Traditional marketing won’t cut it anymore.
Today’s audiences live online—scrolling Instagram, swiping TikTok, networking on LinkedIn. If your business isn’t meeting them there with strategy and intent, you’re invisible.

That’s why partnering with a social media marketing agency isn’t just helpful, it’s essential. These agencies help brands build influence, drive engagement, and turn attention into real-world results.

Whether you’re launching a brand or scaling an established one, a strong social presence drives awareness, conversion, and long-term growth.

So, what does a social media marketing agency actually do—and is it worth it? Let’s break it down.

What is a social media marketing agency?

A social media marketing agency is a specialised type of digital marketing agency that focuses exclusively on helping brands grow through platforms like Instagram, Facebook, LinkedIn, TikTok, Pinterest, and YouTube.

Their goal? To build influence, connect with your audience, and convert that attention into measurable growth.

Social media marketing agencies can be thought of as your outsourced social media team: experts in strategy, content, ads, engagement, and analytics — all under one roof.

Why hire a social media marketing agency?

It’s a fair question, and one many business owners ask.

Sure, you can manage your own social media. But hiring a social media marketing agency isn’t just about saving time—it’s about getting better results.

Anyone can post. But driving real growth? That takes strategy, tools, and consistency most in-house teams simply don’t have. Without those, you risk wasting time—or worse, damaging your brand.

Take the Queensland Symphony Orchestra, for example. In an attempt to modernise their promotions, they used an AI-generated image to advertise an upcoming performance. The backlash was harsh. Commenters called out the irony of using artificial content to promote a live artistic experience, and the post missed the mark entirely.

Social media isn’t just about posting. It’s about understanding context, culture, and your audience. That’s what a good agency brings to the table.

So, the benefits of hiring a social media marketing agency go well beyond convenience. You’re tapping into a team of specialists—strategists, designers, copywriters, ad managers, and analysts—who live and breathe social strategy.

They know what’s working on each platform right now, how to navigate algorithm shifts, and how to align content with your brand’s tone, audience, and goals.

Here’s what you gain when you work with an agency:

• Expert insight and platform-specific knowledge: Agencies stay up to date on best practices, algorithm changes, and emerging features across Instagram, TikTok, LinkedIn, and more. That knowledge shapes campaigns that get seen and convert.
  
• Time and resource savings: Instead of spreading your internal team thin, agencies manage the content calendar, design assets, ad campaigns, and reporting — freeing you up to focus on other priorities.
  
• Stronger creative and copywriting: Agencies craft scroll-stopping content that’s both on-brand and optimised for engagement. From sharp captions to polished visuals and trending formats, creative quality directly impacts performance.
  
• Access to professional tools and software: Many agencies use premium analytics platforms, scheduling tools, social listening dashboards, and A/B testing environments that most businesses don’t license individually — giving you sharper insights without the overhead.
  
• Trackable ROI: With clear KPIs, conversion tracking, and data-led strategy tweaks, agencies ensure your spend translates into business results — not just likes.
  

A recent HubSpot survey found that businesses working with social media agencies report a 35% lift in campaign performance on average. That means more reach, better engagement, and stronger returns for the same budget.

In short: A smart agency doesn’t just manage your presence—they turn social media into a scalable growth engine.

Key services provided by a social media marketing agency

Now that you know why you should hire a social media agency, let’s take a look at exactly what a social media marketing agency can do for you.

Developing tailored social media strategies

A smart agency doesn’t just post for the sake of it — they develop social media marketing strategies tailored to your business objectives, audience behaviours, and competitive landscape. This process is known as social media marketing strategy development, and it’s the foundation of any successful campaign.

That means starting with the fundamentals:

• What are your brand goals — awareness, sales, loyalty, or all of the above?
  
• Who is your ideal audience, and how do they engage across platforms?
  
• What’s already working in your niche, and where are the gaps?

Through a mix of customer insight, competitor research, and platform-specific trend analysis, agencies shape a plan that’s not only creative, but intentional. Without it, social media becomes noise—not growth.

Bez in action: How Rapid Tune gained 150+ new customers with a social strategy

Bez Agency worked with Rapid Tune on their social media strategy. At the start, Rapid Tune had no online presence—just a website. This means that Rapid Tune also had no way of showcasing any social proof or developing a personal brand.

Bez Agency started by analysing their foundation before creating a strategy to fine-tune and establish their branding. From there, Bez implemented content creation paired together with social management. The result? An online identity with better brand awareness and increased conversion, generating them new business across the states with over 150 new customers within the first 2 months of the ads activation

Creating and posting engaging content

Social media is fuelled by content, but great content isn’t just aesthetic, it’s strategic. Behind every successful brand presence is a purposeful approach to social media content creation.

