The Efficiency Obsession Is Killing Brand Building

There is a number that should worry every senior marketer, and it is not a conversion rate or a cost per acquisition. It is the percentage of marketing budgets allocated to brand advertising versus performance advertising—and in 2026, it has tilted further toward performance than at any point in the past thirty years. The IPA Databank, which tracks effectiveness across thousands of campaigns, has been documenting this shift for years with increasing alarm. The evidence is unambiguous: campaigns that invest in emotional, brand-building work generate significantly higher long-term profit contribution than campaigns that optimize exclusively for short-term activation. The ratio, established by Les Binet and Peter Field and replicated across markets and categories, is approximately 60% brand to 40% performance. The actual allocation in most large advertisers in 2026 is closer to 25% brand to 75% performance. The causes are structural and self-reinforcing. Performance advertising is measurable, attributable, and deliverable in quarterly increments. Brand advertising is slower-acting, harder to attribute, and difficult to evaluate within the reporting cycles that now govern most marketing organizations. CFOs understand cost per acquisition. They are skeptical of brand equity scores. The incentive system rewards the measurable over the effective. The consequence is a slow-motion degradation of brand assets that takes years to register in business results. Brands that defund brand-building in 2024 and 2025 will see the effects in pricing power, loyalty rates, and market share in 2027 and 2028. By the time the damage is visible, the executives who made the decisions will have moved on. This is not an argument against performance marketing. Performance advertising is a genuinely valuable tool, and the ability to measure its impact is a real advantage over the guesswork that characterized pre-digital media planning. The problem is the ratio, and the structural dynamics that keep pushing it in the wrong direction. The solution requires CFOs and CEOs to develop fluency in long-term brand metrics—something that requires patient explanation from marketing leaders who are increasingly under pressure to deliver results on 90-day cycles. It is a hard conversation to have. The alternative is watching brand equity erode while reporting impressive quarterly conversion numbers.
