The Autumn Without Sowing

Efficiency never lies. It just won't tell you where it came from.

It's the quarterly review for the performance team. The dashboard looks good. Customer acquisition cost is down 12% from last quarter. Return on ad spend has hit 4.2. Conversion rate is the best it's ever been. The team lead is beaming. "We had a great quarter. Every metric improved."

Same meeting, different face. The brand lead isn't smiling. The share of long-term customers is shrinking. Repeat purchase rate has slipped from last year. Perception of the brand as "high quality" is trending down. More consumers say they won't buy without a discount. Two teams, talking about the same brand — one sees green lights, the other sees red. The room gets tense.

The CEO asks the obvious question: "So which team is right?" There's no good answer, because both are right. The performance team's numbers are accurate. So are the brand team's. They're just pointing in opposite directions. Every number checks out, and the overall direction is still wrong — this is exactly what the efficiency trap looks like from the inside.

There's a third piece of data that should have been on the table. Is this quarter's performance efficiency the result of accumulated brand equity, or of the performance campaigns themselves? Without an answer, there's no context linking the two teams' numbers. And without context, each set of numbers becomes a weapon each department uses to justify itself. This is the paradox at the center of it: the harder you optimize for efficiency, the faster you burn through the brand equity that made the efficiency possible in the first place. Call it the efficiency trap.

This scene keeps repeating for a reason. The meeting rooms change, the metric names change, but the structure doesn't. One side speaks in numbers that already exist. The other speaks in things that haven't become numbers yet. And the meeting usually ends in favor of whoever has the numbers. Certain figures beat uncertain judgment — that's simply how organizations default to making decisions.

The Virtue of Efficiency

There's a reason efficiency gained this much power in marketing. Twentieth-century advertising was nearly impossible to measure. "Half the money I spend on advertising is wasted; the trouble is I don't know which half." The department store magnate John Wanamaker's line summed up an industry's oldest anxiety.

Half the money I spend on advertising is wasted; the trouble is I don't know which half.

— John Wanamaker

That uncertainty started lifting sometime after the 2000s. Clicks, conversions, impressions, bounce rates — everything became a number. This measurement revolution was real progress. It let marketers cut waste, double down on what worked, and make decisions backed by evidence instead of instinct. Marketing moved closer to science. There's no arguing that was a step forward.

But that same progress created a new blind spot. Once things became measurable, an optimization race began. Squeezing more results from the same budget, bringing in more customers for less — the goal itself isn't wrong. Doing more with limited resources is every organization's job. What changed quietly, though, was the shape of the organization itself. Data analysts moved into marketing teams. Ad operations became a technical discipline. The yardstick shifted from qualitative brand value to quantitative performance metrics, and marketers who raised ROAS started getting recognized faster than marketers who built brands. When promotions and reputations are on the line, people naturally gravitate toward whatever's easier to prove.

The core logic of performance marketing is simple: run the ad, measure the response, put more money behind what works, cut what doesn't. Repeat the cycle fast enough, and efficiency climbs. A/B testing, targeting optimization, bidding algorithms — all of it accelerates the loop. The logic is self-contained, and in the short term, it genuinely works. It's hard to argue with something that visibly works.

The CFO's view reinforces all of this. Marketing has always been filed under cost, and cost is always under pressure to shrink. Performance marketing can defend its budget with a single sentence: "This spend generates this much revenue." Brand marketing can't produce that same sentence as easily. So when the economy turns or belts tighten, the brand budget — the one that can't show a direct ROI — is usually the first to get cut. This pattern, short-term financial pressure cutting long-term brand investment, repeats itself across organizations with uncanny consistency. One simple fact — what can't be measured can't be optimized, and what can't be optimized struggles to keep its budget — quietly tilts all of marketing toward measurable, short-term performance.

What this optimization logic ultimately does is erase, one by one, everything that resists measurement. What can't be measured can't be optimized. What can't be optimized has trouble getting funded. What's left is a marketing function narrowed down to short-term, measurable results. And marketing narrowed to short-term results slowly eats away at long-term brand equity.

Why does brand suffer while every metric improves?

The answer is hiding inside the word efficiency itself. Efficiency never tells you efficient *for what*. Whether today's sales came from new customers you brought in, or from interest you'd already built being cashed in early — the number doesn't distinguish between the two. Without that distinction, two genuinely different jobs marketing does get flattened into one. And those two jobs have names.

What Are Harvest and Sowing in Marketing?

Marketing does two different things. One is harvesting: finding people who are already interested in the brand and converting that interest into a sale. It targets people who already hold a favorable view of the brand, or who already intend to buy. Retargeting, search ads, promotional emails — these are harvesting tools. The other is sowing: making people who aren't yet interested aware of the brand, building a positive association, raising the odds of a future purchase. Brand advertising, content marketing, sponsorships, PR — these are sowing tools.

