Context: What is digital marketing and why people invest in digital marketing ?

Digital marketing refers to the use of the internet, mobile devices, social media, search engines, and other channels to reach consumers. It's a broad field, including attracting customers via email, content marketing, search platforms, social media, and more.

Here are the steps to explain why people invest in digital marketing:

1. Global Reach: Digital marketing allows businesses to reach a global marketplace. They can reach out to their target audience worldwide, which would have been impossible through traditional marketing.

2. Cost-Effective: Digital marketing is more cost-effective than traditional marketing. This is especially important for small businesses as they don't have many resources or a lot of capital.

3. Measurable Results: One of the reasons why digital marketing is taking over traditional marketing channels is the ability of Internet marketing tools to interact with targeted audiences in real time. Engagement in any form is what your customers expect to receive when interacting with your brand or business.

4. Higher Revenue: By driving more traffic to your site, you can achieve higher conversions. This, in turn, will get you more revenue.

5. Targeted Audience: With digital marketing, you can ensure that the right consumers are viewing your content. SEO allows you to reach those consumers who are searching the web for content and topics that are relevant to your business.

6. Building Brand Reputation: With digital marketing, you can attract more customers. The more satisfied customers you have, the more they will spread the word about your business. This will help you establish a better brand reputation.

7. Better ROI: Digital marketing can provide a better Return on Investments (ROI) than traditional marketing channels. With traditional media, the cost is too exorbitant for small and medium enterprises to leverage on, and the results are somewhat vague and difficult to measure. On the other hand, digital marketing can easily be tracked and monitored, with results immediately realized and measured as soon as targeted audiences provide contact information, subscribe to a newsletter or training program, or make a purchase.

In conclusion, the future of marketing is digital. With the numerous benefits of digital marketing, investing in it is a decision that all businesses need to make.
