Digital marketing is important because it allows businesses to reach and engage with consumers where they spend a significant amount of their time: online. Digital marketing channels include search engines, social media, email, mobile apps, and websites. These channels allow businesses to connect with their customers, track the success of their marketing efforts, and make data-driven decisions to improve their marketing strategies. Digital marketing also provides a level of accessibility and accountability that traditional marketing channels may not offer. It is cost-effective, measurable, and allows for personalized messaging, which makes it an essential part of any business's marketing strategy.
