What Is Social Media Marketing (SMM)?
Social media marketing (SMM) is the use of social media platforms to build a brand, increase sales, and drive website traffic. It allows companies to connect with customers, gather data, and measure the effectiveness of their marketing efforts in real time.
As of October 2025, there were more than 6 billion social media users worldwide, giving businesses unprecedented access to consumers.1 Because of its reach, targeting capabilities, and data analytics tools, social media marketing has become a core part of many companies’ marketing strategies.
Why Is Social Media Marketing (SMM) So Powerful?
The power of SMM is driven by the unparalleled capacity of social media in three core marketing areas: connection, interaction, and customer data.
Connection
Not only does social media enable businesses to connect with customers in previously impossible ways, but there is also an extraordinary range of avenues to connect with target audiences—from content platforms (like YouTube) and social sites (like Facebook) to microblogging services (like X).
Interaction
The dynamic nature of the interaction on social media—whether direct communication or passive liking—enables businesses to leverage free advertising opportunities from eWOM (electronic word-of-mouth) recommendations between existing and potential customers. Not only is the positive contagion effect from eWOM a valuable driver of consumer decisions, but the fact that these interactions happen on the social network makes them measurable. For example, businesses can measure their social equity—a term for the return on investment (ROI) from their social media marketing campaigns.
Customer Data
A well-designed social media marketing plan delivers another invaluable resource to boost marketing outcomes: customer data. Rather than being overwhelmed by the 3Vs of big data (volume, variety, and velocity), SMM tools have the capacity not only to extract customer data but also to turn this gold into actionable market analysis—or even to use the data to crowdsource new strategies.
How Social Media Marketing (SMM) Works
As social media platforms such as Facebook, Instagram, TikTok, YouTube, LinkedIn, and X have grown, businesses have increasingly used them not just for promotion but also for customer engagement, brand building, targeted advertising, and data-driven marketing.
SMM Action Plan
The more targeted your SMM strategy is, the more effective it will be. Hootsuite, a leading software provider in the social media management space, recommends the following action plan to build an SMM campaign that has an execution framework as well as performance metrics:2
- Align SMM goals to clear business objectives
- Learn your target customer (age, location, income, job title, industry, interests)
- Conduct a competitive analysis of your competition (successes and failures)
- Audit your current SMM (successes and failures)
- Create a calendar for SMM content delivery
- Create best-in-class content
- Track performance and adjust SMM strategy as needed
