Les Binet's recent IPA research dropped a bomb on the marketing world: budget is eight times more important than ROI when it comes to driving effectiveness. Yet 65% of senior marketers still believe ROI is the critical factor. This disconnect isn't just a curiosity, it's a warning sign of what the IPA calls a "death spiral" of shrinking budgets, campaigns and profits.

The problem isn't that marketers rely on metrics. It's that they're optimising for the wrong ones. 

Why your dashboard is lying to you

Your marketing dashboard shows green numbers across the board. High click-through rates. Impressive engagement metrics. ROI that looks healthy on paper. But are you actually growing?

Most dashboards are designed to make you feel good, not think hard. They prioritise efficiency ratios over growth metrics, measuring what's easy to track rather than what actually matters. The result? You end up with a clear view of the wrong destination.

High ROI, low impact: the most dangerous metric in marketing

Here's why ROI is such a terrible metric: it gives you no sensible guidance on whether you should be spending more or less.

Consider a standard media response curve. As you increase spending, you see diminishing returns – that's normal. Revenue continues to climb, but at a slower rate. ROI, meanwhile, declines steadily from the moment you start spending. But here's the critical insight: profit (incremental revenue minus costs) rises to a peak before eventually declining. That peak is where you should be investing – it's where you maximise actual cash in the bank.

The problem? At the profit-maximising point, your ROI has already been declining for some time. If you're chasing ROI improvement, you'll instinctively pull back investment – exactly the wrong move. You might hit an impressive 3:1 return, but you're leaving millions in profit on the table. ROI tells you nothing about whether you're overspending or underspending. It's a metric that actively misleads.

You can't shrink your way to growth

The IPA research reveals that over half of marketers are now targeting sub-segments rather than broad audiences and 62% aren't even targeting over-45s, despite that group controlling 50% of consumer spending. This isn't strategic precision. It's fear disguised as optimisation, driven by misinterpreting what the numbers are actually telling you.

When you focus on the wrong metrics, you make the wrong decisions. You cut budgets to protect ROI ratios. You narrow targeting to improve efficiency. You sacrifice scale for the comfort of impressive-looking percentages. And your profit shrinks as a result.

It's not about more data. It's about smarter questions

At ToolUp, we help brands focus on metrics that actually drive growth, like profit, market share and long-term brand equity, rather than efficiency ratios that create the illusion of performance.

Many marketers are drowning in an ocean of data; dashboards full of numbers that create confusion rather than clarity. That's where ToolUp comes in. Our campaign evaluation services help you identify which metrics genuinely predict business outcomes versus which just look impressive in reports. Through predictive analysis, we model the profit impact of different investment scenarios, helping you find that optimal point on the response curve where you're maximising actual returns, not just ratios. And our consumer understanding work ensures you're reaching the audiences that matter most to your growth, not just the ones that are easiest to convert.

The result? More informed, insightful decision-making that focuses on growing profit, not just protecting percentages. Because the most important question isn't "What's our ROI?”, it's "Are we investing at the level that maximises our actual profit?"
