What is Social Proof?
Social proof is the idea that people look to others for guidance when making decisions. Whether it’s customer reviews, case studies, or brand logos, social proof reassures potential users that they’re making the right choice. These elements are essential for building trust by showing that others—whether clients, investors, or partners—have already put their faith in your brand - specially in the early stages of a product/company.
