The CMO Role Is Changing. Most Advice About It Hasn’t.

The CMO industry is one of the most scrutinised, debated, and misunderstood corners of corporate life. CMOs have the shortest average tenure of any C-suite executive, yet the expectations placed on them keep expanding. They are asked to own brand and performance, short-term revenue and long-term equity, internal culture and external positioning, all at once.

Understanding what is actually happening in the CMO industry, not the version sold in conference keynotes, matters whether you are a marketer building toward that seat, a business leader hiring for it, or a CMO trying to stay in it.

I have spent more than 20 years in marketing and agency leadership. I have worked with CMOs across 30 industries, watched some thrive and watched others get quietly removed after 18 months despite doing good work. The patterns are consistent enough that they are worth naming plainly.

Why CMO Tenure Is Short and Getting Shorter

The average CMO tenure at large companies has been declining for years. Various industry trackers put it somewhere between 28 and 40 months depending on company size and sector. That is significantly shorter than the average CFO or COO tenure, and the gap has widened.

The standard explanation is that marketing is hard to measure, so CMOs get blamed when results disappoint. That is partially true but it misses the structural issue. CMOs often walk into roles where the brief is contradictory from day one. The CEO wants brand-building and immediate revenue. The CFO wants accountability and lower costs. The board wants market share growth and margin improvement. These things are not always compatible over a 12-month horizon, and the CMO is the person who gets removed when the tension becomes visible.

I have seen this play out directly. One of the agency turnarounds I led involved working closely with a newly appointed CMO at a mid-market business. She was talented, commercially sharp, and had a clear strategy. But she had inherited a marketing function that had been underfunded for three years, a brand with declining awareness, and a sales team that had been generating short-term volume through discounting. She was given 12 months to fix it. The structural problems predated her by years. She lasted 14 months.

The CMO tenure problem is not primarily a skills problem. It is an expectation management problem, compounded by the fact that marketing outcomes take time to compound while career consequences arrive on a quarterly cycle.

If you are thinking seriously about marketing leadership at the senior level, the Career and Leadership in Marketing hub covers the full range of these dynamics, from how the role is evolving to how practitioners are building more sustainable career models.

The Commercial Credibility Gap

There is a version of the CMO who is excellent at marketing and genuinely poor at business. They understand brand, creative, channels, and audiences. They struggle to read a P&L, have limited influence in board conversations, and cannot connect their activity to the commercial metrics the business actually cares about.

This is not a character flaw. It reflects how many marketers are trained and how many marketing functions are structured. If you spend the first decade of your career in a marketing department that is measured on impressions, engagement rates, and campaign delivery, you develop fluency in those metrics. Commercial fluency requires a different kind of exposure.

When I was building out the team at iProspect, growing from around 20 people to over 100, one of the things I noticed consistently was that the marketers who progressed fastest were not always the most technically skilled. They were the ones who could talk to clients in commercial terms. Not “your click-through rate improved by 18%” but “your cost per acquired customer dropped, which means you can afford to spend more to reach new audiences without eroding margin.” That translation skill matters enormously at the CMO level.

The CMOs I have seen succeed long-term share a common characteristic: they treat marketing as a business support function, not as a discipline that exists to celebrate itself. Awards, creative acclaim, and channel innovation are only relevant if they connect to something the business needs. When they do not, they are theatre.

The adoption of new marketing channels has always outpaced the commercial frameworks used to evaluate them. CMOs who chase channel novelty without commercial grounding tend to produce impressive-looking activity and disappointing business results.

The Performance Marketing Trap

A significant portion of the CMO industry spent the last decade over-investing in lower-funnel performance channels and under-investing in brand. The logic seemed sound: performance channels are measurable, attributable, and responsive. You could see the return. You could optimise in real time. Boards liked the clarity.

The problem is that a substantial amount of what performance marketing gets credited for was going to happen anyway. When someone searches for your brand name and clicks a paid ad, the attribution model records a conversion. But that person already knew who you were. They were already inclined to buy. The ad captured intent that existed before the ad ran.

