Most paid media campaigns underperform before a single euro is spent. The brief — or the absence of one — is almost always the reason. At Choco Media, we’ve seen the same pattern repeatedly: a client arrives with a paid media brief that tells an agency what to buy (Meta, Google, €5,000/month) without explaining what they’re actually trying to achieve. The agency runs campaigns. Results are mediocre. Everyone is vaguely disappointed. The paid media brief you hand over sets the ceiling on what any agency can do for you.
This post is for marketing managers, founders, and in-house teams who are about to hire a paid media agency — or who have been running one and wonder why results feel flat. The 8 questions below won’t guarantee strong performance, but they will eliminate the most common sources of wasted budget before the campaign launches. We’ll also explain what a useful answer looks like versus a red flag, so you can evaluate what comes back.
If you’ve already hired an agency and things aren’t working, this checklist doubles as a diagnostic. Bring these questions to your next review meeting.
Why most paid media briefs fail at the brief stage
A paid media brief is a transfer of context. Your agency doesn’t know your customers, your margins, your sales cycle, or what happened in the last three campaigns. Without that context, they’re guessing — and in paid media, guessing is expensive.
The briefs we see most often are one of two types. The first is a single paragraph: “We want to drive leads for our B2B SaaS product on LinkedIn and Google. Budget is €8,000/month.” The second is a dense PDF that covers brand history, tone of voice, and target personas in detail — but says nothing about what a lead is worth or what the sales team does with it.
- Too little context means the agency picks objectives based on platform defaults, not your business model.
- Too much unfocused context buries the signal in noise — a 40-page brand document doesn’t tell an agency whether to optimise for volume or quality leads.
- Missing commercial data (margins, LTV, close rates) makes it impossible to set meaningful performance targets.
- No historical baseline means early campaigns become expensive research the client is paying for twice.
A good brief is specific, commercial, and honest about what you don’t know. Here’s how to build one.
Question 1: What does a conversion actually mean for your business?
This sounds obvious. It isn’t. “A conversion” means different things across different funnels, and the answer changes how an agency configures tracking, optimisation signals, and success metrics.
What to include in your answer
- The primary conversion event (form fill, booked call, purchase, free trial signup)
- Whether that event is tracked as a pixel event, server-side, via CRM webhook, or not at all
- The downstream conversion that actually matters (form fill → booked call → closed deal)
- Approximate close rate at each stage, even if it’s a rough estimate
If your paid media agency is optimising for form fills but 80% of your form fills are spam or unqualified, you’re teaching the algorithm to find more spam. The agency needs to know this so they can either push the optimisation event downstream (towards booked calls, for example) or filter traffic upstream through tighter targeting.
The question isn’t “what does Meta count as a conversion?” — it’s “what does your finance team count as revenue?” Brief your agency toward the latter, not the former.
Question 2: What is a customer worth to you?
Customer lifetime value (LTV) and average order value (AOV) are the numbers that turn campaign data into business decisions. Without them, there’s no rational basis for evaluating whether a €45 cost-per-lead is good or catastrophic.
The calculation your agency needs
- Average order value or first-purchase revenue
- Estimated LTV over 12 months (or however long your average customer stays)
- Gross margin on that revenue (not top-line)
- Maximum acceptable customer acquisition cost (CAC) — the number at which you’re still profitable
If you don’t know your LTV, give a conservative estimate and flag it as an estimate. An agency working with a rough LTV of €400 will make fundamentally different bid and budget decisions than one working with €4,000 — even if the actual number turns out to be somewhere in between. Silence on this question usually means the agency defaults to minimising cost-per-click, which is rarely what you actually want.
This is one area where working with a paid media partner who asks these questions upfront — rather than optimising for platform metrics — makes a measurable difference to returns.
Question 3: What have you already tested, and what did you learn?
Historical data is the most underused asset in a paid media brief. If you’ve run campaigns before, share everything: what you spent, where you spent it, what the results were, and — crucially — what you concluded from those results.
What useful historical context looks like
- Previous campaign data exports from Meta Ads Manager, Google Ads, or wherever you ran
- A plain-language summary of what you tried (audiences, creative formats, offers)
- What worked, even partially — which campaigns beat your expectations and why you think they did
- What failed — and whether you know why
- Any creative assets (ad copy, video, images) that performed above average
Most clients undersell this. “We ran some Meta ads last year and it wasn’t great” is much less useful than “we ran a lead gen campaign to a lookalike of our buyer list, CPL was €120, our target was €60, and we suspect the landing page was the problem because our click-through was fine.” The second version saves weeks of re-testing what you already know.
Question 4: Who exactly are you trying to reach — and who are you trying to exclude?
Audience definition in a paid media brief is frequently done at the wrong level of abstraction. “Marketing managers at mid-sized B2B companies” describes a demographic. It doesn’t describe a person making a decision, the moment they’re in when they’re receptive to your message, or the adjacent audiences you actively don’t want to pay to reach.
How to brief audience properly
- Describe your best current customer: the role, the company size, the industry, and — if you know it — what triggered their search for a solution like yours
- Specify any audiences to exclude (existing customers, job seekers, countries you can’t serve)
- Flag any audiences you’ve already exhausted or that underperformed in prior campaigns
- If you have first-party data (a customer list, a subscriber list), say so — this changes targeting strategy significantly
First-party data is increasingly the foundation of effective paid media. AI-assisted audience segmentation can make that data go further, but the agency needs to know what you have before they can use it.
