Why Most Marketing Budgets Underperform — And What to Do About It.

The ANA’s 2023 analysis of programmatic advertising found something striking: only 36 cents of every dollar entering a demand-side platform effectively reaches the intended consumer. The rest is absorbed by ad-tech transaction costs, lost to fraud, or spent on low-value environments. The total annual waste was estimated at between $20 and $26.8 billion — a figure that had risen 34% in two years.

This is not primarily a technology problem. It is a strategy problem. The budgets are large. The measurement is incomplete. And the decisions being made on the basis of that incomplete measurement are systematically pointing in the wrong direction.

The measurement gap

Nielsen’s 2024 Annual Marketing Report surveyed approximately 2,000 global marketers on their ROI practices. The finding is worth sitting with: 84% described themselves as extremely or very confident in their ROI measurement capabilities. Only 38% said they measure traditional and digital channels together — meaning fewer than four in ten are looking at the full picture they claim confidence in.

This overconfidence-to-measurement gap is one of the most consequential structural problems in modern marketing. Decisions made on partial data optimise for what is visible, not what is true. And what is typically visible — last-click attribution, short-term conversion rates, platform-reported ROAS — systematically flatters performance marketing and undervalues brand investment.

The brand vs. performance imbalance

WARC’s 2024 analysis found that 68.8% of marketing budgets are currently allocated to short-term performance tactics, despite evidence that long-term brand investment delivers 2.5 times higher ROI. CMOs’ own stated ideal allocation is closer to 50:50. The gap between what they believe and what they fund is not a knowledge failure. It is a measurement failure.

Analytic Partners’ ROI Genome analysis — drawing on hundreds of billions in analysed marketing spend across more than 1,000 brands — produced a finding that challenges the current allocation orthodoxy directly: brand messaging outperforms performance messaging 80% of the time. Not in brand-awareness metrics. In business outcomes.

The mechanism is cumulative. Brand investment builds memory structures — the associations, preferences, and recognition patterns that make consumers more likely to choose a brand before they are actively in-market. Performance marketing is highly effective at converting existing demand. The problem is that existing, in-market demand is a small fraction of the total available market. Ehrenberg-Bass research estimates that only around 5% of potential buyers are actively in-market at any given moment. Performance marketing, by design, addresses that 5%. Brand building builds the conditions that expand it.

The operational waste layer

Beyond the brand-performance imbalance, there is a separate layer of waste in how marketing budgets are operationally deployed. Gartner’s 2023 CMO survey found that nearly a third of marketing budgets are spent in pursuit of operational excellence in ways that yield inconsistent ROI. Forrester Consulting research found that marketing and advertising technologies not working together cause 12% of ad budgets worldwide to be wasted through integration failures alone.

Content marketing, the channel most commonly cited as a strategic priority, has its own structural problem. Content Marketing Institute research found that only 49% of B2B marketers report that content marketing directly helped generate sales or revenue. Roughly half of all content investment does not produce a traceable revenue outcome — and among organisations without a documented strategy, the proportion is almost certainly higher.

What high performers do differently

The gap between high-performing marketing organisations and their peers is not primarily a budget gap. Salesforce’s State of Marketing research found that high-performing teams are 8.8 times more likely to have adopted a customer journey strategy as part of their overall business approach. 93% of high performers say their external messaging reflects their corporate values, compared to 70% of underperformers — a 23-point gap in brand coherence that shows up directly in business results.

Gartner’s research on its top-tier “Genius brands” found that these organisations drive 16.5 times more site traffic than peer brands and generate 119% higher engagement rates on social. The differentiator is not ad spend. It is the presence of a governing brand framework that makes every execution decision more coherent. Analytic Partners found that brands adopting measurement programmes and scenario planning achieve a 25–70% increase in ROI — not by spending more, but by spending more accurately.

The strategic conclusion

Most marketing budgets underperform for the same underlying reason: execution without strategy produces activity without direction. The metrics that dominate budget decisions are optimised for short-term visibility, not long-term value. The channels that are easiest to justify are not always the ones with the highest return. And the brand investment that would make everything else more effective is, systematically, the first thing cut.

The fix is not a channel reallocation. It is a sequencing decision. The organisations that generate the highest returns from their marketing budgets are those that build the strategic layer first — positioning, narrative, audience clarity — and then allocate execution budget against a framework that reflects what they actually know. Gartner CMO research from 2024 found that 64% of CMOs say they lack the budget to execute their strategy. That is a real constraint. But it is also, frequently, the result of deploying budget before the strategy exists that would make it work.
