I moved budget from performance to brand in a down year. Here is the math.

TL;DR: Most B2B buyers have a vendor in mind before they ever search, so last-click performance mostly harvests preference brand already built. In a tight year the instinct is to cut brand and double down on capture. The math says do the opposite, and you can defend it to finance in payback terms, not awareness terms.

I am a performance marketer. I have a LinkedIn Top Voice badge in SEM. So when I tell you I moved budget away from performance in a down year, understand that I am arguing against my own instincts and most of my own training.

I did it anyway, because the numbers stopped supporting the alternative. Here is the case I made, in the same language I made it to finance.

The uncomfortable finding underneath all of it

Forrester’s Buyers’ Journey Survey found that 92 percent of B2B buyers start their purchase with at least one vendor already in mind, and 41 percent already have a single preferred vendor before formal evaluation even begins (Forrester, via Digital Commerce 360). Forrester’s own framing is blunt: B2B buying has become a process of confirmation, not selection. The buyer decides, then goes looking for the evidence to justify the decision they already made.

Sit with what that means for a performance program. When someone searches your category and clicks your ad, there is a better-than-even chance they walked in already preferring someone. Your beautifully optimised last-click campaign is often not creating the preference. It is collecting on it.

Performance does not create the demand. It harvests what brand already planted.

That is not an argument against performance. Capture is real and it pays. It is an argument against believing performance is the whole engine, because the preference it captures had to come from somewhere, and that somewhere is the part most teams cut first when the year gets tight.

The 95:5 problem

The Ehrenberg-Bass Institute, with LinkedIn’s B2B Institute, popularised a rule that reframes the whole budget question: at any given moment only about 5 percent of your potential buyers are actually in-market, and 95 percent are not (Ehrenberg-Bass Institute). Companies replace a CRM, a bank, a CPaaS provider once every few years, not every quarter.

Performance marketing, by design, only talks to the 5 percent who are searching today. That is its job and it is good at it. But if you spend nothing reaching the 95 percent who will buy later, you are choosing to be a stranger every single time one of them finally enters the market. And a stranger loses to the vendor they already had in mind.

So the two findings stack into one problem. Most buyers arrive with a preference (Forrester), and that preference is formed over the long stretch when they are not in-market (95:5). The work that wins the deal happens before the deal exists. Performance cannot do that work, because performance is not in the room yet.

What the effectiveness data says to actually do

This is where it stops being philosophy and becomes an allocation you can defend. Binet and Field, analysing nearly a thousand IPA effectiveness case studies, found the most profitable campaigns split roughly 60 percent to brand building and 40 percent to sales activation (Razor Sharp PR summary of Binet and Field). For B2B specifically, their later work with the LinkedIn B2B Institute refined the optimal split to roughly 46 percent brand and 54 percent activation.

Two things matter about that B2B number. First, it is not 100 percent activation, which is roughly where a panicked performance-only budget ends up. Second, it is not an iron law. Binet himself says the ratio moves with category, brand size, and situation (Les Binet interview, PHD). The point is not “always spend 46 percent on brand.” The point is that the profit-maximising split has a large, non-optional brand component, and a budget that has quietly drifted to nearly all-activation is sitting on the wrong side of that curve.

How I defended it to finance

A CFO does not buy “awareness.” The mistake marketers make is walking into the budget conversation speaking a different language than the person holding the budget. So I did not argue for brand in marketing terms. I argued in theirs.

The framing that worked: performance is a harvesting cost with a fast, measurable payback, and brand is the thing that lowers the harvesting cost over time. When preference is high, you pay less to capture each deal because you are no longer bidding against indifference. When preference is low, your cost per acquisition climbs every year and you call it “the channel getting more expensive.” Defend marketing spend in the language finance already uses, payback period and LTV to CAC, not in the language of impressions (MarketingProfs on CFO budget approval).

So the down-year argument inverts. The instinct is: money is tight, cut the thing without a clean last-click number, which is brand. The math is: money is tight, so protect the thing that keeps your cost of capture from inflating, which is also brand. Cutting brand to fund performance in a hard year is borrowing efficiency from next year to make this quarter’s dashboard look busy.

What I am not saying

I am not saying turn off performance. I run performance. I am not saying brand is unmeasurable magic, it is measurable, just on a slower clock. And I am not saying spend 46 percent on brand because a study said so. Your number depends on how known you already are, your category, and how much preference you have banked.

I am saying that a performance marketer who has actually looked at where the demand comes from cannot honestly keep recommending an all-capture budget. The buyers already decided before they reached my ad. My job is to be the vendor they decided on, and that job starts long before the click.

That is the whole case. Performance harvests. Brand plants. In a down year, you protect the planting, because next year’s harvest depends on it.
