Public relations (PR) involves shaping and maintaining a positive image for an organization or individual with various publics or stakeholders. A public can be anyone who has or will form an opinion about that client. PR professionals help enhance their client's brand identity, visibility, and relevance compared to competitors through strategic media and public relations efforts like media liaising, news conferences, analyst briefings, pitching, and tracking media coverage. PR is also a key part of successful marketing campaigns, so PR professionals should understand basic marketing concepts. Effective PR strategies include writing concise, third-person press releases with relevant contact details and attention-grabbing headlines.
