The Customer Journey Funnel Is Lying to You

The customer experience funnel is one of marketing’s most useful frameworks and one of its most abused. At its best, it maps how people move from awareness to purchase and gives teams a shared language for thinking about where to invest. At its worst, it becomes a justification for ignoring the top of the funnel entirely and pouring budget into the bottom, where the numbers look clean and the attribution is easy.

Most organisations do not have a funnel problem. They have a funnel interpretation problem.

What the Customer experience Funnel Actually Represents

The funnel model, in its simplest form, describes a population of people narrowing as they move through stages: awareness, consideration, intent, purchase, and retention. The logic is straightforward. Not everyone who hears about your brand will consider it. Not everyone who considers it will buy. Not everyone who buys will return.

Where marketers go wrong is treating the funnel as a fixed pipeline rather than a dynamic, leaky, non-linear system. Real customers do not move neatly from stage to stage. They enter at different points, loop back, go cold for months, and convert after a trigger that has nothing to do with your last retargeting ad. The customer experience is messier than any model suggests, and the funnel is a simplification worth using, not a truth worth defending.

I spent a significant part of my early career in performance marketing, managing large budgets across paid search and paid social. The metrics were compelling. Cost per acquisition, return on ad spend, conversion rates. All clean, all trackable, all pointing in the right direction. What I did not fully appreciate at the time was how much of that performance was capturing demand that already existed, rather than creating it. We were fishing in a pond that someone else had stocked.

If you are interested in how customer experience thinking connects to funnel strategy more broadly, the Customer Experience hub on The Marketing Juice covers the full landscape, from measurement to culture to ownership.

Why Brands Systematically Over-Invest in the Bottom of the Funnel

This is not a new observation, but it remains stubbornly relevant. Lower-funnel activity is measurable in ways that upper-funnel activity is not. When someone clicks a search ad and converts, the attribution model assigns credit. When someone sees a brand campaign six months earlier and files your name away as a credible option, nothing gets logged. The brand campaign looks expensive and inefficient. The search ad looks like a bargain.

The result is a slow gravitational pull toward the bottom of the funnel, where the numbers are comfortable and the story is easy to tell in a board meeting. Over time, brands find themselves spending almost entirely on people who were already looking for them. Conversion rates stay healthy. Revenue plateaus. Nobody connects the two.

I saw this pattern clearly when I was running a performance agency. We were delivering strong results by every metric the client cared about. But when we looked at the actual customer data, the brand was not reaching new audiences at any meaningful scale. It was cycling through the same pool of in-market buyers, converting them efficiently, and calling it growth. It was not growth. It was harvest.

The analogy I keep coming back to is a clothes shop. Someone who picks something up and tries it on is dramatically more likely to buy than someone who walks past the window. Lower-funnel activity is brilliant at capturing the people who are already in the fitting room. But if nobody is walking through the door, the fitting room is empty. Upper-funnel investment is what fills the shop.

The Awareness Stage: Where Growth Actually Begins

Awareness is the stage most brands undervalue and most CFOs want to cut first. It is also the stage that determines whether your funnel has any future at all.

Effective awareness activity does two things. It reaches people who do not yet know they need what you offer, and it builds the mental availability that makes your brand come to mind when a purchase occasion arises. Neither of these outcomes shows up cleanly in a last-click attribution model, which is why awareness budgets are perennially vulnerable.

The question worth asking is not “what is our cost per impression?” but “are we reaching people who are not already in our customer base?” If your audience targeting is tight enough that you are only ever talking to existing customers and warm prospects, you are not doing awareness. You are doing expensive retention.

Tools like digital optimisation frameworks can help teams think more rigorously about how to connect upper-funnel activity to downstream outcomes, even when the direct attribution is imperfect. The goal is not perfect measurement. It is honest approximation.

The Consideration Stage: Where Most Brands Lose the Argument

Consideration is where a potential customer is actively weighing options. They know they have a problem. They know solutions exist. They are deciding which one is right for them.

Most brands treat this stage as a content problem. More case studies, more comparison pages, more testimonials. That is not wrong, but it misses the more fundamental question: are you actually making a compelling case, or are you just producing content?

When I was judging the Effie Awards, the work that stood out at the consideration stage was not the work with the most information. It was the work that understood what the customer was actually anxious about and addressed it directly. The best consideration-stage marketing reduces uncertainty. It does not add to it with more features and claims.

The practical implication is that consideration-stage content should be built around customer objections, not product benefits. What are the three reasons people do not buy from you? Address those, clearly and honestly, and you will convert more people than any feature comparison table will.

Understanding how customers experience the consideration stage also requires decent analytics. Customer experience analytics can surface where people are dropping off, what content they are engaging with, and which touchpoints are actually influencing decisions, rather than just the ones that get credit in the attribution model.

The Purchase Stage: Where Friction Kills Conversion

By the time someone reaches the purchase stage, you have largely won the marketing argument. They have decided they want what you offer. The question is whether your purchase experience lets them follow through or gets in the way.