The trap is rooted in how differently these two operate over time. Harvesting shows results instantly. Run a retargeting ad today, and today someone buys. The checkout button gets clicked, and the number lands on the dashboard immediately. Sowing is slow. A brand ad running today won't quietly cash itself in until six months or a year later, at the exact moment a consumer decides to buy. In the meantime, nothing shows up on any dashboard. Compared purely on efficiency, harvesting wins every time — of course reaching someone already interested converts faster than reaching someone who isn't.

Here's where it turns. If budget is allocated by efficiency, harvesting gets more and sowing gets less. In the short term, this looks like the rational choice. But without sowing, there's less to harvest next time. Because the consequences of underinvesting in sowing take time to show up, the causal link rarely appears clearly in the data. Every quarter, that invisible causality quietly shaves a little more off sowing's share — without anyone feeling like they made a bad call.

Think of a single season of farming, and the structure becomes obvious. You plant in spring so you can reap in fall. Spring's sowing produces fall's harvest. But the gap between the two is long enough that a given season's harvest doesn't look connected to that same season's sowing. Today's harvest exists because of yesterday's sowing; today's sowing exists for tomorrow's harvest. When efficiency optimization cuts sowing, it isn't just making today's harvest more efficient — it's eating into the foundation for the harvest after that. Every farmer knows this. Inside a marketing organization that moves in quarters, it keeps getting forgotten.

Organizational structure plays its part too. The person responsible for harvesting and the person responsible for sowing sit on different teams, answer to different KPIs, report up through different lines. Each does their best within their own lane. The performance team manages this quarter's conversion rate; the brand team manages long-term awareness. But the question — "is enough being planted right now for next season's field?" — often has no one holding it for the whole. So the shortfall in sowing doesn't arrive like an accident. It arrives like rot: slow, and unnoticed until it isn't.

The 60:40 Ratio

There's research that puts numbers behind this structure. The British marketing researchers Les Binet and Peter Field analyzed hundreds of campaigns in the IPA (Institute of Practitioners in Advertising) Effectiveness Databank. Comparing the effects of short-term activation campaigns against long-term brand-building campaigns, they found that the marketing mix most effective for long-term brand growth allocated roughly 60% to brand marketing (sowing) and 40% to performance marketing (harvesting). Most companies do the opposite, spending more on performance marketing. Chasing efficiency naturally produces this reversal. No one decides it on purpose — it's the sum of many individually rational quarterly choices.

Binet and Field's research makes one more point worth sitting with: brand marketing and performance marketing don't compete with each other — they reinforce each other. A strong brand raises the ROAS of performance marketing, because consumers who already know and like the brand respond better to ads. Without brand marketing, performance efficiency quietly declines too. Run both together, and each amplifies the other.

Whether today's high ROAS comes from brand equity or from the performance campaign itself — short-term metrics alone can't tell you.

This reinforcement is invisible if you only look at short-term metrics. A ROAS of 4.2 doesn't say where the 4.2 came from. So the performance team reads its number as pure skill, and no one factors in that a good part of that number came from seeds the brand team planted years earlier. The two teams' results are actually entangled — but the way they're measured erases the entanglement.

The 60:40 split isn't a perfect formula. The right ratio can shift depending on category and where a brand is in its growth. What makes the number meaningful is the direction it points in. Large-scale campaign data consistently says sowing deserves more credit than it gets — yet viewed only through the lens of efficiency, organizations keep walking the other way. The lens itself is bending the direction.

Why Both Team Leads Were Right

Back to where we started. The performance lead and the brand lead weren't lying to each other. They were just looking at different timelines. One was counting what's being reaped right now; the other was watching how many seeds were left for next time. The question the CEO should have asked wasn't "who's right" — it was "what is this efficiency standing on?"

Leave that question unasked, and the trap deepens on its own confidence. Cutting sowing doesn't show up right away. Because accumulated brand equity is still there, performance metrics stay good for a while longer. And that good performance gets read as confirmation that chasing efficiency was the right call. Confirmation justifies the same decision one more time. By the time the problem becomes visible, several seasons have already passed — and by then, it gets explained away as "competition got tougher" or "the market's hard right now." The moment the cause gets pinned on something outside instead of the missing sowing, the same decision gets made again.

This is exactly why the efficiency trap is so hard to climb out of. Inside the trap, performance looks better, not worse. Where an alarm should go off, applause goes off instead. The first real signal that something's wrong usually arrives only after a substantial amount of equity has already been spent. And rebuilding that equity takes far longer than it took to burn through it. A field that skips spring doesn't refill itself by the following fall.

Efficiency isn't a bad goal. The trouble starts when it becomes the only yardstick — when harvesting always gets chosen over sowing. That's the moment an organization starts eating into next spring's field to make this fall's numbers look good. The bill doesn't arrive right away. It arrives the following season, when you notice the empty patch where nothing was planted. The next installments in this series look at exactly where that empty patch shows up, and in what form.

Efficiency tells you how much you reaped. It never tells you who planted the seed.
