Marketing Agencies Suck.

The problem with marketing agencies is rarely a lack of talent. It is a business model that asks outsiders to understand a company quickly, deliver something visible, prove they fulfilled the contract, and move on before they have learned enough to become truly useful.


Marketing does not improve through a succession of fresh starts. It improves when knowledge survives: when one campaign informs the next, customer reactions change the strategy, and lessons travel through the organization instead of disappearing with the account team.


If you cannot build that competence in-house, you do not need an agency that rents you campaigns. You need a long-term performance partner.


Marketing agencies suck, not because the people who work in them lack talent, but because even very good people struggle inside a model designed to sell temporary projects to businesses they barely know. Agencies employ brilliant strategists, creatives, analysts and media specialists; the model simply gives them too little time to understand the problem and too many incentives to package the answer as a deliverable.


The ritual is familiar. A new agency arrives and asks to be briefed. The client tries to compress years of commercial history, customer knowledge, internal politics and previous mistakes into a deck. The agency turns that deck into a strategy, the strategy into a campaign and the campaign into a list of deliverables. When the season is over, it presents what it produced, reports the available numbers and demonstrates that the contract has been fulfilled.


Whether the business has actually become better at marketing is a much harder question, so it is usually postponed until the next planning cycle, when everyone starts again with another brief.


Nobody involved has to be incompetent for this to happen. It is simply what the conventional agency model is built to do: arrive, produce and leave. Unfortunately, marketing creates most of its value through a very different process. It has to stay, learn and compound.


The brief cannot carry the business

A brief is useful when it defines a task. We ask far too much of it when we expect it to transfer a company.


The knowledge an agency really needs is not waiting patiently in a folder called “Brand.” It is scattered across sales conversations, customer complaints, abandoned experiments, product decisions, support tickets and old arguments about pricing. Some of it has never been documented because nobody thought it mattered at the time. Some of it exists only in the memory of the employee who remembers why the apparently obvious idea failed two years ago.


Trying to capture all of this in a briefing document is not communication; it is compression. Nuance disappears first. A complicated buying committee becomes a persona, a commercial problem becomes a messaging problem, and an organization that has not agreed what it is selling asks an agency to find the right slogan for it.


The agency then does what the scope allows. It solves the simplified problem it was given, often with considerable skill. But the real problem may sit somewhere outside that scope: in the product, the sales process, the data, the customer experience or the decision nobody inside the company wants to revisit.


This is why the first campaign so often feels generic. It is not necessarily the product of lazy thinking; it is the product of shallow context. 


Marketing is a form of corporate memory

Good marketing grows out of accumulated understanding. A campaign puts a hypothesis into the market, customers respond in ways nobody fully predicted, sales hears objections that never appeared in the research, and the numbers raise better questions than the ones the team began with. The value lies not only in the result of that campaign, but in what the organization learns from it and carries forward.


Over time, those lessons become a capability. The company learns which customers are genuinely valuable, which claims create trust, which channels generate demand and which merely harvest it. It gets better at distinguishing a weak message from a weak offer, and at noticing when an apparently efficient campaign is attracting exactly the wrong people.


This capability is not a soft extra. It determines whether marketing becomes more intelligent over time or simply becomes more expensive. Companies do not become good at marketing because they occasionally buy good campaigns. They become good because they develop a reliable way to understand markets, make decisions and learn from the consequences.


Temporary project structures are poorly suited to building that kind of memory. A project team may learn a great deal, but those lessons disappear easily when the work ends, the account changes hands or the final presentation is filed away. Unless someone deliberately preserves and applies what was learned, the company forgets.


Seasonal agency work reproduces this problem perfectly. The campaign ends just as the useful questions begin.


Deliverables make excellent alibis

Because an agency cannot control the entire business outcome, it naturally reports the things it can verify: the campaign went live, the assets were delivered, the media budget was spent, and the agreed optimizations were made. None of that information is useless. It tells the client that work happened and the contract was respected.


It does not tell the client whether the work solved anything.


A campaign can deliver every promised asset while lead quality deteriorates. A channel can look efficient because it captures demand created elsewhere. The brand can become less distinctive at the same time as impressions rise, and the internal team can emerge from six months of activity without a single reusable insight. Yet the final report still has plenty to show, because the agency was contracted to produce marketing output, not to make the company better at marketing.


