What type of marketing strategy uses desktops, laptops, tablets, and smartphones?

The chosen answer, digital marketing, is correct because it encompasses all forms of marketing that take place through digital channels, including the use of various devices like desktops, laptops, tablets, and smartphones. Digital marketing leverages online platforms and technologies to reach and engage consumers, allowing businesses to connect with their audiences through websites, social media, email, search engines, and more.

This strategy is inherently versatile and can target specific demographics based on online behaviors and preferences, which is a key advantage of digital marketing. In today's technology-driven environment, the ability to utilize various devices for marketing purposes maximizes outreach and engagement potential.

In contrast, traditional marketing primarily involves non-digital channels such as print media, radio, and television, while direct mail marketing focuses on physical mail to reach customers. Outdoor marketing refers to advertisements placed in public spaces like billboards or transit ads. None of these methods necessarily involve the widespread use of digital devices as digital marketing does.
