Marketing Plans That Don’t Gather Dust

A marketing plan is only useful if it connects to how a business actually grows. Most don’t. They describe activity, not direction. They list channels and budgets without explaining why those choices were made or what the business needs to be true for any of it to work.

Preparing a marketing plan well means working backwards from commercial outcomes, making explicit assumptions about your market and your customers, and building in enough flexibility to adapt when reality disagrees with your forecast. That’s harder than it sounds, and most plans skip the difficult parts.

Why Most Marketing Plans Fail Before They Launch

I’ve reviewed a lot of marketing plans over the years, both as an agency CEO and as a client-side advisor. The ones that failed most predictably shared a common trait: they were written to satisfy a stakeholder, not to guide a team. They looked thorough. They had the right sections. They contained charts and channel breakdowns and quarterly milestones. And they were largely ignored by March.

The problem usually wasn’t the format. It was that the plan had no clear theory of growth sitting underneath it. No one had asked the hard question: what does this business need to be true about its market for this plan to work? Without that, every channel choice is arbitrary. You’re not making strategic decisions. You’re filling in a template.

If you’re thinking about marketing planning in the context of a broader go-to-market build, the articles in the Go-To-Market and Growth Strategy hub cover the commercial foundations that sit underneath any effective plan.

Start With the Commercial Problem, Not the Marketing Brief

Before you open a slide deck or a planning spreadsheet, you need to be clear on what the business is actually trying to solve. Not the marketing objective. The business problem.

Is revenue flat because you’re losing existing customers faster than you’re acquiring new ones? Is the pipeline healthy but conversion is poor? Are you winning in one segment and invisible in three others that represent most of the market? These are different problems. They require different plans. Treating them as a single “grow the brand” brief produces plans that do a little of everything and not enough of anything.

Early in my career I spent a lot of time optimising lower-funnel performance. We got good at capturing intent. Click-through rates improved, cost-per-acquisition fell, and the dashboards looked excellent. What I didn’t appreciate then was how much of that performance was capturing demand that already existed. The moment a competitor invested in building new demand upstream, our numbers started to soften. We hadn’t grown the market. We’d just been efficient at harvesting it.

A good marketing plan has to answer: where is the growth actually going to come from? Existing customers buying more? Lapsed customers returning? New audiences who don’t know you yet? Each of those requires a fundamentally different approach. Most plans try to address all three simultaneously with a budget that could only do one of them properly.

The Sections That Actually Matter

There’s no single correct structure for a marketing plan. But there are sections that, in my experience, determine whether a plan is genuinely useful or just a document that gets filed.

Situation Analysis: What’s Actually True Right Now

This is where most plans either go too shallow or too deep. Too shallow and you’re working from assumptions that haven’t been tested. Too deep and you spend six weeks writing a situation analysis that nobody reads and you’ve run out of time before the planning actually starts.

What you need from a situation analysis is a clear-eyed view of three things: where the business is winning and why, where it’s losing and why, and what’s changing in the market that will affect both. That last one is the one teams most often skip. They document the present without asking what’s likely to be different in twelve months.

Tools like Hotjar’s feedback and behaviour analytics can help fill in the gaps that your CRM and web analytics leave, particularly around why customers behave the way they do rather than just what they do. That qualitative layer matters more than most plans acknowledge.

When I was running an agency turnaround, one of the first things I did was stop looking at the agency’s own marketing metrics and start talking to the clients we’d lost. Not surveys. Conversations. What I heard was almost entirely absent from the existing situation analysis. The data said our retention was declining. The conversations told us why, and the answer wasn’t what anyone had assumed.

Audience Definition: Beyond the Persona

Most marketing plans include a customer persona section. Most of those personas are useless. They describe demographics and job titles rather than the problem the customer is trying to solve and the alternatives they’re considering when they don’t choose you.

The question your audience definition needs to answer is: who are we trying to reach that we’re not currently reaching, and why aren’t we reaching them? That’s a harder question than “who is our target customer,” but it’s the one that drives growth.

There’s a useful framing I’ve come back to repeatedly over the years. Someone who has already tried your product or engaged seriously with your brand is far more likely to convert than someone who has never encountered you. The implication isn’t that you should only market to warm audiences. It’s that your plan needs to include a deliberate strategy for creating that familiarity at scale, not just capturing it once it exists. Go-to-market has become harder partly because buyers are more saturated with messaging and less willing to engage with brands they haven’t encountered before. Building familiarity before the sales moment isn’t a nice-to-have. It’s the work.

Objectives: Specific, Commercial, and Honest

Marketing objectives should be derived from business objectives, not invented alongside them. If the business needs to grow revenue by 20% in the next financial year, your marketing objectives should connect directly to that number. How many new customers does that require? What does average order value need to look like? What’s the retention rate assumption baked into that forecast?

When objectives are set in isolation from the commercial model, you end up with plans that hit every marketing KPI and miss the revenue target. I’ve seen this happen repeatedly. The team celebrates record engagement while the CFO is asking why revenue is flat. The problem isn’t measurement. It’s that the wrong things were being measured from the start.

BCG’s work on aligning marketing and commercial strategy is worth reading if you’re trying to build a tighter connection between your plan and the P&L. The argument that marketing should be embedded in commercial planning rather than downstream of it is one I’ve held for most of my career.