This is not a moral failure. It is an incentive problem. Visible work is relatively easy to price: hours, assets, campaigns and media plans all fit neatly into a statement of work. Capability, judgment and organizational improvement do not. So the contract gravitates toward the things both sides can count, even when those things are poor substitutes for meaningful progress.


So both parties retreat to the comfort of the measurable. The agency proves that it was busy; the client proves that it bought what procurement approved. The business problem, which is usually less cooperative, remains where it was.


The attribution theatre

Paying for results appears to solve the problem until someone has to determine which results the agency caused. That answer is often more precise than it is true.


Short measurement windows create a distorted picture. The entire cost of a campaign appears immediately, while some of its effects may emerge much later. At the same time, nobody should be allowed to hide weak work behind the mystical promise of “long-term brand building.” Serious accountability is necessary; false certainty is not.


The better approach is to treat measurement as an evolving body of evidence rather than a monthly verdict. That requires enough continuity to compare campaigns, refine assumptions, and understand why a metric changed. A temporary supplier is under pressure to show that this campaign worked. A long-term partner can ask the more useful question: what did this campaign teach us about how the business grows?


The expensive reset

Agency relationships frequently end at the moment they ought to become valuable. During the first months, the agency learns the language of the business, discovers which data can be trusted, and begins to understand why earlier decisions were made. Eventually, it can challenge the client intelligently rather than merely respond to the brief.


Then the account comes up for review.


Procurement asks for a pitch, leadership wants fresh thinking, or the agency rotates the team that acquired all that context. A new group arrives with new energy, new templates, and the same old questions. The company mistakes novelty for progress and pays for the learning curve again.


This reset is not harmless. It discards the trust and context that make a working relationship productive in the first place. Honest disagreement takes trust, useful judgment requires context, and neither can be manufactured during a chemistry meeting.


A long relationship is not automatically a good one, of course. Continuity without challenge becomes complacency. But the alternative to complacency is not permanent amnesia. It is a partnership that keeps the knowledge while continuing to question the decisions.


Build it in-house if you can

The cleanest answer is an internal marketing department. People inside the company hear the sales objections, watch customers leave, live with the consequences of positioning decisions, and remember what was tried before. Because they stay, they can connect a message tested in March with lead quality in June and a change in pricing six months later.


Not every business can build the department it needs, however. Senior marketing leadership is expensive, specialists are difficult to hire, and a growing company may need brand, performance, analytics, conversion, operations, and strategy long before it can justify filling all those roles individually. This is precisely the moment when many companies hire an agency, even though what they actually lack is not campaign capacity but a functioning marketing department.


The distinction matters. Capacity gives you more activity. A department gives that activity direction, connects it to the rest of the business, and ensures that every cycle leaves the organization more knowledgeable than it was before.


The outsourced marketing department

An outsourced marketing department is not simply an agency with a longer retainer. It accepts a different responsibility.


Instead of waiting for a brief, it begins with diagnosis: how the company grows, what customers value, where the commercial system breaks down, and which assumptions have never been tested. It connects marketing to sales, product, brand, data and internal decision-making because those connections determine whether a campaign can work at all.


Most importantly, it carries learning forward. Hypotheses are documented, results are interpreted in context, and decisions are remembered, so the next campaign begins where the last one ended rather than at zero.


That is the difference between a supplier and a partner. A supplier becomes more valuable when the client buys more supply; a partner becomes more valuable when the client becomes stronger. Reaching that point takes time because audience understanding, positioning, measurement, and organizational learning do not obey the campaign calendar.


Continuity is therefore not a pleasant extra. It is the mechanism through which marketing improves.


The Change Strategies position

At Change Strategies, we work as the outsourced marketing department: a performance partner that combines strategy and execution, stays close enough to understand the business and remains long enough to turn experience into capability.


That means we are not interested in filling a seasonal plan with activity merely because the budget exists. We want to know what the business is trying to change, what stands in the way, and what evidence would make the next decision better. Sometimes the answer is a campaign; sometimes it is clearer positioning, better customer research, a repaired measurement system or an uncomfortable conversation about the offer.


Our success cannot be reduced to how many assets we deliver. The more important test is whether marketing becomes more coherent, more accountable and more capable of producing predictable growth: whether the client understands its audiences better, makes stronger decisions and retains what has been learned.


Marketing is not a succession of projects performed around the edges of a company. It is a business system that becomes more valuable as its knowledge compounds. Most companies cannot build that system entirely in-house. They should not have to rent it either. 


Find a partner willing to build it with you and to stay long enough for the work to hold.
