Social Media Managers: What They Can Do and What They Cannot

A social media manager is the person responsible for planning, publishing, and managing a brand’s presence across social platforms. In practice, the role covers content creation, community management, scheduling, reporting, and increasingly paid social, though the boundaries vary considerably depending on the size and structure of the team around them.

The challenge most businesses face is not finding someone to fill the role. It is understanding what the role can realistically deliver, where it sits in the broader marketing structure, and how to measure whether it is working. Get that wrong and you end up with someone producing a lot of content that does very little for the business.

What Does a Social Media Manager Actually Do?

The honest answer is that it depends on the organisation. In a small business, a social media manager might be doing everything from writing copy and designing graphics to running paid campaigns and responding to customer complaints in the comments. In a larger team, the role is more likely to be focused on content planning and publishing, with paid social handled separately by a performance team.

At a functional level, the core responsibilities tend to include: developing a content plan aligned to business objectives, creating or commissioning content, scheduling and publishing across relevant platforms, monitoring performance and adjusting based on what the data shows, managing community interactions, and reporting back to stakeholders on what is working and what is not.

What gets left out of most job descriptions is the judgment required to do the role well. A social media manager is making editorial decisions every day. What to say, how to say it, when to post it, whether to respond to a comment and how. That judgment is harder to hire for than platform knowledge, and it is the thing that separates a competent social media manager from an exceptional one.

If you want a broader grounding in how social fits into a full marketing structure, the social media marketing hub covers strategy, channels, content, and measurement in one place.

Why So Many Social Media Hires Underdeliver

I have seen this pattern repeat across agencies and client-side businesses more times than I can count. A business hires a social media manager, gives them access to the accounts, points them at a brief that is either too vague or too prescriptive, and then wonders six months later why nothing has moved.

The problem is rarely the person. It is the setup. Social media managers are frequently hired without a clear answer to a basic question: what is this channel supposed to do for the business? Brand awareness? Lead generation? Customer retention? Community building? The answer shapes everything, from the platforms you prioritise to the content you create to the metrics you track.

When I was building out the team at iProspect, we went through a period of significant growth, from around 20 people to closer to 100 over a few years. One of the things I noticed during that period was how often social media sat in a grey zone between creative and performance. Nobody quite owned the commercial brief for it. The creative team thought it was a distribution channel. The performance team thought it was a brand channel. The social media manager was caught in the middle, producing content that satisfied neither objective particularly well.

The fix was not a new hire. It was clarity. Once we agreed on what social was supposed to do for specific clients, and built measurement frameworks around those objectives rather than vanity metrics, the output improved significantly. The same social media managers who had been producing average work started producing strong work, because they finally had a clear brief to work against.

Buffer has a useful overview of how to structure a social media marketing strategy that is worth reading if you are in the process of setting direction for a social media hire or an existing team.

The Reach Problem Nobody Talks About Honestly

There is a structural issue with organic social media that most businesses either do not understand or choose to ignore. On most major platforms, organic reach for brand accounts is limited by design. The platforms are advertising businesses. They have a commercial incentive to reduce organic reach and charge for distribution. That is not a conspiracy theory. It is how the business model works.

This matters for how you think about a social media manager’s role. If the primary channel for distributing content is organic social, you are working within significant structural constraints. A skilled social media manager can improve performance within those constraints, but they cannot overcome them through effort alone. At some point, you need to either accept the limitations of organic reach or invest in paid distribution to amplify what is working.

Earlier in my career, I made the mistake of over-indexing on lower-funnel performance channels and assuming that organic and content-led activity was not pulling its weight because it was harder to attribute. What I came to understand over time is that reach matters, and not just the reach of people who are already close to buying. A brand that only activates existing intent is not growing. It is harvesting. Growth requires reaching people who do not yet know they need you, and social media, when used well, is one of the few channels that can do that cost-effectively at scale.

That shift in thinking changed how I briefed social media teams and how I evaluated their work. The question stopped being “how much engagement did this post get?” and started being “are we reaching the right people and is the content changing how they think about us?”

The paid social advertising guide from Buffer is a solid reference point for understanding how organic and paid social can be used together rather than treated as separate activities.

What Skills Actually Matter in a Social Media Manager

Platform knowledge is the thing most hiring managers focus on, and it is the thing that matters least in the long run. Platforms change. Algorithms update. Features appear and disappear. A social media manager who built their entire skill set around a specific platform’s mechanics will be out of date within a couple of years.

The skills that compound over time are different. Writing clearly is one. Not copywriting in the agency sense, though that helps, but the ability to say something specific and true in a short space. Most social content fails not because it looks wrong but because it says nothing worth reading.

Audience instinct is another. The ability to understand what a particular group of people cares about, what they find credible, what they share, and what they scroll past. This is not something you can learn from a platform dashboard. It comes from paying attention, spending time in the communities you are trying to reach, and being genuinely curious about people rather than just their behaviour as data points.

Commercial awareness matters more than most job descriptions acknowledge. A social media manager who understands the business model, the competitive context, and the customer experience will make better editorial decisions than one who does not, even if their platform knowledge is identical.

Data literacy is important, but it is frequently misunderstood. The goal is not to be able to pull reports. It is to know what the numbers mean, what they do not tell you, and when to trust them. I have sat in enough reporting meetings where someone has presented a 40% increase in engagement rate without anyone asking whether engagement rate was the right metric to begin with. That kind of uncritical relationship with data is more dangerous than having no data at all.

Copyblogger’s piece on a comprehensive approach to social media marketing makes a useful case for why social media management needs to be connected to broader marketing thinking rather than treated as a standalone discipline.

How to Structure the Role for Different Business Sizes

The right structure for a social media function depends on where the business is and what it needs social to do. There is no universal answer, but there are some useful principles.

