trust is built incrementally and destroyed instantly.
Research background
Categories of trust signals: (1) Social proof — testimonials, review counts, customer logos, user counts. (2) Authority markers — certifications, press mentions, awards. (3) Security — SSL indicators, payment brand logos (Visa, PayPal), SOC2/GDPR compliance badges. (4) Transparency — clear pricing (no hidden fees), explicit privacy policy links, company info. (5) Consistency — professional visual design, working links, fast load times. (6) Reciprocity — free trial, money-back guarantee.
UI examples
✓ Applying the principle
A checkout page showing: SSL padlock, payment brand logos, "30-day money-back guarantee", and 5-star review count — all reducing friction before the final click.
✗ Violating it
A checkout that adds fees in the final step that were not shown earlier — destroys trust immediately and causes abandonment + negative word-of-mouth.
AI Prompt
Paste into Claude, Cursor, Bolt, or v0.
Add trust signals: 3-5 recognisable customer logos above the fold, a 5-star review count near the CTA, explicit security badge near payment fields, and a 30-day guarantee statement. Remove any element that could be perceived as a dark pattern.
