A PR agency strategizes and executes media activities to enhance your brand through press coverage, interviews, articles, and social media posts. These PR campaigns aim to establish credibility and reputation by utilizing storytelling, articles and leveraging media relationships. PR campaigns can be either one-time or implemented on a regular basis.
On the other hand, a digital marketing agency handles broader marketing channels as a whole. They organize events, launch products or services, manage online advertising, and sometimes, PR. Typically, a marketing agency employs a combination of promotional activities to strengthen your brand, but they don't always offer PR services.
