Product endorsement is a marketing strategy where a well-known person, often a celebrity or influencer, promotes a product or service. This endorsement aims to build trust and credibility, as consumers are more likely to purchase items recommended by someone they admire or relate to. Endorsements can take various forms, including advertisements, social media posts, or public appearances. Companies often choose endorsers who align with their brand values to reach specific target audiences effectively. Examples of endorsers include athletes like LeBron James or actors like Taylor Swift, who can significantly impact consumer behavior.
