The budget allocation question every CMO gets wrong

The market has tilted, and not by accident

The money is moving in one direction. Gartner found that awareness and conversion now account for 62.6% of total media spend, up more than ten points since 2024, while loyalty and retention spend fell 29%. The funnel is being squeezed from both ends, and the middle is being starved.

That happens against a tight backdrop. Marketing budgets sit at roughly 7.8% of company revenue in 2026, barely up on 2025. There is no slack. Every point you misallocate is a point you do not get back.

Why your attribution is lying to you

Here is the trap. At any moment, only about 5% of B2B buyers are in-market for what you sell, a finding popularised by Ehrenberg-Bass and John Dawes as the 95-5 rule. Performance media is very good at harvesting that 5%. It is structurally blind to the 95% who will buy later and remember whoever built mental availability first.

Attribution rewards what it can see. It sees the last click, so it credits the harvest and defunds the planting. Follow it and you slowly hollow out the demand that made the harvest possible in the first place.

The ratio the best players actually run

The work of Binet and Field with the LinkedIn B2B Institute points to a workable rule. The optimal long-run split is roughly 60/40 brand to activation for B2C, and closer to 46/54 for B2B. Note that even in B2B, where buying cycles are long and rational, brand earns nearly half the budget.

Spend above your market share matters too. Excess share of voice, or ESOV, is the gap between your share of category spend and your share of market. The Nielsen and IPA modelling points to around a 0.5% growth return per point of ESOV, rising to roughly 0.6% in B2B per Binet and Field. The mechanism is dull and reliable. Outspend your share of market, grow into it.

Budget beats ROI

The most uncomfortable finding for a returns-obsessed board comes from Les Binet, speaking to Mi3 in June 2026. ROI is not the growth engine. The size of the budget is up to nine times more important to profit than its efficiency. Optimising a small budget to perfection still leaves you small. This is the line that should reframe the conversation in the boardroom: stop polishing the ROI on a budget that is too timid to move the number.

Prove it before you scale it

None of this is faith-based. Incrementality testing is now used by 52% of US marketers, and modern marketing mix modelling is no longer the preserve of the giants. Open-source MMM is accessible today, led by Google Meridian and PyMC-Marketing. You can model the contribution of brand and activation, run geo-based lift tests, and put a defensible number in front of the CFO before you commit.

The landmark cases still hold the lesson. Between 2019 and 2021, Adidas reviewed a media mix that had run roughly 23% brand and 77% performance. The company's own disclosure, via Simon Peel in 2019, was that brand had actually driven around 65% of sales. Airbnb made a similar move over the same window, shifting weight from performance back to brand. Different businesses, same correction.

The point is not to copy a ratio off a slide. It is to own one number, the long-run profit number, and to allocate against it rather than against whatever the attribution dashboard happened to credit last week. That is the job of one accountable partner who owns the outcome end to end, not a stack of channel specialists each defending their own line. At Ruckus, that is the whole point. One partner, one number, brand and performance balanced on purpose.
