The Danger of Optimizing for the Wrong Question | Brand Building Metrics

As part of our ongoing series on growth and measurement for CPG brands, we’re unpacking how measurement shapes strategy, often in ways teams do not fully realize.
If you missed our earlier posts on defining growth we recommend starting there:
Now let’s talk about something even more subtle.
Sometimes the problem is not the metric.
It is the question behind the metric.
When I worked in television, one of my jobs was to grow our daily audience, particularly for local newscasts. Every weekday morning, our team would assemble with the general manager and review our overnight ratings, we would look at household ratings and share quarter-hour-by-quarter-hour. When the audience dropped off we’d dive into the weeds, assessing blame against any number of reasons. Our metrics were ratings and share and our question was: what happened yesterday and why.
We spent so much time reacting to immediate numbers that we never discussed long-term trends, viable growth tactics, and whether our advertising strategy was supporting brand growth or short term ratings spikes.
I see the same thing happening with CPG brands. The emphasis on ROAS and immediate results has brands asking the wrong question.
Every Metric Is Answering Something

Metrics are not neutral. They are designed to answer specific questions.
ROAS answers: How efficiently did this channel generate measurable conversions?
Velocity answers: How fast does this product move where it is available?
Penetration answers: How many unique households are buying us?
Brand health answers: Are we strengthening memory and future intent?
The issue begins when we optimize aggressively around a metric without revisiting the question it was built to answer.
If the question is too narrow, the optimization will be too narrow.
Optimization Is Powerful and Dangerous
Modern marketing platforms are designed for optimization. Budgets can shift in real time. Creative can rotate automatically. Bids can be adjusted by the hour.
That level of control is impressive.
It also creates a growth trap.
When something improves quickly, it feels like progress. When a number rises in the dashboard, it feels like validation.
But improving a metric is not the same as improving business results.
If we optimize for lowest cost per conversion, we will likely narrow our audience. Here’s where we remind brands that growth comes from growing light buyers which takes broad-reach media.
If we optimize for highest ROAS, we will likely concentrate spend among the most conversion-ready buyers. This also reduces advertising’s reach considerably.
If we optimize for immediate sales lift without regard for margin, we may increase revenue while eroding profitability.
The system will give us exactly what we asked for.
The question is whether we asked the right thing.
Activity Is Not the Same as Outcome
One of the most common missteps we see is confusing measurable activity with meaningful progress.
Impressions increase.
Click-through rates improve.
Conversions rise within a platform.
All of that may be true.
But are we reaching new households?
Are we strengthening long-term demand?
Are we protecting pricing power?
Those outcomes do not always move in tandem with platform metrics.
When activity becomes the goal, strategy narrows around what is easy to measure rather than what matters most.
Short-Term Questions Create Short-Term Strategies
If leadership asks, “What is our ROAS this week?” teams will optimize for this week. (Or even DAY in the case of some brands!)
If leadership asks, “Did this campaign drive incremental sales?” teams will design experiments.
If leadership asks, “Is our buyer base expanding?” teams will look at penetration and reach.
The questions shape the behavior.
When the dominant question is short-term efficiency, marketing naturally tilts toward lower-funnel tactics. Over time, that can create a performance plateau where additional spend produces diminishing returns because the audience pool is not expanding. This is - by far - the most common pitfall in modern media buying.
Nothing is technically broken. The system is simply doing what it was instructed to do.
How to Pressure-Test the Brand Building Metric Question

Before aggressively optimizing any brand building metric, it helps to pause and ask three clarifying questions:
What business objective does this metric represent?
What does this metric not capture?
If we improve this metric dramatically, what might we unintentionally neglect?
This does not mean abandoning performance metrics. It means placing them in context.
Strong brands do not stop optimizing. They optimize within a framework that balances short-term efficiency with long-term expansion.
Strategy Should Lead Measurement
Measurement is meant to inform strategy, not replace it.
When optimization becomes the strategy, decision-making shrinks to whatever is easiest to quantify.
When strategy defines the objective clearly, measurement becomes a tool that supports that direction.
The danger is not that optimization exists. The danger is optimizing for a question that is too small for the business you are trying to build.
So ask yourself: What question or questions are you trying to answer with your metrics?