Budget Allocation: Make the Trade-offs Explicit

Budget allocation is where most plans become dishonest. Not deliberately, but by omission. The numbers get presented as a fait accompli without showing the logic that produced them. Why is 40% going to paid search? Why is brand activity funded at that level and not higher or lower? What’s the assumption about how long it takes for brand investment to show up in commercial results?

Making those trade-offs explicit is uncomfortable because it invites challenge. But it’s also what separates a plan from a budget request. A plan explains why the money is allocated the way it is. A budget request just asks for it.

I’ve managed hundreds of millions in ad spend across thirty-odd industries. The most consistent mistake I’ve seen isn’t overspending or underspending. It’s spending without a clear theory of return. Teams allocate budget to channels because they’ve always used them, or because a competitor is visible there, or because someone senior has a preference. None of those are good reasons. The question is always: what does this spend need to do, and how will we know if it’s doing it?

Forrester’s intelligent growth model offers a useful lens here, particularly around how to think about the relationship between investment, market position, and commercial return across different stages of business maturity.

Channel Strategy: Why, Not Just What

The channel section of most marketing plans reads like a list. Paid search. SEO. Email. Social. Events. Each with a budget line and some activity descriptions. What’s usually missing is the reasoning. Why these channels? What role does each one play in the customer experience? How do they connect to each other?

Channel selection should follow audience and objective, not convention. If your audience isn’t on LinkedIn, spending on LinkedIn because it’s a B2B norm is wasted money. If your objective is to reach audiences who don’t know you exist, doubling down on retargeting is the wrong answer. It feels productive because the metrics are good, but you’re talking to people who already know you.

The go-to-market challenge many teams face is that they’ve built efficient systems for reaching existing demand and have no real capability for creating new demand. Vidyard’s research on untapped pipeline potential points to this gap directly: most GTM teams are leaving significant revenue on the table because their motion is almost entirely inbound and intent-led, with little investment in the earlier stages of awareness and consideration.

The Assumptions Section Nobody Writes

This is the section I’d make mandatory if I were setting the standard for marketing plans. Every plan rests on a set of assumptions. Market conditions will remain broadly stable. Conversion rates will hold. The competitive landscape won’t shift dramatically. Customer acquisition costs won’t spike. Most plans don’t write these down. They’re implicit, which means nobody challenges them and nobody notices when they’re wrong until the results start to disappoint.

Writing your assumptions down does two things. It forces you to think clearly about what your plan depends on. And it gives you a structured way to review the plan mid-year. If the results aren’t tracking, you can go back to the assumptions and identify which ones have broken down. That’s a much more useful conversation than “why isn’t the plan working?”

When I was building out a new market entry strategy for a client in a sector I hadn’t worked in before, I spent more time on the assumptions section than any other part of the plan. We listed every belief we were relying on, from category growth rates to customer acquisition timelines to competitive response. About a third of them turned out to be wrong within six months. But because we’d written them down, we could adapt quickly rather than defending a plan that no longer reflected reality.

Measurement: Honest Approximation Over False Precision

Marketing measurement is genuinely hard, and most plans either overclaim or underclaim. Overclaiming looks like attribution models that credit marketing with every conversion regardless of what else was happening. Underclaiming looks like refusing to measure brand activity at all because it’s “too difficult.”

What a good marketing plan needs is a measurement framework that’s honest about what can be measured directly, what can be approximated, and what can only be inferred. That’s not a failure of rigour. It’s an accurate description of how marketing works.

I spent time judging the Effie Awards, which are explicitly focused on marketing effectiveness. The work that stood out wasn’t the work with the most sophisticated attribution. It was the work where the team had been honest about what they were trying to achieve, had measured the right things, and could show a credible connection between the marketing activity and the business outcome. That connection doesn’t have to be mathematically perfect. It has to be defensible.

Forrester’s perspective on go-to-market execution challenges, while focused on a specific sector, raises questions about measurement and attribution that apply broadly. The difficulty of connecting marketing activity to commercial outcomes isn’t a new problem. It’s a structural one that requires honest frameworks rather than more sophisticated tools.

How to Make a Plan That Gets Used

The best marketing plans I’ve seen have a few things in common. They’re short enough to be read. They’re specific enough to be acted on. And they’re honest enough to be trusted.

Length is not a proxy for quality. A forty-page marketing plan that nobody reads is less useful than a ten-page plan that the whole team can handle. If your plan requires a guided tour to understand, it’s too complicated. The people who need to execute it won’t carry forty pages in their heads. They’ll default to habit, which means the plan won’t change anything.

Specificity matters more than comprehensiveness. A plan that says “we will invest in content marketing to build organic traffic” is less useful than one that says “we will publish two long-form articles per month targeting these three keyword clusters, with the objective of ranking in the top five for these specific terms within twelve months.” The second version can be acted on. The first is a statement of intent.

And honesty matters more than either. A plan that overpromises to get budget approved, or that underestimates the competitive challenge to keep stakeholders comfortable, is setting the team up to fail. The plan should reflect what you actually believe, including the parts that are uncertain.

BCG’s analysis of go-to-market planning in high-stakes launch environments is a useful reference point for the discipline required when the cost of a poor plan is high. The principles translate well beyond the sector: clarity of objective, explicit trade-offs, and a realistic view of what the market will and won’t respond to.

Marketing planning sits at the intersection of commercial strategy and execution. If you want to build a stronger foundation for how your plan connects to business growth, the Go-To-Market and Growth Strategy hub covers the strategic frameworks that sit underneath the planning process.