As easy as it is to create your own content these days, a skilled agency knows that effective content doesn’t begin in Canva—it begins with clarity. Clarity around your audience, goals, and the kind of value your brand offers.

That’s why a solid content strategy comes first. Every asset—whether it’s a short-form video, carousel post, or branded story—is created to do more than look good. It’s crafted to inform, engage, convert, or build trust.

Agencies handle the end-to-end process: ideation, production, and scheduling. But more importantly, they tailor social media posts to each platform’s nuances.

A post that thrives on Instagram might flop on LinkedIn—so formatting, caption tone, visual layout, and even post timing are all optimised per channel. They also layer in technical best practices like hashtag hierarchies, ALT text, link tracking, and engagement hooks to maximise reach and retention.

Running paid social media advertising campaigns

Organic reach has limits, and in today’s competitive feed, visibility often requires investment. That’s where paid social media advertising comes into play.

Social media agencies manage the full advertising workflow, from campaign setup to creative production and performance optimisation. They handle precise audience targeting, dynamic ad placements, and budget allocation across platforms like Meta, TikTok, LinkedIn, and Pinterest.

Through social media ad campaigns, agencies test multiple versions of creative, messaging, and CTA placements using A/B experiments to find what actually converts—not just what looks good.

Meta’s internal tests found that ads using A/B‑tested creatives delivered 21% lower cost per website conversion—an effective proxy for significantly higher ROI. With the right strategy, paid ads don’t just amplify reach—they increase relevance and results.

Community management and audience engagement

Your audience isn’t just watching, they want to be part of the conversation. And that’s where social media community management becomes essential. If you aren’t engaging with your audience, you’re losing customers.

Agencies go beyond posting; they actively manage replies, DMs, tags, and mentions to make sure your followers feel seen and valued. Whether it’s answering product questions, addressing concerns, or just replying with humour and personality, consistent engagement fosters trust and loyalty.

Many also implement audience engagement strategies like polls, Q&As, giveaways, and comment prompts to spark interaction and improve algorithmic reach.

Being social is about showing up—not just broadcasting.

Influencer marketing partnerships

Influencer collaborations used to be a ‘nice to have’, but now they’re a strategic part of any social strategy. A strong influencer marketing agency will help you navigate the space with intention, ensuring that partnerships are aligned with your audience, product, and values.

Agencies source, vet, and manage influencer partnerships across platforms. They negotiate deliverables, track campaign metrics, and ensure content feels organic—not transactional. From niche nano-influencers to large-scale creators, the goal is always the same: build credibility through trusted, human voices.

According to the Edelman Trust Barometer, 61% of consumers trust influencer recommendations more than branded content. Authenticity matters — and influencer marketing delivers it at scale.

Tracking metrics and analytics

Anyone can post. But measuring what moves the needle? That’s the mark of a professional.

Agencies rely on social media analytics to go beyond vanity metrics and uncover what’s really driving results. Key social media metrics like reach, saves, engagement rate, click-throughs, and conversion paths inform decisions on content, ad spend, and platform focus.

With accurate campaign tracking, agencies can course-correct fast—reallocating resources to high-performing strategies and cutting what’s underwhelming.

In digital, data is direction. And smart tracking turns insight into action. 

How to choose the right social media marketing agency for your business

Choosing the right social media partner can make or break your results. With so many agencies out there, knowing what to look for helps you avoid wasted time, underwhelming performance, and cookie-cutter strategies.

To choose a social media marketing agency that’s the right fit for your brand, go beyond the surface. A flashy Instagram feed or polished pitch deck isn’t enough — what matters is how well they understand your goals, audience, and market landscape.

Here’s what to look for:

• Relevant industry experience: The best social media marketing agency will have a track record in your space—or at least a similar audience segment. They’ll know the tone, tactics, and trends that move your specific market.
  
• Transparent reporting and clear KPIs: Ask how they track success. Do they report on vanity metrics like follower count, or are they focused on meaningful performance indicators like engagement, clicks, conversions, and cost efficiency?
  
• Platform-specific expertise: Each platform behaves differently. TikTok rewards short-form creativity; LinkedIn demands authority and insight. Your agency should tailor strategies per channel—not just copy and paste across platforms.
  
• Defined onboarding and strategy process: The first 30 days should include deep research, competitor analysis, tone development, and strategic planning — not just posting.
  
• In-house creative and copywriting capabilities: High-performing content depends on sharp creative and compelling copy. Make sure the agency can produce it — or has trusted partners who can.
  

Tip: Ask for recent case studies, not just templates. Get them to walk you through their process, from brief to content rollout to optimisation. The best social media marketing agency won’t hesitate to show their work.

Hiring an agency is a partnership. The right one will feel like an extension of your team — not a disconnected vendor.
