Social media terms every SMM needs to know

There’s a conversation that happens in almost every marketing department.

Someone says, “We need to improve engagement,” and everyone nods. Nobody asks what kind of engagement, measured how, compared against what baseline. Everyone assumes they’re talking about the same thing.

They’re not.

That’s the weird problem with social media vocabulary: we use it constantly, and define it rarely. Terms travel through presentations, reports, and Slack threads with a confidence that hides real ambiguity. “Organic reach,” “evergreen content,” “share of voice”… they’re said as if everyone has the exact same definition burned into their brain.

This article is an attempt to fix that. It’s not an exhaustive glossary (that’s what Welov’s Social Media Dictionary is for). Think of it as a commented guide to the concepts that get misunderstood the most, blended together the most, or used without anyone actually measuring them.

Metrics: the vocabulary that gets confusing fastest

Reach vs. impressions. Reach is the number of unique accounts that saw your content. Not how many times it was seen; how many different people saw it. Impressions is the total number of times your content was shown, including repeats. One user who sees your post three times generates three impressions but only one reach.

That sounds like a minor distinction. It’s not. A post with high reach and low impressions per user can suggest content that’s seen but not memorable (or not resurfaced). A post with a high impressions-to-reach ratio suggests the same person is seeing it multiple times, or the algorithm is redistributing it across repeated feed views.

Engagement rate is the most cited metric (and the vaguest). It can be calculated on reach, impressions, followers, or a manually defined universe. Before you compare your engagement rate to competitors or to industry benchmarks, make sure you’re using the same denominator. Two common versions:

• Engagement rate by reach = (interactions / reach) × 100. Usually more representative of content quality.
• Engagement rate by followers = (interactions / followers) × 100. Often better for competitive comparisons, as long as you’re intentional about using it.

Share of voice (SOV) measures what percentage of the conversation about a topic or category belongs to your brand. If, in conversations about “sunscreen,” 12% mention your brand and the rest mention competitors, your SOV is 12%. This requires social listening, it’s not something you get from your own post analytics alone. That said, people sometimes extend the idea beyond mentions and use SOV more broadly as: “what % of total category interactions belongs to my brand?”
Just be explicit about which definition you’re using.

Sentiment isn’t a single clean metric, and it’s not binary (positive/negative). Done well, sentiment analysis distinguishes multiple categories and still requires ongoing interpretation, especially because heavy sarcasm on social platforms can absolutely confuse automated models.

Content types in social media

Organic content is what you publish without direct paid media spend behind it. It doesn’t mean “free.” It has production costs, management time, and in platforms with low organic reach, it can require a lot of work for modest results.

Paid content includes ads, boosted posts, and sponsored content. The line between boosting and running a campaign matters: a boost distributes an existing piece of content to more people; a campaign can include custom creatives, advanced targeting, and objectives beyond engagement.

Evergreen content stays relevant over time. A guide on how to write a strong Instagram headline has a long shelf life. A post about a feature launch nobody remembers a month later… doesn’t.

UGC (User Generated Content) is content created by users or customers, not by the brand. It tends to have high perceived credibility and low production cost, but it requires management: permissions, curation, and a system to spot and organize it when it comes in.

Social selling is using social platforms to support the sales process, especially in B2B. It’s not “selling directly on social.” It’s building relationships, sharing value, and creating trust so commercial conversations are easier to start and easier to win.

Content strategy vs. editorial calendar: what’s the difference?

A content strategy defines what you publish, for whom, and why. An editorial calendar defines when, where, and in what format.

They’re complementary, not interchangeable. Having a full calendar is not the same thing as having a strategy.

And if we’re talking strategy, the classic funnel phases still matter:

Most brands overproduce awareness and forget the rest.

Viral, community, storytelling: what these words really mean

There’s a subset of social media vocabulary that has taken on a life of its own, regardless of what it actually measures.

• Viral: used to describe anything from a post with 500 interactions to something that reaches millions. Without a scale reference, the word means nothing
• Community: used to describe both passive followers and active groups with shared identity. Those are not the same thing. Having 50,000 followers isn’t the same as having a community.
• Storytelling: often used as a synonym for “writing in a more interesting way.” The original concept had structure (arc, conflict, resolution) that tends to get lost.‍
• Authenticity: probably the most overused word in the industry. Every brand claims to want it; few define what it means for them.

When concepts get emptied of meaning, strategic conversations get harder. Agreeing on what you measure, what you’re aiming for, and what you call things is part of the job.

Social media dictionary: where to find every term

Social media vocabulary grows every year: new formats, new platforms, new metrics. Some terms are born inside a single platform and migrate elsewhere with slightly different meanings.

Welov’s Social Media Dictionary collects 100+ terms from A to Z, built specifically for in-house Social Media Managers, with definitions that matter in real work contexts.

If you manage social for a company and sometimes feel like the industry speaks in code, it’s a useful resource.

FAQs about common social media terms

What’s the difference between reach and impressions?

Reach counts unique users who saw a post. Impressions count total times the post was shown, including multiple views by the same user. For content quality, reach is often more informative; for distribution patterns, the impressions/reach ratio adds context.

What does engagement rate mean and how do you calculate it?

Engagement rate is the percentage of interactions (likes, comments, shares, saves) relative to a reference universe. You can calculate it by reach, followers, or impressions. There’s no universal formula, the key is consistency and stating the denominator when comparing performance.

What is share of voice on social media?

Share of voice (SOV) measures what percentage of the total category conversation mentions a specific brand compared to the overall volume of mentions in the sector. It’s derived from social listening and indicates your relative presence versus competitors.
