A creative brief for ads should fit on one page and lead with the argument. Most of the ones I am shown lead with dimensions, brand colours and a message hierarchy, which specifies the packaging carefully and leaves the actual point to be inferred by whoever is designing.
Get the argument right and a designer can solve the rest. Get it wrong and no amount of constraint specification rescues the advert.
This is for you if your creative comes back correct, on brand, and somehow not compelling.
What belongs at the top of a creative brief for ads
The problem being named, and who is meant to recognise themselves in it.
Not the product. Not the offer. The specific situation somebody is in that makes this relevant, stated precisely enough that the right person feels addressed and the wrong person does not.
Then the outcome being promised, in terms of what life looks like afterwards rather than how the mechanism works.
Those two things are the brief. Everything below them is administration, and if the person designing understands both, most of their decisions become obvious.
The test I apply before sending one: could a designer who has never met this business produce something reasonable from the top third of this page alone. If not, the brief is packaging without content.
The five rules in every creative brief for ads I send
These are design constraints, and they go below the argument rather than above it.
Keep elements to a minimum. Every additional object competes for the same second of attention. Most underperforming creative I see is not badly made, it is crowded.
Minimum text on the creative itself. The image has one job, which is to stop somebody. Text competes with that job, and anything requiring reading belongs in the copy beneath, where a stopped reader will actually read it.
Subtle colours. Saturated colour is one of the fastest signals that something is an advert. Restraint here buys you a moment before the reader categorises what they are looking at.
Give elements room to breathe. Space is not wasted area. It is what makes the one thing you want seen actually get seen.
Do not make it look like an obvious paid advert. The governing rule, and the other four are largely instruments of it.
Why the fifth rule governs the other four
Because everything that reads as advertising gets filtered before it is read.
People scrolling a feed have developed reliable pattern recognition for adverts. Saturated colour, dense text, a visible call to action, a product shot on a coloured background. Those signals get categorised in a fraction of a second and dismissed.
So the four preceding rules are not aesthetic preferences. Each removes one of the signals that triggers the categorisation.
That is also why a beautifully produced advert can underperform a rough one. Production values are themselves a signal, and a polished studio image announces a budget behind it, which announces an advert.
The rough version does not trigger the pattern, so it gets a second look, and a second look is all you were buying.
What a creative brief for ads should not contain
Three things that make briefs long and worse.
Brand guidelines reproduced in full. Those exist elsewhere. Link to them, and specify only the deviations relevant to this piece.
A message hierarchy with five levels. If five things must be communicated, you have not decided what the advert is about, and the designer will make that decision for you by accident.
Detailed execution instructions. Specifying the crop, the layout and the colour placement means you have designed it badly in words and asked somebody to reproduce your design. If you know exactly what it should look like, that is a different job than briefing.
Cutting those three usually takes a four page brief down to one, and the one performs better.
A creative brief for ads should be tight on argument, loose on execution
This is the trade that decides brief quality, and most briefs get it backwards.
Tight constraints with a vague message produces work that satisfies every specification and says nothing. The designer had nothing to solve, so they solved the layout.
A sharp argument with loose constraints produces work that occasionally breaks a guideline and lands. That is a better failure mode, and the guideline breach is easy to fix in a round of revisions.
The scarce input is the argument, not the specification. Your designer cannot invent the reason somebody should care, because they do not have access to your sales calls, your cancellation reasons or your search terms report.
Supply that, and the constraints can be a short list rather than a document.
What to specify about placement
Say where it has to work, not what shape to make it.
An advert needing to survive a square feed placement and a vertical story has a real constraint, and a designer who knows why will solve it better than one handed two sets of dimensions with no explanation.
Specifying the reason also surfaces conflicts early. Sometimes one execution genuinely cannot serve both placements well, and it is cheaper to learn that at brief stage than after two rounds of revision.
The same applies to whether it needs to work without sound. Captioning is worth specifying as a requirement rather than assuming, and there is evidence behind it: Verizon Media and Publicis found 80% of consumers more likely to watch an entire video when captions are available, across 5,616 US consumers.
How the brief changes for video
The argument section does not change. The execution notes do, enough to warrant separation.
Minimum text means something different across four seconds than it does on a static image, because text can appear sequentially rather than all at once.
Room to breathe becomes a pacing question rather than a spatial one. And the do-not-look-like-an-advert rule becomes harder, because production values are more visible in motion.
So keep one brief with a shared argument section and two execution sections. Merging them produces rules that make sense for one format and confuse the other, and the designer resolves that confusion however they prefer.
What to change this week
Three steps.
Take your current brief template and move the argument to the top, above every constraint. That reordering alone changes what comes back.
Then cut anything that restates brand guidelines available elsewhere, and replace it with a link.
Then add the five rules as a short list, and see whether your next round comes back less crowded.
Fund the ad set and read what the algorithm chose is the position underneath, ad angles: where the good ones come from covers producing the argument the brief carries, ad copy formulas covers the copy that sits beneath the creative, ad headlines covers the brevity evidence, and the weekly rhythm I run covers how often you will be sending these. On search the equivalent discipline is asset supply rather than layout, which Google Ads management handles differently. To review what your briefs are actually specifying, book a teardown.
