Digital marketing helps businesses to reach and engage with a larger audience through the use of various digital channels, such as social media, search engines, email, and websites. These channels allow businesses to connect with customers, promote their products or services, and drive sales through targeted advertising, content marketing, and other tactics. Additionally, digital marketing allows businesses to track and measure their marketing efforts in real-time, making it easier to understand what works and what doesn't, and to adjust their strategy accordingly.
