An "Endorser" is a person or entity that publicly supports or recommends a product, service, or brand. This support can take various forms, such as testimonials, advertisements, or social media posts. Endorsers often have a significant influence on consumer behavior, as their approval can enhance credibility and attract potential customers. Endorsers can include celebrities, industry experts, or satisfied customers. For example, a famous athlete endorsing a sports drink can boost its popularity among fans. Companies often seek endorsements to leverage the endorser's reputation and reach a wider audience, ultimately aiming to increase sales and brand loyalty.
