How to Write a Marketing Brief Your Agency Can Actually Use

A marketing brief is a short document that tells an agency or team what a project needs to achieve, who it's for, what to say, what constraints apply and how success will be measured. It is the starting point for every campaign, website, video or content programme, and it is one of the most underestimated documents in marketing.

Most disappointing agency projects can be traced back to the brief. Not because the agency couldn't do the work, but because the goal was vague, the audience was 'everyone', or the real constraint, a budget limit, a launch date, a sceptical board member, was never written down.

Why the brief matters so much

A clear brief does three things. It forces the business to make decisions before money is spent. It gives the agency a fair chance to propose the right solution, rather than guessing. And it creates a reference point for judging the work later: does this do what the brief asked?

Without a brief, feedback tends to become personal taste ('I don't like the colour'), and projects go through rounds of revisions that cost time and goodwill.

The ten-part brief template

1. Background

Two or three sentences on the business, the product or service, and why this project is happening now.

2. Objective

What should change because of this work? Be specific: more qualified enquiries for a particular service, a launch reaching a defined audience, a website that converts better on mobile. Avoid listing five objectives; choose one main goal and, at most, a secondary one.

3. Audience

Who are you trying to reach? Describe them as people: role or life stage, location, language, what they care about, what they currently believe about your category and what might stop them buying.

4. Key message

If the audience remembers one thing, what should it be? Write it in one sentence. Then list two or three supporting points that make it believable.

5. Proof

What evidence supports the message? Case studies, credentials, reviews, product features, guarantees you can actually honour.

6. Deliverables and channels

What do you think you need: a campaign, landing page, video, social content, ads? Be open to the agency suggesting something different if it serves the objective better.

7. Budget

Share a realistic range, separating production fees from media spend. Agencies can't recommend the right approach without knowing the scale.

8. Timeline

Key dates: launch, approvals, events, seasonal moments such as Ramadan or Q4. Include time for any regulatory approvals that apply to your industry.

9. Constraints and mandatories

Brand guidelines, legal or compliance requirements, languages, things you must or must not say, and anything that has been tried before and didn't work.

10. Success measures

How will you judge the project? Agree on the metrics, how they will be tracked and when you'll review them.

Common briefing mistakes

•     'Our audience is everyone.' Nobody can write for everyone.

•     Too many objectives, so nothing is prioritised.

•     Hiding the budget to 'see what they propose'.

•     Prescribing the solution instead of describing the problem.

•     Leaving out compliance requirements until the work is finished.

•     Too many approvers with no single decision-maker.

The briefing meeting

A written brief works best alongside a conversation. Walk the agency through it, invite questions and listen to how they play it back. If their summary sounds different from what you meant, the brief needs work. Agree who gives feedback, how many rounds are included and the timeline for each stage.

Brief, then let the agency think

The best briefs are clear about the problem and open about the solution. If you've described the objective, audience and constraints well, a good agency may come back with an approach you hadn't considered. Judge it against the brief, not against what you expected.

Questions a good agency should ask you

When you hand over a brief, pay attention to the questions that come back. A thoughtful agency will ask what has worked and failed before, who makes the final decision, how sales or operations will handle the leads, what data you can share, and what would make this project a clear success in your eyes. If an agency asks nothing and jumps straight to a proposal, it may be guessing. Good questions are a sign that the brief is being taken seriously.

Keep the brief alive

A brief shouldn't be filed away after kickoff. Bring it to every review meeting and judge the work against it. If circumstances change, such as a new budget, a moved launch date or a different priority, update the brief and share it, so everyone is working from the same version. When the project ends, add a short note on what was learned. Over time, these briefs become a valuable record of what works for your business.

Frequently Asked Questions

How long should a marketing brief be?

Often one or two pages. Long enough to cover the essentials, short enough that everyone reads it.

Should I share my budget with an agency?

Yes. A realistic range helps the agency recommend an approach that fits, instead of guessing.

Who should write the brief?

The person accountable for the outcome, with input from sales, product and leadership as needed. One person should own it.

What's the difference between a marketing brief and a creative brief?

A marketing brief covers the overall objective, audience and plan. A creative brief focuses on the message and creative direction for a specific piece of work.

Can an agency help write the brief?

Many will. A good agency asks questions that sharpen the brief before proposing a solution.

Should a brief include competitor examples?

Yes, briefly. Note which competitors matter, what they do well and how you want to be different. Avoid asking an agency simply to copy a competitor.
