An endorsement deal is an agreement between a brand and an individual or organization to promote the goods or services of that brand. It involves the endorser leveraging their influence and reputation to increase the visibility and appeal of the product, which may provide benefits to both the brand and endorser. Endorsement deals are often used by companies to enhance their public perception by associating themselves with celebrities, influencers, or athletes who have a large following. They can also be used to attract younger audiences or those more likely to be influenced by endorsements. Ultimately, they help brands increase their sales and expand their reach.