I think about it like a clothes shop. If someone walks in, picks something up, and tries it on, they are already 10 times more likely to buy than someone who walked past the window. The act of trying it on did not create the desire. It captured it. Performance marketing often works the same way. It is excellent at closing. It is poor at creating the conditions that make closing possible.

The CMOs who built genuinely durable growth were the ones who maintained investment in brand and upper-funnel activity even when it was harder to justify in a quarterly review. They understood that reaching new audiences, people who do not yet know you exist, is the only reliable route to sustainable growth. Capturing existing demand has a ceiling. Creating new demand does not.

This distinction matters enormously when CMOs are making budget allocation decisions. A channel strategy that looks efficient in the attribution model can be quietly starving the business of the brand investment it needs to grow beyond its current customer base.

How the CMO Role Is Splitting Into Two Versions

The CMO title covers an increasingly wide range of actual roles. At one end, there is the commercially accountable growth leader: a senior executive who owns revenue contribution, has real influence over product and pricing decisions, and is measured on outcomes the business cares about. At the other end, there is the brand figurehead: a senior marketer with impressive credentials, a large team, and limited operational power over the things that actually drive growth.

Both versions exist at major companies. They are not always easy to distinguish from the outside. The job description often looks similar. The difference shows up in reporting lines, budget authority, and how much of the commercial conversation the CMO is actually part of.

Marketers who are building toward the CMO role need to be honest with themselves about which version they are pursuing and which version the companies they are joining actually have. Walking into a brand figurehead role expecting to operate as a growth leader is a reliable path to frustration and a short tenure.

The Marketing Leadership Council is a useful reference point for understanding how senior marketing leadership is evolving across different business contexts, and what the expectations of the role look like in practice.

The Rise of Flexible CMO Models

One of the most significant structural shifts in the CMO industry over the past decade is the growth of flexible engagement models. Businesses that previously would have hired a full-time CMO are increasingly exploring alternatives: fractional arrangements, interim appointments, and project-based senior marketing leadership.

This is not simply a cost-cutting measure, though cost is a factor. It reflects a genuine change in how businesses think about senior marketing capability. A scaling business that needs strategic marketing leadership for 18 months while it prepares for a funding round does not necessarily need a permanent CMO. A company going through a rebrand or a market entry does not need to add a full-time executive headcount to access that level of expertise.

The CMO as a Service model addresses exactly this need: senior marketing leadership delivered on a flexible basis, without the overhead and structural commitment of a permanent hire. For many businesses, this is a more commercially rational approach than the traditional model.

Fractional marketing leadership has moved from a niche arrangement to a recognised engagement model, particularly in the mid-market. Companies with revenues between £5m and £50m often cannot justify a full-time CMO salary but genuinely need that level of strategic input to compete effectively.

There is also a growing market for interim CMO services in situations where a business needs to bridge a gap, whether between permanent hires, during a restructure, or while the leadership team works out what kind of marketing function it actually needs. The interim model works well precisely because it is time-bounded and outcome-focused from the start.

For businesses that want senior marketing capability without the complexity of a formal interim arrangement, the CMO for hire model offers a more direct route. And for organisations that need senior marketing leadership at the director level rather than the C-suite, an interim marketing director can provide the operational depth and strategic grounding the business needs without overspecifying the brief.

What these models have in common is that they decouple senior marketing expertise from the traditional employment structure. That is a meaningful development for the industry, and one that is likely to continue as businesses become more sophisticated about how they access capability.

What the Effie Awards Taught Me About Marketing Effectiveness

Judging the Effie Awards gave me a specific kind of perspective on the CMO industry that I would not have got any other way. The Effies are the effectiveness awards, the ones that require entrants to demonstrate commercial impact rather than just creative quality. You see the full case: the brief, the strategy, the execution, and the results.

What struck me most was not the quality of the winning work. It was the quality of the thinking behind it. The campaigns that stood out were the ones where the marketing team had clearly understood the commercial problem before they started building the solution. They knew what the business needed, they knew why the current approach was not delivering it, and they had a clear hypothesis about what would change if they got the marketing right.