Question 5: What does your creative pipeline look like?
Creative is the largest variable in paid media performance. It accounts for more of the variance in results than targeting, bidding, or platform choice — particularly on Meta and TikTok. Many clients brief an agency on media buying without saying anything about where the creative will come from, who approves it, and how fast the iteration cycle can move.
Brief your creative situation honestly
- What creative assets do you currently have available (video, static images, UGC, testimonials)?
- Is creative production in-scope for the agency, or handled separately?
- How long does internal creative approval take, and who has sign-off authority?
- What’s your appetite for testing unconventional formats (raw UGC, talking-head video, direct-response copy)?
- Are there creative constraints — brand guidelines, legal review requirements, topics you won’t advertise?
An agency that receives three approved static images and is told to “make them work” is operating with one hand tied behind their back. If your creative pipeline is limited, say so — a good agency will either include creative production in their scope or tell you honestly that performance will be constrained until it’s resolved.
Question 6: How is your website and tracking set up?
Paid media sends traffic somewhere. The quality of what happens at the destination — and how accurately it’s measured — determines whether campaigns can optimise and scale. This is the question clients most often skip, and it causes the most downstream problems.
What the agency needs to know
- What CMS and landing page platform you’re using
- Whether the Meta pixel, Google tag, and any other tracking tags are installed and firing correctly
- Whether you have server-side tracking set up, or rely entirely on browser-side pixels
- Whether GA4 is configured and whether events are being captured
- If you have dedicated landing pages for paid traffic, or send campaigns to standard website pages
Broken tracking is invisible until you need the data. In our experience auditing paid accounts, roughly a third of new clients have some form of tracking misconfiguration — missed events, duplicate counts, or conversion windows set to platform defaults that don’t match the actual sales cycle. This is fixable, but it needs to surface in the brief, not six weeks into the campaign.
Question 7: What does success look like at 30, 60, and 90 days?
Paid media has a learning curve. Platforms need data to optimise. Creative needs to be tested. Audiences need to be refined. The first 30 days rarely look like the long-run steady state — but clients and agencies often aren’t aligned on what to expect during that period, which leads to campaigns being killed before they have a chance to perform.
How to frame expectations in the brief
- What’s your acceptable CPL or CPA in month one (when data is thin and CPCs are typically higher)?
- What does a healthy 90-day trajectory look like — are you aiming for volume, efficiency, or both?
- Are there external events that will affect performance (product launches, seasonal demand, sales team capacity constraints)?
- How often do you want to review performance, and in what format?
Aligning on milestones before the campaign starts prevents the conversation from defaulting to “results aren’t good enough” at the 30-day mark — which is almost always too early to conclude anything meaningful about a new campaign. It also gives the agency a framework for recommending when to persist versus when to pivot.
Question 8: What is your decision-making process and who is involved?
This is the operational question. Paid media is iterative — creative needs to be tested and replaced, bids need to be adjusted, budgets need to shift between campaigns. Every one of those changes requires someone to approve something. If that approval process takes two weeks and involves three stakeholders, your agency’s ability to respond to data is fundamentally limited.
What to be transparent about
- Who is the day-to-day contact for the agency, and what are their approval limits?
- What requires escalation, and to whom?
- What’s the expected response time on creative approvals and budget change requests?
- Is there a procurement or legal process for new vendors or contracts?
We’ve seen genuinely strong agency work constrained by a client-side approval loop that took 10 business days to turn around a creative swap. The agency can only move as fast as the relationship allows. Being honest about your internal process isn’t a weakness — it lets the agency structure their workflow around it rather than being surprised by it.
What a good brief produces
A brief built on these 8 questions gives an agency the context to set realistic targets, configure tracking correctly, build creative that speaks to the right person, and evaluate performance against the metrics that actually matter to your business. It also protects you: if an agency receives a complete brief and still produces poor results, the cause is more likely their execution than missing information on your side.
- You get proposals that reflect your actual situation, not templated channel recommendations.
- Onboarding is faster because the agency isn’t spending the first month asking questions you could have answered upfront.
- Performance reviews are cleaner because you agreed on targets before the campaign started.
- Budget waste in the early weeks is lower because creative and tracking are right from the start.
The brief is also a useful filter. An agency that receives a detailed, commercial brief and responds with a generic proposal hasn’t read it carefully. That tells you something important before you’ve signed a contract.
A note on what to keep human
A brief template can be generated with AI in ten minutes. What it can’t replace is the judgment required to fill it in honestly — particularly on the questions where the honest answer is “we don’t know” or “the tracking is broken but we haven’t prioritised fixing it.” Those admissions are valuable precisely because they’re uncomfortable. They surface problems that will cost money later if they stay hidden.
If you’re working with a retainer agency rather than a project-based engagement, the brief isn’t a one-time document — it should be revisited when business conditions change, when you enter a new market, or when performance plateaus. The best agency relationships we’ve been part of treat the brief as a living reference, updated as the client’s situation evolves.
