Social and Digital
Digital marketing uses both online and offline digital means to reach out to the target audience, while social media marketing is limited to online boundaries. Your digital media marketing campaign may use a variety of channels such as mobile advertisements, TV, online advertising, SMS, etc.
Digital social networks are a specific type of social network. Social networks, at large, refer to any interpersonal connection. Direct social networks include friends and family, while digital social networks pertain to the web. ... Your Facebook and Twitter accounts are prime examples of digital social networks.
Social media interaction involves businesses talking to individuals, primarily on Twitter, but also on Facebook, Instagram, and LinkedIn too. This interaction can be both reactive (to people who have messaged your brand) and proactive (to people you reach out to based on one or more factors).
