What should a marketing brief include?

A strong brief includes who you are the best choice for, what makes you different, the single goal of the work, the audience it speaks to, the one message you want to land, the brand standards to work within, and how success will be measured. The most important parts are the position and the goal. Without those, the rest is decoration and the agency is left to guess.

Why do marketing engagements fail at the brief stage?

Most engagements fail before any work is made, because the brief asks for output without supplying direction. A brief that says make us a campaign, with no position, audience, or goal, forces the agency to invent the strategy themselves. Even a great agency will then produce something competent that does not fit, and everyone blames the execution when the real gap was the instruction.

Who should write the marketing brief?

The brief should come from the business, not the agency, because it carries the strategy the agency is meant to execute. It can be written by the owner or by a brand leader acting for them, such as a fractional brand partner. If the agency writes its own brief, the work ends up shaped by the agency's assumptions rather than the business's actual position and goals.

How detailed should a brief be?

Detailed enough to remove guesswork, short enough to stay sharp. One or two clear pages that nail the position, audience, single goal, core message, and success measure beats a thirty-page document that buries the direction. The test is whether a capable stranger could read it and know exactly what to make and why. If they could, the brief is doing its job.

How to Brief a Marketing Agency So You Actually Get Results

Where Engagements Quietly Fail

Most agency relationships do not fall apart over a bad deliverable. They fall apart slowly, over months of work that is fine but never quite right, until the owner concludes the agency is not very good. In a lot of those cases, the work was doomed at the start, by a brief that asked for output and supplied almost no direction.

The typical brief sounds something like: we need a new campaign, can you put something together. There is no position, no defined audience, no single goal, no message. Just a request for output and a deadline. From there, no agency can win, because they are being asked to produce the answer to a question that was never stated. This is the practical side of why your agency is usually not the problem. The brief is.

What a Brief Actually Is

A brief is not a task list. It is the transfer of direction from the business to the people executing it. Its whole job is to make sure the agency knows what you know: who you are for, why you are the right choice, and what this particular piece of work is supposed to achieve. Done well, it removes guesswork and lets a skilled team do their best work. Done poorly, it leaves them to fill the gaps with assumptions, and assumptions are where competent work goes to become forgettable.

A brief exists to answer one question for the agency before they start: what are we making, for whom, and why will it work? If your brief does not answer that, the work cannot either.

The Essentials of a Good Brief

You do not need a long document. You need a sharp one. A strong brief, often just a page or two, answers the following clearly:

Position. Who you are the best choice for and what genuinely sets you apart. Everything else hangs off this.
Audience. The specific person the work is speaking to, described well enough that the agency can picture them.
One goal. The single thing this work is meant to achieve. Not five goals. One. More leads, a specific launch, a particular shift in perception.
One message. The single idea you want to land. If the audience remembers only one thing, what should it be?
Brand standards. How the brand looks and sounds, so the output is consistent with everything else a prospect encounters.
Success measure. How you will both know it worked, agreed before the work begins so no one argues about the scoreboard later.

The first and third items, the position and the single goal, carry most of the weight. Get those wrong or leave them blank and no amount of detail elsewhere will save the work. The position itself has to be sound before you can brief from it, which is why it is worth being clear on what brand positioning is and why it comes first.

Where a Brief Should Come From

The brief should originate from the business, not the agency. That sounds obvious, but in practice agencies often end up writing their own brief, because the client cannot supply the direction. When that happens, the work is shaped by the agency's assumptions about your business rather than your actual position and goals, and you have quietly handed your strategy to a vendor.

This is exactly why the order of operations matters so much. You cannot write a good brief without a clear brand direction behind it, which is why so many briefing problems are really positioning problems in disguise. It is also why a clear brief is one of the highest-return things an owner can produce: the same agency, given real direction, often starts delivering work that finally fits. If writing that direction is the part you are stuck on, that is the work a brand leader does before any vendor is hired, and what the Valore process is built to produce.
