Social Media Marketing (SMM) is a marketing technique that goes through social media websites and applications to connect companies with their customers. By participating in social media through accounts and website integration, advertisers have more options to introduce their ideas to clients and present ads while giving customers an easy way to share content.

In many ways, SMM provides a similar construct to word-of-mouth advertising, as it relies on customers sharing information with other potential customers to spread awareness of a product or service.
