Digital marketing is important because it allows businesses to reach and engage with consumers where they spend most of their time: online. Digital marketing includes a range of tactics and strategies, such as email marketing, social media marketing, content marketing, search engine optimization, and more, that can be used to reach consumers through the internet and other digital channels.

There are several reasons why digital marketing matters:

1. It's cost-effective: Digital marketing can be more cost-effective than traditional marketing because it allows you to reach a larger audience at a lower cost.

2. It's targeted: Digital marketing allows you to target your audience based on various criteria, such as location, interests, and behavior. This makes it easier to reach the right people with the right message.

3. It's measurable: Digital marketing provides a wealth of data that can be used to track the effectiveness of campaigns and identify areas for improvement.

4. It's convenient: Digital marketing allows consumers to access information and make purchases at any time, from any device.

In summary, digital marketing is important because it allows businesses to reach and engage with consumers in a cost-effective, targeted, and measurable way.
