Why marketers need one lead agency accountable for creative, media, measurement and growth

Your consumers do not experience your multi-ad agency roster.

They do not know that one agency made the awareness campaign, another handles social content, a third manages retail media, a fourth buys search and someone else built the reporting dashboard.

They experience one brand.

That is why I believe marketers should have one lead agency responsible for the entire advertising system— upper funnel, middle funnel and lower funnel; creative and media; reporting and optimization.

Other specialist partners can absolutely contribute. But one agency must be the captain of the ship. One agency must see the whole field, work closely with the client and be accountable for the business result: sales, subscriptions, downloads, store visits, qualified leads or whatever outcome actually matters.

When everyone owns one piece of the funnel, no one truly owns the performance of the whole.

While many will retort that “the whole” is the marketers job. I’d agree, but show how the marketer is more likley not structured correctly or lacks tools and talent.

The consumer journey is not linear. Accountability still should be.

Let’s acknowledge the obvious: a prospective customer can first encounter a brand almost anywhere.

The first exposure might be a television commercial, a creator’s post, a Google search result, a retail media placement, a friend’s recommendation or the package sitting on a store shelf. Google reports that eight in ten online purchases involve multiple touchpoints, confirming what marketers see every day: people stream, scroll, search and shop in combinations that do not resemble a neat, predictable funnel.

But “nonlinear” does not mean “unconnected.”

If my first exposure to an unfamiliar brand is at the shelf, I may notice it. I may even pick it up. But depending on the category, price and perceived risk, I am probably not buying it until I learn more. I want to know what it does, why it is different, whether I should trust it and whether people like me believe it is worth the money.

One exposure can create a spark. It rarely creates enough confidence to close the sale.

At Left Off Madison, we call this“3-to-8 To Motivate”: most prospects need three to eight meaningful exposures before they act. Not three to eight repetitions of the same ad in the same channel. Meaningful, reinforcing exposures across different environments, each doing its part to build awareness, interest, credibility and motivation.

That only works when someone is designing and managing the exposures as one connected system.

Lower-funnel media cannot harvest demand that was never created

Nothing concerns me more than a brand overinvesting in conversion tactics simply because those tactics are easiest to measure.

Retail media, remarketing, paid search and promotional activity all have a role. They can be exceptionally effective when they capture existing intent and convert it efficiently. But they are not substitutes for making more people know the brand, understand its value and care enough to consider it.

Imagine a nationally distributed brand with only one million users persistently spending $10 million on lower-funnel activity— and little or nothing else. If the business objective is household penetration, does that make sense?

It does not to me.

The plan may generate attractive click-through rates, return-on-ad-spend reports and retailer dashboards. It may keep serving ads to people who already know the product, already visited the site or were already close to buying. But eventually the brand is fishing in the same pond, paying more to reach the same people and calling the activity “efficient” because the platform can attribute the last click.

That is not necessarily growth. It may simply be the increasingly expensive conversion of demand the brand already had.

The industry’s own data reveals the imbalance. Nielsen found that 70% of global marketers planned to prioritize performance marketing over brand building, even though their leading KPIs were long-term ROI and full-funnel ROI. WARC’s 2025 Multiplier Effect analysis concluded that moving from a performance-only strategy to a combined brand-and-performance approach can increase total revenue returns by 25% to 100%, with a median uplift of 90%.

The point is not that every brand needs an arbitrary 60/40 allocation. The right balance depends on awareness, penetration, category, purchase cycle, distribution, margins and business goals. The point is that lower-funnel efficiency eventually hits a ceiling when too few new people are entering the market for your brand.

You cannot optimize your way out of being unknown.

Buzz is not a business outcome, either

The opposite mistake is just as common, especially among newer brands.

A marketer puts nearly every egg into creators, a fashionable partnership, product sampling or a trendy event. The expectation is that a “love virus” will suddenly break out, transform the brand into a cultural darling and send sales soaring overnight.

Could it happen? Certainly.

Is hope a measurement strategy? Absolutely not.

Influencer activity, sampling and experiential marketing can introduce a product, generate social proof and accelerate consideration. But what is the business-driving goal? Who are we trying to influence? What behavior should change? How will exposure connect to search, site traffic, trial, retail velocity, repeat purchase or another measurable result? What happens after the event ends and the posts disappear from the feed?

Buzz without a defined commercial objective is applause without a scoreboard.

Upper-funnel activity should not get a pass on accountability simply because its effect can take longer to appear. Lower-funnel activity should not receive all the credit simply because it happened closest to the transaction. Every part of the plan needs an assigned job, a meaningful KPI and a connection to the final business outcome.

Fragmented agency rosters produce fragmented accountability

The typical full-funnel agency model almost guarantees conflict.

