Public relations plays an important role in promoting organizations and managing their relationships and reputation with key stakeholders. It aims to build goodwill and distribute positive information about an organization through various communication tools and channels at a lower cost than advertising. Some of the main functions of public relations include press relations, product publicity, corporate communications, lobbying, and advising management. Common public relations tools include written materials, events, media relations, corporate identity materials, and community involvement. An effective public relations strategy incorporates two-way communication to understand stakeholder perspectives and help organizations address any issues before they become problems.
