How do I choose the right social media agency?

Define the outcome and the scope of work, shortlist agencies with experience of similar jobs, run a small paid test brief with two or three of them, meet the actual delivery team, check references and agree a contract that gives you ownership of all accounts and assets, with a clear review point.

What questions should I ask a social media agency?

Ask who will work on your account and for how much time, how they choose platforms, how they measure success and handle attribution, how organic and paid fit together, how approvals and crises work, what you will own at the end, and whether you can speak to current and former clients.

What are red flags when hiring a social media agency?

Watch for guaranteed follower or engagement numbers, reporting based on vanity metrics, senior staff in the pitch but juniors on delivery, accounts held in the agency's name, no curiosity about your customers, identical strategies for every platform, and long lock-in contracts without review points.

Should I hire a social media agency or build an in-house team?

It depends on volume, skills and budget. In-house teams build deep brand knowledge and respond quickly; agencies bring specialist skills, broader experience and flexible capacity. Many businesses combine an in-house lead with agency support for specific capabilities such as paid social or video production.

Who should own social media accounts when working with an agency?

Your organisation should always own social accounts, advertising accounts, business managers, content files and analytics, granting the agency access as needed. This protects your history and data and makes it straightforward to change partners if necessary.

How to Choose a Social Media Agency: A Buyer's Guide

Decide what you are buying

"Social media agency" covers very different businesses. Some are content studios that produce posts and videos. Some manage communities and customer conversations. Some specialise in paid social. Some are strategic partners that set direction and integrate social with the rest of marketing. Hiring one kind when you need another is the most common reason relationships fail.

Before speaking to anyone, write down the job. What outcome should social achieve? Which parts of the work do you need help with: strategy, content, community, paid, creators, reporting? Which will you keep in-house? This brief is the yardstick for every conversation that follows.

The cheapest agency is the one that tells you what not to post.

The selection process

An illustrative selection timeline

Allow enough time to see how agencies think, not just how they present. Rushed selections usually choose the best pitch rather than the best partner.

Building the shortlist

Look for agencies that have solved problems like yours: similar audience, similar sales cycle, similar platforms. Industry experience helps but is less important than experience of the job. An agency that has built B2B founder programmes is more relevant to a B2B services firm than one that has run consumer campaigns in the same industry.

Review their own social presence, but do not over-weight it. Agencies busy with client work often neglect their own channels. Look instead at work they can show you, the thinking in their published content and how they talk about measurement.

Test thinking, not presentations

Traditional pitches reward presentation skills and speculative creative made without real knowledge of your business. A better approach is a small, paid test brief: a real but contained problem, such as reviewing your current presence and recommending three changes, or developing one content series. Pay for it. Free pitch work tends to be shallow, and paying signals that you value the thinking.

Watch how they work as much as what they produce. Do they ask good questions? Do they challenge your assumptions? Do they talk about your customers or about themselves? Do they tell you what not to do? An agency that agrees with everything in your brief is less valuable than one that improves it.

Questions worth asking

Who exactly will work on our account, and how much of their time will we get?
How would you decide which platforms we should not be on?
How do you measure success, and how do you handle the limits of attribution?
How do organic, paid and creator work fit together in your approach?
What does your approval workflow look like, and how fast can it move?
How do you handle a social media crisis out of hours?
What will we own at the end of the relationship: accounts, content, data, ad accounts?
Can we speak to two current clients and one former client?

Warning signs during selection

Structuring the contract

A good contract protects both sides and makes expectations explicit. It should specify scope and deliverables, the team and their time, the reporting cadence and metrics, approval processes and response times, ownership of accounts, content, data and ad accounts, confidentiality, crisis responsibilities, and how either side can end the relationship.

Ownership deserves special attention. Social accounts, advertising accounts, business managers, content files and analytics should be owned by your organisation, with the agency given access. Many businesses have lost years of history because an agency set things up in its own name. Make this non-negotiable.

Making the relationship work

Most agency relationships succeed or fail on the client side as much as the agency side. Give the agency access to customers, sales insight and decision-makers. Approve quickly. Share results from other channels. Hold a monthly review focused on decisions and a quarterly review of strategy and fit. An agency treated as a supplier of posts will behave like one; an agency treated as a partner tends to think like one.

The first 90 days

Plan onboarding deliberately. The first month should be spent on understanding: access, an audit of what exists, interviews with customers and sales, and agreement on the strategy and scorecard. Content production can start early, but the first quarter should be judged on learning and set-up as much as on results. Our social media audit is a good shared starting point.

Are you ready to hire an agency?

Answer before you start conversations.

01Can you state the business outcome social should deliver?
If yes: Use it as the yardstick in every conversation. If no: Define it first, or hire for strategy specifically.
02Do you know which parts of the work you will keep in-house?
If yes: Agencies can scope accurately. If no: Decide, or the scope will drift.
03Do you own all your social and ad accounts today?
If yes: Good. Keep it that way in the new contract. If no: Recover ownership before changing partners.
04Is there a named person internally who will manage the agency?
If yes: Agencies perform better with an engaged client lead. If no: Assign one; agencies cannot substitute for internal ownership.
05Are you prepared to pay for a test brief?
If yes: You will see real thinking before committing. If no: Consider it; free pitches mostly show presentation skills.

Key takeaways

01Define the job and the outcome before talking to any agency.
02Match the type of agency to the work: studio, community, paid or strategic.
03Test thinking with a small paid brief and meet the people who will do the work.
04Insist that your organisation owns every account, asset and data source.
05Choose a fee model that rewards your outcome, and plan the first 90 days.
