Most disappointing ad creative traces back to a vague brief. Whether the brief goes to a designer, an agency or an AI tool, the output can only be as sharp as the instructions. A good brief is short, specific, and makes the decisions so the creative team does not have to guess.
What a creative brief is for
A creative brief aligns everyone on four things before any work starts: what the ad should achieve, who it is for, what it should say and what it must (and must not) look like. It also gives you a shared standard to review against, which cuts rounds of revision.
The sections to include
1. Objective. The single outcome the ad is meant to drive: purchases, qualified leads, app installs, a webinar signup. One objective per brief. If you list five, the ad will do none of them well.
2. Audience. Who sees this? Go beyond demographics: what problem are they trying to solve, what do they already believe, what objections do they have? "Busy parents who want fast healthy dinners and distrust meal kits as expensive" is usable. "Women 25 to 45" is not.
3. The single main message. The one thing the viewer should take away. If you could only say one sentence, this is it. Everything else is support.
4. Proof. Why should anyone believe it? Reviews, results, numbers you can substantiate, awards, guarantees. Do not use claims you cannot back up.
5. Offer and call to action. What are they being asked to do, and what do they get? Include any price, discount, deadline or free trial, with exact terms.
6. Tone and brand guidelines. Voice, colors, fonts, logo usage, and words to avoid. Link to the brand guide rather than summarizing it.
7. Platforms and formats. Where will this run (Meta feed, Reels, TikTok, YouTube, LinkedIn, Google Display), and in which aspect ratios and lengths? Each placement has its own conventions.
8. Mandatory elements and restrictions. Legal disclaimers, required logos, regulated-industry rules, competitor mentions to avoid.
9. References. Two or three examples of ads you like and one you do not, with a sentence on why. Examples communicate faster than adjectives.
10. Success metrics. The numbers you will judge it by, such as click-through rate, cost per acquisition or ROAS, and the timeframe.

Common mistakes
- •Briefing several goals at once. Split them into separate briefs.
- •Describing the product instead of the viewer. Ads work when they speak to a problem the viewer already has.
- •Leaving out the offer details. Missing terms create last-minute rework.
- •Skipping the proof. Claims without evidence get scrolled past.
- •One brief for every platform. Keep one core message but note how it should adapt per placement.
Briefing AI tools
The same brief works for generative tools, and it helps even more there, because a tool cannot read the room. Detailed audience, message and brand guidance produce usable first drafts instead of generic ones. In Omneky you can supply a brief and your brand guidelines once and generate image, video and copy variants sized for each platform, so you can test several angles of the same brief instead of debating one.
Key takeaways
- •One objective, one audience, one main message.
- •Include proof, offer details and brand rules.
- •Add examples; they communicate faster than descriptions.
- •Define in advance how you will judge the result.
