Performance marketing made a promise: every pound of spend traceable, every outcome measurable, every channel accountable. That promise was never entirely true, but it was persuasive enough to shift enormous volumes of budget away from brand building toward activation — paid search, paid social, programmatic display, retargeting. The results, for many brands, have been a decade of improving short-term return on ad spend and quietly deteriorating pricing power, market share, and customer acquisition cost.
The evidence is not new. The resistance to acting on it, however, remains strong. Because brand investment is harder to defend in a quarterly performance review than a cost per acquisition figure. And because the people making budget decisions are rarely the people who understand what brand actually does to commercial performance over time.
What brand investment actually buys
Brand investment builds the future audience for your performance marketing. It increases the pool of people who, when they encounter your paid search ad or your retargeting creative, are already predisposed to consider you. It reduces the friction in the conversion funnel because recognisable, trusted brands convert at higher rates from the same impression volume. It supports pricing power because buyers who feel an emotional connection to a brand are measurably less sensitive to price than those who are transacting on rational criteria alone.
None of these effects show up in a 30-day attribution window. Most show up slowly, over 6 to 18 months, in metrics that performance-focused reporting is not set up to track. This is the measurement problem that allows brand budgets to be cut without visible immediate consequence — the cuts show up later, in rising CPAs, declining close rates, and increased price sensitivity, by which time the connection to the brand budget decision is invisible to the people reviewing the numbers.
The compounding effect most marketers ignore
Brand building is a compounding activity. A year of consistent, quality brand investment produces effects that are larger than the sum of each campaign in isolation, because each piece of activity builds on the memory and associations created by what came before. This compounding is real and well-documented — IPA Effectiveness research consistently shows that brands which maintain investment through difficult periods outperform those that cut, not just during the recovery but for years afterward. The brands that cut brand spend to protect short-term profitability are typically borrowing from the future. The debt becomes visible eventually.
Cutting brand investment to protect short-term margin is borrowing from the future. The debt becomes visible eventually — usually when the CPA problem is already severe.
How to make the case internally
The argument for brand investment fails when it is made in the language of marketing. It succeeds when it is made in the language of commercial strategy. The question is not "should we invest in brand?" — that framing puts the marketing team on the defensive. The question is "what is our strategy for defending and growing margin in a market where product differentiation is increasingly hard to sustain?" Brand is a viable answer to that question. Continued investment in performance without brand support is not.
Frame it as a risk management argument
One approach that works well with finance and commercial leadership is framing brand investment as a hedge against rising customer acquisition costs. As any paid channel matures, competition increases and efficiency declines. The brands that have built strong organic and brand equity are meaningfully insulated from that inflation. The brands that have not must pay more each year for the same volume of attention. Brand investment is, in part, insurance against the rising cost of performance media.
Use the 60/40 principle
The research on optimal budget split between brand building and activation — approximately 60% toward brand, 40% toward performance — is among the most replicated findings in marketing effectiveness. The WARC database of effectiveness evidence consistently shows this range delivers the highest long-run return on marketing investment, with significant degradation when the split moves below 40% on the brand side. Using published effectiveness research to anchor the budget conversation removes it from the realm of opinion and puts it in the realm of evidence.
The practical starting point
You do not need to win the full 60/40 argument in a single budget cycle. The more effective approach is to protect what brand budget you have, document what it delivers over time in metrics that connect to commercial outcomes — share of search, aided awareness in target segments, brand preference in competitive consideration sets — and build the evidence base that makes the next conversation easier.
Start by agreeing on how brand performance will be measured. The absence of a measurement framework is what allows brand investment to feel like faith rather than strategy. Once you have agreed metrics, agreed timelines, and a track record of results, the argument for maintaining or growing brand investment becomes much harder to resist.
The brands winning in competitive markets are not the ones that chose between brand and performance. They are the ones that understood how each makes the other more effective — and funded both accordingly.
