Social proof
Evidence that other people already use and trust a product.
Social proof is any evidence on a page that other people have chosen a product: customer logos, testimonials, reviews and ratings, case studies, user counts or press mentions. It works because buyers look to others to reduce the risk of a decision.
It is most persuasive when it is specific and checkable: a named person, their company and the result they got, near the moment of decision. Vague praise and logos with no story behind them do less.
Key characteristics
- Logos, testimonials, reviews, case studies and numbers.
- Specific beats general: names, roles and results.
- Placed near decisions such as pricing and sign-up.
- Must be real and checkable to build trust.
Example
Under its sign-up button, a product shows one testimonial from a named customer with the result they got, instead of a wall of anonymous five-star quotes.

Frequently asked questions
Where should social proof go on a page?
Near the decisions it supports: under the main call to action, on the pricing page and beside forms.
What if a startup has no customers yet?
Use what is real: pilot users, a founder's track record, investors or a public waitlist number. Never invent it.
