Advertising Across the Funnel: From Performance Obsession to Sustainable Growth

Performance marketing has become the backbone of modern growth strategies. Today, 80% of marketers prioritize it over brand building, and the highest-performing teams lean into it even more. 

The appeal is clear: faster feedback loops, channel-level attribution, and results leaders can stand behind.

At the same time, confidence in those results is slipping. According to our research, nearly nine in 10 marketers say gaps in measurement reduce their trust in channel performance, and cross-funnel measurement remains the single biggest barrier to success. 

Teams optimize aggressively at the bottom of the funnel, while the activity that creates demand higher up becomes harder to connect, more difficult to defend, and easier to deprioritize.

As we look toward 2026, sustainable growth requires a more complete view of advertising: Performance works best when it has demand to capture, and brand works best when its impact on downstream results is understood. 

The next stage of growth comes from measuring how these efforts work together across the funnel and using that understanding to make more durable investment decisions.

The Performance Obsession: Rational Behavior, Unintended Consequences

The industry’s shift toward performance marketing reflects how success is measured. Over the past decade, marketers invested heavily in attribution models and optimization frameworks designed to prove value quickly and precisely. 

That investment paid off: top-performing teams are three times more likely to focus heavily on performance marketing.

From a leadership standpoint, the appeal is clear: 

• Performance offers clarity under pressure. 
• Spend can be traced to outcomes, results can be defended, and optimization happens. 
• For many organizations, it became the safest path to growth.

The tradeoff is what that system deprioritizes. 

When success is defined by short-term certainty, activity that creates demand earlier in the funnel becomes harder to justify. 

Brand and awareness don’t disappear, but they move to the margins—underfunded and under-measured—because their impact shows up later and elsewhere.

Performance captures demand efficiently, but it doesn’t create it. When teams focus primarily on converting people who are already ready to buy, the funnel narrows. Results can continue to look strong, even as efficiency declines and costs rise.

This isn’t a failure of performance marketing. It’s a limitation of how success is defined and measured. As more budget flows toward what closes, marketers optimize the bottom of the funnel without a clear understanding of what sustains it—setting the stage for a broader measurement challenge.

The Activation Gap: Better at Optimization, Worse at Understanding

Measurement has evolved alongside performance marketing, but not in the way leaders expected. The industry has become highly effective at optimizing campaigns in real time, while losing clarity on what actually drives growth across the funnel.

Marketers now operate with more data than ever, yet confidence continues to decline, especially when evaluating activity beyond the bottom of the funnel. 

The challenge here is fragmentation. Most measurement frameworks are built around channels and short-term outcomes, making it difficult to connect early-stage investment to downstream performance.

As a result, teams optimize what they can see. Bids are adjusted, audiences refined, and budgets shifted based on immediate signals. 

These actions improve efficiency in the moment, but they answer a limited question: how to improve performance right now. They offer far less insight into how demand is created, sustained, and converted over time.

This gap shows up most clearly in brand and awareness efforts. When their impact can’t be tied directly to revenue, they feel risky, even when they support performance outcomes later. 

Marketers become increasingly skilled at turning the knobs, while growing less certain about which knobs matter. Without cross-funnel measurement, optimization accelerates—but understanding falls behind.

The Hidden Cost of Siloed Measurement

When measurement is siloed by channel and funnel stage, optimization decisions drift away from what actually drives growth. The clearest example shows up in how demand is created versus how it’s captured.

Upper-funnel investment often creates awareness and interest that converts later through search, retargeting, or direct traffic. But last-touch and channel-level attribution credit the closer, not the creator. Performance channels appear more efficient, while the activity that generated demand looks expendable.

Over time, budget follows the numbers. Spend shifts toward channels that close, and away from those that warm the audience. Optimization improves conversion efficiency in the short term, while the system that feeds the funnel weakens. What looks like smart optimization becomes a slow erosion of future demand.

This is how teams optimize parts of the funnel while undermining the whole. Without measurement that connects brand activity to downstream outcomes, leaders make rational decisions based on incomplete signals, trading long-term growth for short-term certainty without realizing it.

The Long-Term Value Paradox: Growth Without Proof

Many marketers recognize the long-term value of aligning brand and performance. The challenge is proving it in a way that holds up under scrutiny. 

When brand impact can’t be clearly connected to downstream results, it remains vulnerable, especially when budgets tighten.

This creates a paradox. Brand plays a critical role in building demand, shaping preference, and improving performance efficiency over time, yet most measurement systems are designed to evaluate it separately from conversion-driven activity. The value is real, but the proof is fragmented.

As a result, brand investment often depends on belief rather than evidence. Leaders understand its importance, but lack the measurement needed to explain how brand activity strengthens performance outcomes. Without that connection, conversations about long-term growth stay theoretical, while short-term metrics continue to dictate decisions.

Resolving this paradox requires a shift in how success is measured. Growth depends on understanding how brand and performance work together as a system—how early-stage investment influences later outcomes, and how those effects compound over time. 

When measurement makes that relationship visible, brand becomes a measurable input to performance, not a leap of faith.

Advertising Across the Funnel: A Systems View of Growth

Advertising across the funnel requires treating growth as a connected system, not a series of independent optimizations. Brand and performance no longer operate as separate motions with separate success criteria. They work together, whether measurement captures it or not.

The shift starts with how success is defined. Instead of evaluating channels in isolation, leading teams measure how activity at one stage influences outcomes at the next. Early-stage investment is assessed by its ability to create demand that converts later, not by forcing it to behave like a performance channel.

Measurement evolves alongside this mindset. Incrementality replaces isolated attribution, and cross-funnel analysis provides context for performance results. Optimization still matters, but it’s guided by an understanding of cause and effect across the entire journey.

This systems view changes how decisions are made. Budget allocation reflects both short-term efficiency and long-term impact. 

Performance channels capture demand more effectively because brand has created it. And leaders can see how it works, without simplifying the funnel.

What Leading Marketers Do Differently

Leading marketers approach full-funnel advertising as a growth system, not a set of disconnected tactics. 

• They plan brand and performance together, aligning teams around shared outcomes rather than separate KPIs. Demand creation and demand capture are treated as complementary forces, each strengthening the other over time.
• They invest in measurement that explains performance, not just reports it. Instead of relying solely on channel-level attribution, they look for evidence of incrementality and downstream impact. Optimization still matters, but it’s guided by an understanding of how early-stage investment influences later results.
• Most importantly, they protect the top of the funnel. Even under pressure, they maintain investment in awareness and consideration because they can see how it improves efficiency lower down. Performance works harder when demand is healthy, and growth becomes more predictable when the full system is measured and understood.

Advertising across the funnel in 2026 rewards marketers who connect these dots. The advantage doesn’t come from choosing brand or performance, but from seeing how they work together and acting on that insight with confidence.
