Social media marketing (SMM) (also known as digital marketing and e-marketing) is the use of social media—the platforms on which users build social networks and share information—to build a company's brand, increase sales, and drive website traffic. In addition to providing companies with a way to engage with existing customers and reach new ones, social media marketing (SMM) has purpose-built data analytics that allow marketers to track the success of their efforts and identify even more ways to engage.
