DEFINITION
One of the easiest way to quickly dismiss any argument that social media marketing and digital marketing are synonyms is using their definitions. Social media marketing involves promoting, advertising and creating awareness of a service or product using the social media only.
Digital marketing, on the other hand, involves promoting, advertising and creating awareness via all the available digital channels including offline marketing channels such as TV, radio and internet channels such as SEO among others. Basically, from their respective definitions, it is easy to conclude that social media marketing is a component of digital marketing simply by virtue of being fueled by the internet.