Friction at the purchase stage is a commercial problem masquerading as a UX problem. Complicated checkout flows, unclear pricing, unexpected costs at the final step, account creation requirements that nobody asked for. These are not design failures. They are business failures, and they are surprisingly common in organisations where marketing and product teams operate in separate silos.

I worked with a client whose conversion rate on their e-commerce site was notably below industry norms. The marketing team kept proposing more spend to drive more traffic. When we actually looked at the purchase funnel in detail, roughly 40% of people who added an item to their basket abandoned at the payment page. More traffic would have made the problem bigger, not smaller. The fix was operational, not promotional.

This is a pattern worth watching. Marketing is often deployed as a blunt instrument to prop up problems that sit elsewhere in the business. If the purchase experience is broken, no amount of upper-funnel investment will fix the underlying economics.

Post-Purchase: The Stage That Determines Whether the Funnel Pays Back

Most funnel models end at purchase. That is a significant mistake, particularly for businesses where customer lifetime value is the actual unit of commercial success.

The post-purchase stage is where the brand promise either holds or collapses. A customer who buys and has a good experience is more likely to buy again, more likely to recommend the brand, and less sensitive to price on their next purchase. A customer who buys and has a poor experience is not just lost. They are often actively damaging, particularly in the age of review platforms and social media.

Retention is not a separate strategy from acquisition. It is the same funnel, extended. And it is almost always cheaper to retain a customer than to acquire a new one, which means every pound spent on post-purchase experience has a different return profile than a pound spent on awareness. Neither is wrong. Both need to be in the plan.

Channels like SMS, when used with genuine relevance rather than as a broadcast tool, can be effective at maintaining engagement post-purchase. SMS customer engagement works best when it feels like a service rather than a promotion. The moment it feels like spam, it erodes the relationship it was supposed to strengthen.

Teams looking to develop stronger skills in managing post-purchase relationships often benefit from structured approaches to customer service training, particularly around how frontline staff handle complaints and escalations. The experience a customer has when something goes wrong tells them more about a brand than anything that happens when everything goes right.

How to Diagnose Where Your Funnel Is Actually Breaking

Most funnel audits focus on conversion rates at each stage. That is a reasonable starting point, but it misses the more important question: what is causing the drop-off between stages?

There are three common culprits. First, a mismatch between the message at one stage and the experience at the next. If your awareness campaign promises simplicity and your website is complicated, people will leave. The funnel is not broken. The handoff is broken.

Second, targeting that is too narrow at the top and too broad at the bottom. This is the inverse of what most brands want. They reach a small, qualified audience with brand activity and then retarget the entire internet at the purchase stage. The economics rarely work.

Third, a measurement model that rewards the wrong behaviour. If your team is incentivised on last-click conversions, they will optimise for last-click conversions, regardless of what is actually driving growth. The metric shapes the strategy, whether you intend it to or not.

Tools like AI-assisted experience mapping are becoming more useful for identifying where customers are getting stuck, though they are still a perspective on the data rather than a definitive answer. The value is in the questions they surface, not the conclusions they draw.

The Measurement Problem Nobody Wants to Admit

Funnel measurement is genuinely hard, and the industry has not been honest enough about that. Last-click attribution is wrong. Multi-touch attribution is less wrong but still wrong. Media mix modelling is expensive and slow. Incrementality testing is the most reliable approach for individual channels but cannot easily account for the interaction effects between them.

The honest answer is that no measurement model will give you a complete picture of how your funnel is working. What you can do is use multiple approaches, triangulate, and make decisions based on honest approximation rather than false precision.

I have sat in too many client meetings where the conversation was entirely about optimising the attribution model rather than asking whether the underlying strategy was sound. Attribution is a lens. It is not the strategy. Confusing the two is one of the more expensive mistakes a marketing team can make.

The broader question of how to measure what actually matters across the customer experience is something I explore throughout the Customer Experience section of The Marketing Juice. Funnel measurement sits inside a larger set of decisions about what you are trying to understand and why.

What a Well-Functioning Funnel Actually Looks Like

A well-functioning customer experience funnel has a few characteristics that are easy to describe and surprisingly rare to find in practice.

It reaches genuinely new audiences at the top, not just recycling existing demand. It maintains a consistent message and experience as people move between stages. It removes friction at the purchase point rather than adding to it. And it treats the post-purchase relationship as a commercial priority, not an afterthought.

It also has a measurement approach that is honest about its limitations. Teams that claim to know exactly which touchpoint drove every conversion are either using a model that flatters their existing spend, or they are not being straight with you. Probably both.

The brands that get this right tend to share one characteristic: they have a genuine product or service that customers value, and the funnel is built to communicate and deliver that value consistently. Marketing cannot manufacture a good customer experience. It can reflect one. If the experience is weak, the funnel will always underperform, regardless of how much is spent on it.

That is a point I keep returning to across twenty years in this industry. The most effective marketing I have ever seen was built on top of something genuinely worth buying. The least effective was trying to compensate for something that was not.
