Brand endorsement is a marketing strategy where a well-known person, often a celebrity or influencer, promotes a product or service. This association aims to enhance the brand's credibility and appeal by leveraging the endorser's popularity and positive image. For example, a famous athlete endorsing a sports drink can attract fans and boost sales. Companies often choose endorsers who align with their brand values and target audience. Successful endorsements can lead to increased brand awareness and customer loyalty. However, if the endorser's reputation suffers, it can negatively impact the brand, making careful selection crucial for effective brand marketing.
