How to write an ad brief AI actually understands
By the Logicive team · Updated 17 August 2026 · 5 min read
The gap between a generic AI ad and one that looks art-directed is usually not the model. It is the brief. The good news: writing a strong brief is a learnable habit with about four rules, and none of them require knowing anything technical.
The short version
- Describe the scene, not the quality: a place, a light, one focal idea.
- Concrete nouns beat adjectives. "Wet slate" works; "premium vibes" does not.
- One brief, one scene. Ask for variations instead of cramming alternatives into a sentence.
- Keep a never-say list so house rules survive every brief.
Say where, not how good
The most common brief on earth is some version of "professional, high quality, 4K, trending". Every word of it is wasted, because quality is the default rather than a request. Asking for professional is like asking a photographer to use a camera. The model needs the things it cannot guess: where the product is, what the light is doing, and which single idea the eye should land on.
A useful test before you press generate: could somebody build this scene in a real room from your sentence alone? "Premium and eye-catching" fails it, because nobody knows what to buy or where to stand. "The bottle on a bathroom shelf, morning light through frosted glass, one towel out of focus behind it" passes, because it is a shopping list and a lighting plan.
A brief is a location scout's note, not a review of the ad you hope to get. Describe the room, not your reaction to it.
Concrete nouns are the whole game
Adjectives describe your feelings; nouns describe a photograph. "Cozy" could be anything. "A wool blanket, a mug, low lamplight" is a scene someone can build. When a result comes back generic, find the abstraction in your brief and replace it with something you could physically point a camera at.
- Weak: "luxury watch ad, elegant, premium". Strong: "the watch on dark marble, one beam of warm light, dust motes in the air".
- Weak: "fresh and clean skincare vibes". Strong: "the serum bottle on wet slate, morning sun, water beading on the glass".
- Weak: "food ad that makes people hungry". Strong: "the burger mid-assembly, steam rising, sesame bun catching the light".
One scene per brief
Cramming alternatives into one sentence ("on a beach or maybe a kitchen, day or night") forces the model to average them, and averages are mush. You get a beach that is somehow indoors, lit at an hour that does not exist. Decide the scene, write it, and generate. Want to explore? Run the brief, then run a different brief.
The same applies to the number of ideas in a frame. A brief that asks for the product, a model holding it, a lifestyle backdrop, a discount badge and a logo lockup is asking for five focal points, and a frame with five focal points has none. Name the one thing the eye should land on and let everything else serve it.
This is the habit that separates people who get good results from people who conclude the tool is bad. Variations are cheap now. Muddled briefs never were.
Borrow structure from ads that already work
You do not have to invent the concept. The fastest path to a strong ad is often rebuilding a proven structure around your own product: the composition and the hook of an ad that already performs, with your product and brand in place of theirs. Logicive keeps a library of winning ads for exactly this, but the habit works by hand too.
What you are borrowing is structure, not likeness. Name what makes the ad work in words you could hand to someone else: the product is held rather than placed, the light comes from one side, the first line asks a question, the background is a real room instead of a studio. Those are the parts that transfer. Copying the colours, the typeface or the model does not transfer; it just makes a worse version of somebody else's ad, and if the brand is recognisable it borrows their legal problems too.
Write the rules once, not per brief
Anything you find yourself repeating belongs in a standing rule, not in every brief: "always show the label", "never show competitor logos", "never promise results". In Logicive these live in the brand file and apply automatically; elsewhere, keep the list pinned above your keyboard. A brief should carry the scene. The rules should already be there when it arrives.
The rules that matter most are the ones about claims, because those are the ones with consequences outside your ad account. A generated line like "clears acne in seven days" is a health claim you now have to substantiate, and the FTC endorsement guides are equally blunt about invented testimonials. Writing "never promise results, never imply a customer said this" once is cheaper than discovering the alternative.
A strong brief is one sentence about a real place with your product in it. Everything else is a setting the tool already knows.
Questions people ask next
How long should an AI ad brief be?
One sentence is usually right: a place, a light and one focal idea, with the product named. Briefs get worse as they get longer, because every extra clause is another thing for the model to average. If a brief runs past two sentences, it is normally two briefs wearing a coat.
Why do my AI ads look generic?
Almost always because the brief describes quality instead of a scene. Words like professional, premium and high quality ask for the default, so you get the default. Replace every adjective with something you could point a camera at, and the same tool starts producing art-directed work.
Why do the same words give different results each time?
Because generation is probabilistic, not deterministic: the same brief run twice explores two different points in the same space. That is a feature for advertising, where you want a set to choose from rather than one answer. It is also why the working method is generate several and keep one, and why a brief that only works occasionally is a brief that needs to be more specific.
Should I mention camera settings or lenses?
Only if you actually want that look and know what it does. Naming a lens or an aperture is a scene decision, like naming the light. Listing technical words you do not mean, in the hope they read as quality, is the same mistake as writing "4K, professional, trending".
How specific is too specific?
A brief becomes too specific when it starts describing pixels rather than a scene: exact hex values, precise crop percentages, the position of every object. At that point you are art-directing through a keyhole, and it is faster to generate a scene you like and then edit it. The useful ceiling is about one place, one light, one focal idea and your house rules.
Does Google penalise AI-generated content?
No. Google has stated plainly that its focus is the quality of content, not how it was produced, and that what it acts against is automation aimed purely at manipulating rankings. For ad creative the question barely arises, because ad platforms judge performance rather than provenance, but they do ask you to disclose AI content that could be mistaken for real footage.
