Digital Marketing and Social Media Marketing: The Difference, Explained Simply

If those two terms feel interchangeable, you are in good company. People use “digital marketing and social media marketing” as if they mean the same thing every day. They are closely related, they share tools and skills, and they often run side by side. But they are not the same size, and treating them as equals is how marketing budgets get lopsided. This guide sorts out what each one is, how they differ, how they fit together, and when to lean on one over the other.

Digital marketing and social media marketing at a glance

What is digital marketing?

Digital marketing is any promotion of a brand, product, or service that reaches people through digital channels. It is the umbrella term, and it is deliberately broad. Building a full digital marketing skill set means being comfortable across several channels at once:

• Search engine optimization (SEO)

• Pay-per-click and paid search (PPC)

• Email marketing

• Content marketing

• Websites and landing pages

• Video marketing

• Mobile and SMS marketing

• Social media marketing

The defining trait is coverage across the whole customer journey. Digital marketing is built to move a stranger from first discovery, through consideration, to a measurable action such as a purchase, a form fill, or a call. Because so much of it runs on direct-response channels like search and email, results are usually easier to attribute to specific spend.

One useful boundary: digital marketing is not strictly “online only.” A digital billboard, a rotating screen ad in a bank branch, or an SMS campaign is still digital marketing even though no browser is involved. Social media, by contrast, never leaves the platforms.

What is social media marketing?

Social media marketing is the practice of promoting a business specifically on social platforms. It covers organic posting, community management, influencer partnerships, and paid social ads across networks such as Facebook, Instagram, LinkedIn, TikTok, X, YouTube, and Pinterest.

The scale here is the reason it gets so much attention. According to DataReportal, there were 5.79 billion social media user identities worldwide at the start of April 2026, equal to roughly 69.9 percent of the global population and about 94.7 percent of all internet users. The typical user is active on around 6.5 different platforms each month. DataReportal’s Digital 2026 report also notes that social media ads rank as the third most important source of brand discovery after search engines and TV, and the single top driver of brand awareness among people aged 16 to 34.

What social media marketing does best is relationship building. Its strength is not the click that closes a sale today, but the trust, familiarity, and community that make that sale easier later. Much of that work comes down to content that connects with an audience, so its natural metrics reflect that too: reach and impressions, follower growth, engagement rate, and audience sentiment, rather than pure conversion counts.

Is social media marketing part of digital marketing?

Yes. Social media marketing sits inside digital marketing as one of its channels. This is the point people miss most often, so it is worth stating plainly: social media marketing in digital marketing is a component, not a competitor.

Think of digital marketing as a toolkit and social media marketing as one of the tools. A brand can run digital marketing with no social presence at all, relying on SEO, email, and paid search. It cannot run “social media marketing” that somehow sits outside digital marketing, because the moment a campaign lives on a digital platform, it is digital marketing by definition. That is why the phrase “social media is a subset of digital marketing” shows up in almost every serious explanation of the two.

The difference between digital marketing and social media marketing, in detail

The comparison table above is the short version. Here is what actually separates them once you get past the definitions.

Scope and channels

Digital marketing spans many channels: search, email, websites, video, mobile, and social. Social media marketing lives on social platforms alone. This is the single biggest difference, and it drives most of the others. A wider surface area means digital marketing can reach people in more contexts, while social media reaches them in one specific context: while they are scrolling a feed.

How they find an audience

Digital marketing often works on intent. A search ad or an SEO page meets someone at the moment they are actively looking for a solution. Social media marketing works more on interest and identity. It reaches people based on demographics, behaviors, and what they engage with, usually before they are actively searching for anything.

Goals and metrics

Digital marketing goals tend to run the full funnel and are measured in conversions, return on ad spend, qualified leads, and revenue. Social media goals skew toward the top and middle of the funnel: awareness, engagement, community, and loyalty, measured in reach, follower growth, engagement rate, and sentiment.

Conversion and return on investment

Return on investment is generally easier to attribute in the broader digital channels. PPC, email, and SEO produce clean funnel data, so you can trace a dollar in to a result out. Social media influence is often indirect, nudging a purchase that gets credited to another channel later, so measuring its true return usually needs UTM tracking, attribution modeling, and branded-search lift to tell the full story.

How digital marketing and social media marketing work together

The strongest strategies do not choose. They connect the two so each covers the other’s weak spot.

Digital marketing supplies the infrastructure and the measurable conversion paths: a fast website, search visibility, email nurture, and paid campaigns that can be optimized against hard numbers. Social media supplies the human layer: real-time engagement, culture, trust, and a place for an audience to actually talk back. Discovery on social feeds interest, that interest flows into search and site visits, and those visits convert through the direct-response channels. Run well, the two create a loop rather than two separate line items.

There is also a risk argument for keeping both. A brand that depends entirely on one social platform is exposed to algorithm changes and rising ad costs it does not control. A broader digital mix, with owned channels like email and SEO, adds stability that social alone cannot provide.

When to use digital marketing, social media marketing, or both

• Lead into full digital marketing when the goal is measurable, full-funnel growth across many channels and you need clear attribution from spend to revenue.

• Lead into social media marketing when the goal is fast brand awareness, community building, or reaching a visual and video-first audience where relationships matter more than the immediate click.

• Use both, which is the realistic answer for most businesses, when you want measurable conversions and durable relationships at the same time. Social builds the audience and the trust, the wider digital stack captures and converts the demand.

For nearly every business, the honest recommendation is not one or the other. It is a digital marketing strategy that treats social media as one important channel among several, sized to the audience you are actually trying to reach.
