Confession: We Never Fully Trust the Client Brief

Shhh. Don’t tell anyone.

But at Left Off Madison, we never fully trust the client brief. That probably sounds strange coming from an advertising agency. After all, the brief is supposed to be the starting point for everything— strategy, creative, media, production, and even measurement.

But the truth is simple: if we take the brief at face value, we risk failing our clients. And failure is not an option.

So we challenge it.
We question it.
We pressure-test it.

Not because we distrust our clients. Because our credibility and their growth depends on it.

Why We’re Skeptical

There are two reasons.

First, most companies simply don’t have the internal resources to build a perfect advertising brief.

Unless you’re Procter & Gamble, General Motors, or another global giant, the reality is that research budgets are limited, teams are stretched thin, and briefs are often assembled under pressure. That’s not criticism. It’s reality.

Second, and more importantly, our own survival depends on it. If a campaign fails, no one remembers who wrote the brief. They remember the agency. Which means success or failure lands squarely on us.

We’re not order-takers.
We’re growth partners.

So from the moment a brief arrives, we begin asking hard questions.

The First Thing We Challenge: Goals

The first thing we examine with skeptical eyes are the goals, KPIs, and prior performance benchmarks.

Where did these numbers come from?
Are they based on real historical performance—or are they aspirational?
What’s the gap between reality and ambition?
And does that gap align with what we’ve seen in similar categories?

We also dig into the prior campaigns that produced those results. We analyze:

• Media investment allocation

• Channel mix

• Creative execution

• Tracking and measurement methods

Sometimes the performance numbers are solid. Sometimes they’re not. Sometimes the creative is awful. Sometimes it’s not. Either way, we want to know what’s real before we build the next plan.

The Target Audience: Where Briefs Often Go Wrong

Another place we tend to get a little suspicious is the target audience. Okay, a lot of suspicion. Particularly with smaller and mid-size companies that knowingly don’t have a consumer research department

Why? Primarily because we weren’t part of the research process, but our job is to make the campaign perform.

That means we need to validate the insights.

Were the respondents representative?
Was the methodology sound?
Were there internal biases shaping the conclusions?

Sometimes what’s labeled an “insight” is really just an observation. As strategist Beth Barry once said, “Many so-called insights are simply sights.”

We verify everything using our audience intelligence tools. We analyze:

• Current buyers

• Competitive buyers

• Category users

• Potential new audiences

And occasionally we find something startling.

One client, for example, had a 30-year-old national CPG brand with fewer than 8 million users in a category of nearly 120 million consumers.

Their core customer base was 45+ years old.

Yet the brief instructed us to target 18–34 year-olds.

No explanation. Just… younger sounded better. That’s the moment when we say: “Wait a second.”

Sometimes the Opportunity Is Hiding in Plain Sight

When we dig deeper into audiences, we often uncover white space opportunities.

One client came to us with a difficult problem: their brand competed in a category dominated by giants. Their budget was too small to go head-to-head.

So instead of chasing the same audiences as competitors, we looked for a Blue Ocean opportunity— a shared passion that aligned with the ideal consumer.

We found it. We built the strategy around that passion.

Years later, that audience continues delivering strong ROI and competitors are hesitant to move into the space because the brand now owns that cultural territory.

The Budget Reality Check

Then comes the uncomfortable conversation: budget vs. ambition. Sometimes the math simply doesn’t work.

A few years ago, a client brought us $1 million to promote four national CPG brands for an entire year.

The goal? Increase household penetration across a category with 118 million consumers.

We did the math. National coverage wasn’t feasible.

Instead, we focused the investment on be geo-targeting shoppers near specific retail chains— chains like Publix and Albertsons— using digital platforms like Google, Meta and digital outdoor ads to reach the best prospects before they entered the store.

The results were measurable. By comparing test vs. control retail markets, we demonstrated real sales lift.

With proof in hand, the client was able to justify additional investment.

And Sometimes the Insight Changes Everything

Our 5-C process— a fast-and-furious immersive dive into Customer, Culture, Category, Competition, Company— often uncovers something unexpected. Sometimes it completely reshapes the brief.

One skincare brand came to us confused about slow sales. Their positioning emphasized inclusivity across all skin tones and cultural backgrounds. Their website and advertising strongly reflected that diversity. But our analysis revealed something surprising.

The consumers most interested in the products were women with lighter complexions, largely of Asian and European ancestry.

Women of African and Latinx descent showed far less interest. Not because of the brand, but because of different cultural skincare preferences.

The client initially rejected the finding. It wasn’t the answer they wanted.

But six months later, after sales continued to stall, they revisited the strategy. They adjusted their imagery and messaging to reflect the true audience.

Sales surged. BOO-YAA!

The Point Isn’t to Be Right

It’s to get the outcome right. Our goal isn’t to rewrite every brief. Our goal is to strengthen it.

When we challenge assumptions, validate data, and reframe the strategy alongside our clients, something powerful happens:

The brief becomes better.
The plan becomes sharper.
The campaign performs.
And ultimately, the business grows.

Because If Our Clients Win, We Win

At Left Off Madison, we believe the best agency relationships are built on shared accountability. We’re not here to execute instructions. We’re here to help build success.

Which means questioning things when necessary.
Digging deeper when answers feel incomplete.
And doing everything possible to stack the odds of success in our clients’ favor.

Even if it means quietly admitting something most agencies won’t say out loud. We never fully trust the brief. But we absolutely commit to making it better.
