We live in a world of dashboards, attribution models, and weekly reports packed with numbers. But when it comes to measuring what’s working, most of it is noise. Here’s what I think should sit at the centre of every agency and client conversation.
Ask most marketing teams what they’re optimising for and you’ll get a range of answers. Traffic. Leads. Conversion rate. Cost per acquisition. Return on ad spend. All of them valid. All of them useful. None of them the point.
The metric that matters is profit. Not revenue. Not volume. Profit.
I know that sounds obvious, but in practice, it gets lost surprisingly quickly. You can drive a 100% increase in sales and watch your margins shrink because the cost of acquiring those customers crept up without anyone noticing. You can hit every KPI on the dashboard and still end the quarter in a worse position than you started.
This isn’t an argument against tracking the other stuff. Traffic quality, conversion rate, cost per acquisition – these all matter, and they’re all useful signals. But they’re signals pointing towards something. That something is profit. When we lose sight of that, we end up optimising the wrong things.
What does profit-first thinking actually change? Quite a lot. It changes how you evaluate channel performance. A channel driving high volume at a thin margin looks very different to one driving lower volume at a healthy margin. It changes how you think about pricing. Small adjustments to price points, tested carefully, can move profit meaningfully without touching acquisition costs at all. It changes how you approach budget allocation; scaling back on expensive channels to protect margin, rather than chasing volume for its own sake.
It also changes the conversation between agency and client. When both sides are anchored to the same commercial outcome, the discussions become sharper. Less debate about which metric to report. More focus on what’s actually moving the business forward.
I’ve seen plenty of agency relationships where everyone is working hard, the reports look good, and the client still isn’t growing in the way they need to. Usually, the problem isn’t effort or capability. It’s that nobody agreed on what success actually looks like at a business level.
Profit is the answer to that. It’s the number that, when the books are balanced at the end of the quarter, tells you honestly whether the work was worth doing.
Start there. Work backwards. Everything else falls into place.
