The single biggest predictor of whether an agency delivers ads that actually convert, static or video, isn't their portfolio, it's your brief. Founders who hand over a vague brief and hope the agency "figures it out" almost always end up with beautifully shot content that doesn't sell, followed by a frustrating round of revisions that still miss the mark — because the underlying problem was never the execution, it was the brief itself.
Why Do Most Briefs Fail to Produce Good Ads?
Most briefs fail because they describe what the video should look like instead of what it needs to accomplish. A brief that says "show the product being used, upbeat music, bright lighting" tells an agency nothing about who's watching, what objection they have, or what would actually make them stop scrolling. The fix is starting every brief with the problem the video needs to solve, not the aesthetic you're imagining — aesthetic decisions should come from the agency once they understand the strategic goal.
What Strategic Context Does an Agency Actually Need?
Four things matter more than anything else: who the audience is and what they currently believe, what specific objection is stopping them from buying, what's already been tested and what happened, and what success looks like in numbers, not adjectives. An agency that knows your CTR is struggling because of trust, not awareness, will make completely different creative choices than one told to "make something that pops."
Brief the Objection, Not the Concept
Instead of briefing a product demo video, brief the specific objection it needs to overcome. "This video needs to address why people think our supplement won't work as fast as the market leader" produces sharper creative than "make a video about how our supplement works." Objection-first briefs force the agency to build persuasion into the structure, not just the visuals.
How Specific Should the Brief Be About Format?
Specific enough to constrain production decisions, loose enough to leave room for creative judgment. Include the platform and placement, since a 9-second hook and a 60-second product demo are structurally different pieces of content, not the same video at different lengths. Include hard requirements, like whether captions are mandatory for sound-off viewing, but avoid dictating exact shot sequences unless you have strong data behind that choice.
If you're testing early-stage messaging, tell the agency this is a test asset, not a hero piece, and greenlight a faster, lower-production format accordingly.
What Reference Material Actually Helps?
Good reference material shows the emotional register you're aiming for, not just visual style. Competitor ads, even ones you don't like, are useful because they show what your audience is already seeing. Past-performing content from your own account, even organic posts, tells the agency what's already resonating with your specific audience rather than a generic one. Avoid sending a moodboard of unrelated brands without explaining what specifically you want pulled from it — "I like this brand's energy" isn't actionable on its own.
Brief for Variants, Not One "Perfect" Video
This is where most founders under-brief. A single brief requesting one finished video sets an agency up to over-invest in polish on a single bet. Instead, brief for a testing framework: request two to four hook variations off the same core concept, so variation gets built into production from the start rather than the first cut being treated as final.
Set Clear Approval and Revision Boundaries
Specify upfront how many rounds of revision are included and what kind of feedback is useful at each round. Feedback like "make it feel more premium" late in the process is expensive and hard to act on. Feedback anchored to the original brief — "this doesn't address the objection we discussed" — keeps revisions focused and prevents scope creep on both sides.
How Do You Brief Static Ads?
A static ad brief works the same way, only tighter: a static has one frame to make its case, so the brief should name the single angle each ad carries, the offer, and the one line of proof that backs it up. Ask for several headline and visual variations of each angle, list the sizes you need (feed, story and carousel), and share your current best-performing static so the agency builds on what already works.
A Simple Brief Structure You Can Reuse
A brief that consistently produces strong performance video covers: the audience and their current belief, the specific objection to address, the platform and length, what's already been tested with results, the number of variants needed, hard requirements like captions, and a clear definition of what success looks like in metrics. Everything else — the shot list, the exact pacing — is better left to the agency's judgment once the strategic brief is solid.
- Objective: what success looks like, in metrics.
- Audience: who they are and what they currently believe.
- Objection: the specific doubt the ad must overcome.
- Offer: what you are asking people to act on.
- Format: platform, placement, sizes or length, and hard requirements like captions.
- References: what has been tested, with results, plus ads whose tone you want.
- Variants: how many hook or headline variations you need.
- Approval: who signs off, and how many revision rounds are included.
