When a batch of ads comes back unusable, the instinct is to blame the designer or the creator. More often, the problem started with the brief. "Make some ads for the new hoodie, fun and on-brand" leaves every important decision to the person with the least context.
A good brief isn't long. It's specific. It tells the creative team what the ad needs to do, who it's for, what to say, how to prove it and where the click goes. Everything else is execution, which is the part they're good at.
What a creative brief should include
- Objective. What the ad is meant to achieve and how you'll judge it. "Drive first purchases from new customers, judged on cost per purchase" is an objective. "Awareness and sales" is two objectives pulling in different directions.
- Audience and awareness level. Who will see this and how much they already know. Someone who doesn't realize they have the problem needs a different ad from someone comparing your product with two others. Describe the person, not a demographic range: what they're doing now, what bothers them, what they've already tried.
- One angle. The single reason to buy that this ad is built around. One brief, one angle. If you want to test three angles, write three briefs. (If the line between an angle and a variation feels fuzzy, angles vs. variations breaks it down.)
- Key message and proof. The one thing the viewer should take away, plus the evidence that makes it believable: a product detail, a demonstration, a real review, a warranty or return policy. A message without proof is just a claim.
- The offer. What the viewer gets for acting now, if anything. If there's no offer, say so, so nobody invents one.
- Mandatory elements. Logo rules, product shots that must appear, legal lines, disclosure requirements, brand colors and fonts.
- Formats and sizes. Which placements, aspect ratios and lengths you need, and how many versions of each. Platform specs change, so point to the current documentation rather than copying numbers from an old brief.
- References. Ads or styles you like, each with a note on what specifically to take from it. "The pacing of this one" or "how this one uses text over the product" is useful. A link with no explanation isn't.
- Do and don't. Words, claims, imagery and tones to use or avoid. Include anything that's caused problems before.
- The landing page. The exact URL the ad will point to and that page's headline. The ad should set up what the page delivers. If the ad would promise something the page doesn't mention, fix one of them before production starts.

A quick example
Here's how sections 3 to 5 and 11 might read for a fictional insulated bottle brand, Ridgeway. Everything here is hypothetical.
- Angle: For commuters who end up drinking lukewarm coffee at their desk, Ridgeway keeps it hot through the morning because of its double-wall vacuum insulation.
- Key message: Your coffee is still hot when you finally get to it.
- Proof: A simple demonstration of the bottle being opened hours after filling, plus real reviews that mention temperature.
- Landing page headline: "Coffee that's still hot when you get to it."
Notice how little room that leaves for a generic ad. The designer knows who it's for, what to show and what the page will say next.
Common brief failures
- Several angles in one brief. The team tries to fit everything into one ad and you get clutter that says nothing clearly. Or they pick one, and it isn't the one you meant.
- A demographic instead of a person. "Women 25 to 45" doesn't tell a writer what to say. "Runners who've given up on earbuds that keep falling out" does.
- No proof. Without it, the team falls back on adjectives like premium, amazing and best-in-class.
- No landing page. The ad and the page get built separately and end up promising different things. That gap is a common reason for good clicks and poor conversion, and it's why message match belongs in the brief, not just the post-mortem.
- References with no explanation. The team copies the wrong part of the example.
- Missing specs. Ads come back in one size and have to be rebuilt for every other placement.
- Compliance left to chance. If the ad uses reviews, creator content or health-related claims, say so in the brief. Reviews must be real, creator content needs the right usage rights and disclosures, and the FTC's Endorsement Guides apply to testimonials and endorsements. This isn't legal advice, so check with a lawyer for your situation. Creator briefs have their own considerations, covered in how to brief UGC creators.
- Changing the brief mid-production. If the angle changes, write a new brief. Quietly editing the old one leads to ads that match neither version.
- No feedback loop. Share results with the people who made the ads: which angle won, which hook worked. The next brief and the next batch both get better for it.
Review against the brief, not your taste
When the work comes back, judge it against what you asked for. Does it speak to the audience you described? Is the angle clear at a glance? Is the proof visible? Does it set up the landing page?
If the answers are yes, it's ready to test, even if it isn't how you would have done it. The market gets the final say, not the review meeting.
The short version
- A brief should make the strategic decisions so the creative team can focus on execution.
- One brief, one angle, with a clear message and real proof.
- Describe the audience as people in a situation, not a demographic range.
- Always include the landing page the ad will point to.
- Review what comes back against the brief, and share results so the next round improves.
