A brand ambassador (sometimes also called a corporate ambassador) is a person who is hired by an organization or company to represent a brand in a positive light and by doing so help to increase brand awareness and sales. The brand ambassador is meant to embody the corporate identity in appearance, demeanor, values and ethics. The key element of brand ambassadors is their ability to use promotional strategies that will strengthen the customer-product-service relationship and influence a large audience to buy and consume more. Predominantly, a brand ambassador is known as a positive spokesperson, an opinion leader or a community influencer, appointed as an internal or external agent to boost product or service sales and create brand awareness. Today, brand ambassador as a term has expanded beyond celebrity branding to self-branding or personal brand management. Professional figures such as good-will and non-profit ambassadors, promotional models, testimonials and brand advocates have formed as an extension of the same concept, taking into account the requirements of every company.
