How to write a marketing brief for your agency

Define the business objective

Start with the business change you want, then describe the marketing problem standing in the way. “We need more traffic” leaves out why that traffic matters. “We need more inquiries for our maintenance service in the areas we can serve” gives the work a direction.

Record the current situation, the desired outcome and any deadline. If you have a numerical target, explain where it came from. If you do not have a reliable baseline, make establishing one part of the initial work.

Describe the audience and offer

Name the person making the decision, the need that brings them to you and the service or product you want to promote. Include relevant locations, eligibility requirements and situations where your business is not a fit.

Use language from actual customer conversations when you can. Add the questions buyers ask before committing, the alternatives they consider and the evidence you can provide. Separate known customer behavior from your assumptions.

• Who is the offer for, and what triggers their search?
• What does the offer include and exclude?
• What would help someone choose you with confidence?

Explain your starting point

List your website, current campaigns, available content and the tools you use to handle inquiries. Summarize what you have already tried and what happened. Include the period covered by any report and explain what its numbers count.

Note assets that can be reused: brand guidelines, approved photography, useful articles, customer questions and permitted project examples. Identify account owners and access gaps; the brief needs an inventory, not passwords or customer records.

Separate essentials from possibilities

Split requests into work that must happen, work worth exploring and work outside the current project. Explain the reason behind each requirement so the agency can suggest alternatives where appropriate.

For a website project, that might mean improving the service pages and inquiry flow first, while a larger content library follows later. For campaigns, it could mean checking conversion measurement before expanding activity.

If you are unsure which channel fits the problem, say so. Ask for a recommendation with its assumptions, tradeoffs and dependencies rather than selecting a channel merely to complete the brief.

Set budget and timing constraints

State the budget range you can consider and whether it covers agency work, advertising spend, software and other production costs. Separate ongoing monthly costs from one-time project costs.

Explain any firm date and why it matters. Include internal review time, busy periods, asset availability and technical dependencies. A requested launch date is a planning constraint; the delivery schedule still needs to be agreed.

• What is already committed, and what remains flexible?
• Who can approve scope or budget changes?
• What needs to happen before the work can start?

Agree on what progress means

Define the action you care about and what makes it valuable. A submitted form, a qualified inquiry and a new customer are different events. Choose definitions that the people doing the marketing and the people following up can use consistently.

For example, you might define a qualified inquiry as someone requesting an offered service within your service area. Add how inquiries are recorded, who assesses them and which outcomes can be connected to marketing activity. Mark gaps rather than claiming complete attribution.

Use supporting measurements to investigate what needs attention. Agree when to review progress and which decisions the report should inform. Record targets as planning goals and compare them with the agreed baseline.

Name owners and the next decision

Identify one person who can consolidate feedback, the people who approve content and the person responsible for responding to leads. Record who supplies assets and who confirms that factual or technical details are accurate.

End with the decision you want from the first conversation: a recommended scope, an assessment of the current setup, a phased project plan or questions needed to prepare a proposal.