For small businesses and early-stage companies, the social media manager is often a generalist. They need to be able to create content, manage community, run basic paid campaigns, and report on performance. The risk at this stage is spreading too thin across too many platforms. Better to do two platforms well than five platforms badly. Platform selection should follow audience concentration, not trend or personal preference.

For mid-size businesses, the role typically needs to split. Content strategy and community management on one side, paid social on the other. These require different skills and different tools, and trying to find one person who does both at a high level is harder than it sounds. It is possible, but it is not the norm.

For larger organisations, social media management tends to become more specialised and more cross-functional. There may be separate people managing different platforms, a creative team producing content, a paid social team managing spend, and a data team handling reporting. The challenge at this scale is coordination. Content, paid, and data need to be pulling in the same direction, and that requires someone with enough seniority and commercial understanding to hold the brief together.

Mailchimp’s overview of social media strategy covers the planning frameworks that apply at different stages of business growth, which is useful context if you are thinking about how to structure the function.

Tools and Technology: Useful, Not significant

There is no shortage of tools available to social media managers. Scheduling platforms, analytics dashboards, content management systems, AI writing assistants, social listening tools. The market is well-served and the options are good.

What I would caution against is the assumption that better tools produce better results. They do not. Tools reduce friction and save time. They help a good social media manager work more efficiently. They do not compensate for weak strategy, poor content, or unclear objectives.

The tools worth investing in are the ones that give you better signal on what is working. Scheduling tools are a convenience. Analytics tools that help you understand audience behaviour and content performance are genuinely valuable. Social listening tools that surface what your audience is talking about beyond your own channels can inform content strategy in ways that internal data alone cannot.

AI is changing what is possible in content production. The volume of content a small team can produce has increased significantly with AI-assisted writing and image generation. But volume is not the problem most social media functions have. Relevance and quality are. More content produced faster is only an improvement if the content was already good. If it was not, AI just accelerates the production of things people scroll past.

How to Measure a Social Media Manager’s Performance

This is where most businesses get it wrong, and it is worth spending some time on because the measurement framework you use shapes the behaviour you get.

Follower count is a vanity metric. It tells you about historical accumulation, not current performance. A brand with 200,000 followers and 0.1% engagement rate is reaching fewer people per post than a brand with 10,000 followers and 4% engagement rate. The number on the profile is almost meaningless as a performance indicator.

Engagement rate is better, but it is still a proxy. What you really want to know is whether the content is reaching the right people and whether it is changing anything, whether that is brand perception, website visits, enquiries, or purchases. Engagement is a signal that content is resonating, but it is not a business outcome in itself.

The most useful measurement frameworks tie social media activity to business outcomes through a combination of direct attribution, where it is possible and honest, and broader indicators like brand search volume, direct traffic, and customer feedback. I say honest attribution because social media’s contribution to awareness and consideration is frequently undervalued in last-click models. That does not mean you should not try to measure it. It means you should be realistic about what the numbers are telling you.

When I was judging at the Effie Awards, the entries that stood out were not the ones with the most impressive engagement numbers. They were the ones where the team could clearly articulate what the work was supposed to do for the business, and then demonstrate, with appropriate honesty about the limits of measurement, that it had done it. That clarity of objective and measurement is what separates marketing that matters from marketing that is just activity.

Semrush has a thorough overview of social media marketing strategies that covers measurement frameworks alongside channel strategy, which is useful if you are building a reporting structure from scratch.

The Relationship Between Social Media Managers and the Broader Marketing Team

Social media does not work well in isolation. It is one channel within a broader marketing mix, and the social media manager’s output should be informed by and connected to what is happening across the rest of the business.

In practice, this means the social media manager needs access to the marketing strategy, not just a content brief. They need to understand what campaigns are running, what the business is trying to achieve in the next quarter, what the sales team is hearing from customers, and what the product team is building. That context shapes what good social content looks like.

The social media manager also needs a feedback loop back into the organisation. What they see in the comments, in the DMs, in the way people respond to different types of content, is genuinely useful intelligence. It is qualitative and anecdotal, but it is real-time and often ahead of what shows up in formal research. Businesses that treat social media as a one-way broadcast channel miss this entirely.

I remember early in my career sitting in a brainstorm where the brief had been written entirely from the inside out. What the brand wanted to say, not what the audience wanted to hear. The social media manager in the room was the one who kept pulling the conversation back to what she was actually seeing in the comments and messages. She was right, and the work was better for it. That kind of ground-level audience intelligence is one of the most underused assets in most marketing teams.

For a broader perspective on how social media fits into the full marketing picture, the social media marketing section covers strategy, channels, and measurement in more depth.

What to Look for When Hiring a Social Media Manager

Most job descriptions for social media managers are a list of platform names and tools. That is not a useful hiring filter. Here is what actually matters.

Ask them to show you content they have created that they are proud of, and then ask them why it worked. You are not just evaluating the content. You are evaluating how they think about it. Can they articulate what the objective was, who the audience was, why they made the choices they made, and what the result was? If they can do that clearly, they have the analytical foundation to improve over time.

Ask them about a piece of content that did not work and what they learned from it. This tells you more than the success stories. Social media involves a lot of failure and iteration. You want someone who treats that as information rather than a source of anxiety.

Ask them how they stay current with platform changes and audience behaviour. The answer should involve genuine curiosity, not just following marketing newsletters. The best social media managers are genuinely interested in people and culture, not just in marketing as a profession.

Ask them what they would need from the business to do their best work. This question surfaces how they think about the role and whether they understand the structural requirements for success. Someone who asks for clear objectives, access to the broader marketing strategy, and a feedback loop with sales or customer service understands the job. Someone who asks for a better scheduling tool probably does not.
