Public relations involves planned efforts to build and maintain mutual understanding between an organization and its publics. It helps shape the organization's corporate image through controlled and uncontrolled media. An effective corporate image benefits an organization by stimulating sales, establishing goodwill, and promoting favorable relations with stakeholders. A corporate image is formed through internal efforts like advertising, branding, and employee behavior, as well as external factors outside an organization's control like industry reputation and press coverage. As part of its marketing activities, an organization must consider its target audience and devise an appropriate marketing mix of product, price, placement, and promotion.
