Ad creative brief template: eight lines, one page, no jargon

Introduction

Bad creative is usually a briefing failure rather than a talent failure. "Make something for Instagram, make it look premium" produces exactly what it deserves.

A brief is not paperwork. It is the decision about what the ad is trying to do, made before anyone opens a design tool — which is the only point at which it is cheap to make.

1. An ad creative brief template needs eight lines and nothing more

Who it is for. What they currently believe or do. The one message. The proof. The action. The format and placement. What must appear. How it will be judged.

Eight lines, one page. Longer briefs get skimmed, and the sections that get skipped are always the ones that mattered.

Everything below is what each line has to contain to be useful.

2. Describe the audience by situation, not demographics

"Women 25 to 45" is not a brief. It tells the designer nothing about what to say.

"Parents who have already decided they need tutoring and are comparing three providers" is a brief. It implies the tone, the objection to address, and the level of explanation needed.

Write the situation the person is in when they see the ad. That is what determines whether it works.

3. State what they currently think

The line most briefs omit, and the one that makes creative sharp.

If the audience believes your category is expensive, the ad has one job. If they believe all providers are identical, it has a different one. If they have never considered the category, a different one again.

An ad has to move someone from a starting position. Without naming that position, the creative is aimed at nobody in particular.

4. One message, chosen and written down

The hardest line to fill honestly, because everything feels essential.

Pick one. Fast response, or lowest price, or specialist expertise, or convenient location. An ad carrying four messages communicates none of them, and asking for four is how that happens.

If the business genuinely has several things to say, that is several ads, tested separately.

5. Supply the proof, do not ask for it

Claims without evidence get ignored, and a designer cannot invent evidence.

Give them the actual material: a number, a review quote with a name, a photograph of real work, a specific guarantee, how many customers you have served.

If the brief cannot supply proof for its one message, that is a finding about the message rather than a gap for someone else to fill.

6. Name the format, placement and constraints

Creative that does not fit where it runs fails for reasons unrelated to its quality.

Specify aspect ratio and dimensions, whether it will be seen with sound off, how much text will be legible at the size it appears, and whether it needs to work as a still if the video does not autoplay.

Also list what must appear — logo, price, dates, legal wording — and what must not: claims you cannot support, stock imagery, phrases that have failed before.

7. Write the judging criteria in the brief

Decide before production how the ad will be assessed, because afterwards everyone judges on taste.

Name the metric and the comparison: cost per enquiry against the current best performer, over a stated test period. Include the stopping condition.

This is also what protects the designer. Without it, good creative that produced results gets replaced because someone senior did not like the colour.

8. Brief variations deliberately

If you are testing, say what is varying and hold everything else still.

Three ads with different hooks and the same offer is a test. Three ads that differ in hook, image, offer and layout is three unrelated ads, and whichever wins teaches you nothing transferable.

Note which single element each variation changes, in the brief, before production starts.

Conclusion

Eight lines: audience by situation, their current belief, one message, the proof, the action, the format and constraints, the mandatories and exclusions, and the judging criteria.

Fill every line before anyone designs anything. Most weak advertising is not badly made — it is made against a brief that never decided what the ad was for.
