What Is Digital Marketing?

Digital marketing refers to all forms of marketing that use the internet, mobile devices, or digital technologies to reach potential customers. Instead of traditional platforms like TV or newspapers, digital marketing focuses on online channels such as search engines, social media, email, websites, and mobile apps.

It is the most scalable and cost-effective way to promote products, build brands, generate leads, and drive sales.