The awareness agency is rewarded for reach, impressions and brand lift. The engagement agency points to views, likes, shares and earned conversation. The performance agency reports clicks, conversions and return on ad spend. The creative agency wants consistency. The media agency wants more versions, faster. The retailer grades only what happened inside its own platform.

Each partner can produce a defensible report showing that its portion worked.

Meanwhile, the marketer is left to answer the only question senior leadership cares about: Did the total investment grow the business?

For decades, the agency industry has separated creative and media into different entities, teams and profit centers. Once the disciplines were separated, the incentives separated with them. When a client’s business softened, creative could blame the media plan. Media could blame the creative. Both could blame the budget, the brief, the product, the sales team or the economy.

Now multiply that dynamic across an entire roster of upper-, middle- and lower-funnel partners.

Silos form. Data stays inside platforms. Creative ideas become disconnected executions. Agencies protect their assigned budget instead of questioning whether it still belongs there. Optimization happens within channels rather than across the total investment. No one wants to recommend moving money away from the activity that pays their fee.

The client becomes the integrator, referee, translator, traffic manager and marriage counselor.

And, as we explored in “Marketing Insanity: Expecting Better Results From Teams that were Never Trained,” many marketers have never received comprehensive training in how strategy, creative, media, production and measurement work together. We then give them five agencies to manage and act surprised when the system becomes slow, political and exhausting.

The budget should be fluid. Accountability should not be.

Every campaign begins with an allocation based on the best information available at the time. That allocation is a hypothesis— not a treaty.

The first governance mistake is failing to tell every partner that the budget can and will move. If awareness is the constraint, more money may need to move upward. If people know the brand but do not understand why it is relevant, the middle needs reinforcement. If consideration is strong but conversion is weak, the answer may sit in lower-funnel media, the offer, the landing experience, distribution—or the creative.

No agency should be entitled to a fixed percentage simply because its name appeared next to a line in the original plan.

One lead agency should continually ask:

  • Where is the greatest constraint on growth right now?

  • Which audience needs to move, and what must they believe or do next?

  • Is the creative doing the correct job at each stage?

  • What does the combined data say—not merely each platform’s self-reported result?

  • Where will the next dollar produce the greatest incremental return?

That agency should operate the backend reporting, reconcile the data, identify changes in performance and recommend budget shifts in close partnership with the client. The client retains authority. The lead agency supplies the integrated view, judgment and accountability.

Nielsen’s research shows why that role matters:84% of marketers expressed high confidence in their ROI measurement, but only 38% measured traditional and digital marketing together. Confidence is not the same as completeness. A dashboard can be precise and still describe only one corner of the business.

By contrast, McKinsey reports that a thoughtful, data-driven full-funnel strategy can produce a15% to 20% lift in marketing ROIby reallocating media toward higher-return opportunities and applying test-and-learn optimization. In another analysis, McKinsey found that optimizing creative rotation through unified marketing-ROI measurement increased advertising’s impact on sales by 14%.

Integration is not merely tidier. It can be more productive.

One lead agency does not mean one agency must do everything

I am not arguing that every specialist should be fired or that one agency will always possess every niche capability.

I am arguing for one operating system.

One lead agency should own the audience strategy, journey, creative architecture, media logic, measurement framework, consolidated reporting and optimization recommendations. Specialist agencies, platforms, creators, production companies and retail partners can plug into that system as supporting actors.

But they should work from the same brief. They should share the same business goals. Their results should feed the same source of truth. And when evidence says the budget should move, the system should allow it to move.

The lead agency must also be willing to move money away from its own favorite idea or capability. Being captain is not permission to protect turf. It is the obligation to make the best decision for the client’s business—even when another partner should receive the assignment or the budget.

One brand. One budget. One accountable lead.

Customers do not live in funnels. They move backward, forward and sideways. They discover at the bottom, investigate in the middle, build confidence at the top and convert wherever the opportunity becomes easy and credible.

That complexity is the reason to integrate leadership— not the reason to fragment it.

Marketers need one agency that can connect what people see, what they believe, what they do and what the business earns. One agency that can join creative and media. One agency that can tell the difference between activity and progress. One agency that can see when demand needs to be created, when consideration needs to be strengthened and when intent is ready to be converted.

The marketer’s job should be to set the business priorities, challenge the thinking and make consequential decisions—not spend half the week reconciling competing agency narratives and incompatible dashboards.

Give the funnel one captain.

Then hold that captain accountable for getting the ship where the business needs to go.

Who is captaining yours?

At Left Off Madison, this is how we believe an agency should work. We connect audience insight, strategy, creative, media, production, reporting and optimization around one shared business objective. We stay close enough to the work—and to our clients—to recognize when something needs to change and move quickly when it does.

If your marketing program contains plenty of activity but no single partner can explain how it all adds up to growth, perhaps the first thing to optimize is not another campaign, channel or tactic.

Perhaps it is the operating model itself.

If your brand needs one accountable lead across the full funnel, we would welcome the responsibility.
