Hello, I will share some suggestion about this amazing question. The customer reach is the potential number of customers your business can reach through any marketing channel or campaign. Digital marketing is an umbrella term for using digital tools to promote and market products, services, organization's, and brands. As consumers and businesses become more reliant on digital communications, the power and importance of digital marketing have increased. The direct marketing section of this module already discussed two digital tools: email and mobile marketing, which fit into both categories. This section will discuss other essential tools in the digital marketing tool kit: Web sites, content marketing, and search engine optimization (SEO), and social media marketing.