The campaigns that fell short, even some with impressive creative, were the ones where the commercial logic was retrofitted. The work was made, it performed reasonably well on some metrics, and then someone built a narrative around it afterward. That is not effectiveness. That is post-rationalisation.

CMOs who want to build credibility with their boards and their CEOs need to get comfortable with the effectiveness framework before the campaign runs, not after. That means being clear about what commercial outcome you are trying to move, what the baseline is, and what a meaningful improvement looks like. It also means being honest when the results do not support the narrative you hoped for.

Tools like on-site survey tools and behavioural analytics can help CMOs build a more honest picture of customer behaviour, but they are a perspective on reality, not reality itself. The CMOs I have seen use data well are the ones who treat it as one input into a commercial judgment, not as a substitute for one.

What the CMO Industry Gets Wrong About Measurement

The measurement conversation in marketing has been dominated for years by a false choice between perfect attribution and no accountability. Neither position is commercially useful.

Perfect attribution is a myth. Marketing influences behaviour across time, across channels, and across touchpoints in ways that no attribution model fully captures. Anyone who tells you their multi-touch attribution model gives them a complete picture of how marketing drives revenue is either uninformed or overselling their stack.

But the response to imperfect measurement is not to abandon accountability. It is to develop honest approximations and make decisions based on the best available evidence, with appropriate humility about what you do not know. CMOs who hide behind measurement complexity to avoid commercial accountability do not last, and they probably should not.

The more productive framing is to distinguish between what you can measure precisely, what you can measure approximately, and what you can only infer. Brand health metrics, for instance, are imprecise but they are not meaningless. Share of voice data is an approximation but it correlates with market share over time. Incremental lift testing is more reliable than last-click attribution for understanding channel contribution, but it requires patience and a willingness to run experiments that may not show what you hoped.

Understanding how tracking and tagging infrastructure works, including tools like Google Tag Manager, matters for CMOs who want to have credible conversations about measurement with their analytics and technology teams. You do not need to be a technical expert, but you need to understand the principles well enough to ask the right questions.

The CMOs who build lasting credibility on measurement are the ones who are transparent about uncertainty, consistent in their methodology, and honest when the numbers do not support the story they would prefer to tell.

Where the CMO Industry Is Heading

The CMO role is not disappearing. But it is changing in ways that will disadvantage marketers who have built their careers on channel expertise alone, and advantage those who have built commercial credibility alongside their marketing skills.

AI is accelerating the commoditisation of execution. Content production, campaign management, audience segmentation, and performance optimisation are all becoming faster and cheaper. The activities that justified large marketing headcounts are being automated at a pace that will reshape marketing organisations over the next five years. CMOs who have positioned themselves as experts in these execution layers are more exposed than they may realise.

The activities that are harder to automate are judgment, commercial strategy, and the ability to connect marketing decisions to business outcomes. Those are the capabilities that will define the CMO role in its next iteration. Tools like AI writing and content tools are already changing what marketing teams produce and how quickly, but they do not replace the commercial thinking that determines whether any of it is pointed in the right direction.

The flexible CMO models I described earlier are also likely to become more mainstream, not less. As AI reduces the cost of execution, the premium on strategic leadership increases. Businesses will want access to genuinely senior commercial marketing thinking, and they will increasingly find that the flexible models deliver that more efficiently than the traditional permanent hire.

For marketers building toward the CMO level, the implication is clear. Develop commercial fluency early. Get close to the P&L. Understand how the business makes money and where marketing genuinely contributes to that. Build a track record of connecting activity to outcomes, not just delivering activity. And be honest about the difference between the two.

The CMO industry has always rewarded people who can think clearly about commercial problems. That is not changing. What is changing is the bar for what “clearly” means, and how quickly the gap between those who can and those who cannot becomes visible.

There is more on these themes across the Career and Leadership in Marketing hub, including how senior marketers are building more sustainable career models in a role that has historically been unforgiving of even good performers.
