Evidence that others have used and approved of your product or service.
Social proof is the psychological phenomenon where people follow the actions of others. In advertising, it builds trust and credibility.
Social proof — reviews, testimonials, user counts, and endorsements — is one of the most powerful persuasion tools in advertising. People trust other people's experiences more than brand claims. Ads and landing pages with strong social proof consistently outperform those without, especially when targeting cold traffic who don't yet trust your brand.
