Purchase Decision Marketing: Stop Fishing Where the Fish Already Are

Purchase decision marketing is the practice of influencing how and why people choose one product or brand over another, across every stage of the decision-making process, not just the final click. Done well, it shapes preference before intent is declared, which is where most of the commercial leverage actually sits.

Most marketing budgets are weighted toward the bottom of the funnel, capturing decisions that have already been made. The more commercially interesting question is what moves people from indifference to consideration, and from consideration to commitment, before they ever search for a solution.

Why Most Marketers Are Solving the Wrong Problem

Early in my career, I was a performance marketing convert. I believed the data. I believed the attribution models. I believed that if you could see the click, you could own the outcome. We ran campaigns that looked exceptional on paper, and clients were happy because the numbers made sense in a spreadsheet.

What I underestimated, for longer than I should have, was how much of that performance was not performance at all. It was demand capture dressed up as demand creation. The people clicking our ads had already decided to buy something in that category. We were just the last brand they saw before they converted, and we were taking credit for a decision that was already made.

The analogy I keep coming back to is a clothes shop. Someone who has already tried something on is far more likely to buy it than someone who has never touched the fabric. The conversion rate looks great. But the work that actually drove that purchase, the brand awareness, the window display, the recommendation from a friend, happened long before they walked into the fitting room. Performance marketing often measures the fitting room and ignores everything that got the customer through the door.

This is not an argument against performance marketing. It is an argument for understanding what it actually does, and what it does not do. If you want to understand how growth strategy and go-to-market thinking connect to purchase behaviour, the Go-To-Market and Growth Strategy hub covers the broader commercial picture in more depth.

How Purchase Decisions Are Actually Made

There is a gap between how marketers model purchase decisions and how people actually make them. The funnel is a useful shorthand, but it implies a linearity that rarely exists in practice. People do not move neatly from awareness to consideration to purchase. They drift in and out of categories, they forget brands they once knew, they make decisions based on familiarity they cannot consciously explain.

What the evidence consistently points to, across categories and markets, is that mental availability matters enormously. When a purchase need becomes active, people do not conduct an exhaustive search. They think of the brands they already know. The consideration set is formed before the shopping starts. If your brand is not in that set, you are not competing, regardless of how good your product is or how well-optimised your paid search account is.

This has real implications for how budgets should be allocated. Forrester’s work on intelligent growth has long argued that sustainable growth requires building demand, not just harvesting it. The brands that consistently win market share tend to be the ones investing in broad reach and category-level associations, not just bottom-funnel efficiency.

I saw this play out clearly when I was running an agency and we had a client in a considered-purchase category, financial services, where the average time from first brand exposure to purchase was measured in months, sometimes years. Their instinct was to cut brand spend and double down on retargeting. It looked rational. It was not. They were shrinking the pool of future buyers while optimising the conversion of existing ones. Within eighteen months, their pipeline was thinner and their cost per acquisition had risen significantly because they were competing harder for a smaller audience.

The Three Moments That Actually Shape Purchase Decisions

Rather than thinking about the funnel as a linear process, it is more useful to think about the moments that genuinely move purchase decisions. There are three that matter most.

Category entry points

These are the situations, contexts, and triggers that prompt someone to start thinking about buying in a category. Thirst triggers a drink purchase. A broken appliance triggers a replacement search. A life event triggers a financial review. Brands that are strongly associated with these entry points are the ones that get considered first.

Most brands are far too narrow in how they think about category entry points. They focus on the obvious ones and ignore the peripheral triggers that represent significant volume. A brand that only associates itself with one or two entry points is leaving reach on the table. The brands that win across a category tend to own a broader set of these associations, built over time through consistent, contextually relevant communication.

The consideration shortlist

Once a need is active, most buyers form a shortlist of two to four brands before they start evaluating in earnest. This shortlist is largely driven by prior exposure and familiarity. It is not a rational process. It is a memory process. Brands that have invested in awareness and association over time tend to appear on more shortlists, which is the single biggest predictor of long-term market share.

The implication is uncomfortable for performance-focused marketers: you cannot buy your way onto a shortlist at the point of purchase. The work that earns a place on that shortlist happens months or years earlier, through brand-building activity that is genuinely difficult to attribute in a standard measurement framework.

BCG’s analysis of financial services go-to-market strategy makes a similar point in the context of financial products, where trust and familiarity built over time are more predictive of consideration than any single campaign or offer.

The final decision context

This is where performance marketing genuinely earns its place. Once someone is actively deciding, the quality of the product page, the clarity of the offer, the friction in the checkout process, and the presence of reassuring signals like reviews and guarantees all matter. This is the fitting room. And yes, it should be optimised.

But optimising the fitting room without filling the shop is a strategy with a ceiling. You are competing for a fixed pool of people who have already decided to buy in the category. Growth requires expanding that pool, which means reaching people before their need becomes active.

Why Companies Keep Getting This Wrong

The honest answer is that bottom-funnel activity is easier to measure, and measurement drives budget decisions. When I was judging the Effie Awards, one of the recurring tensions in the entries was between campaigns that had demonstrably moved brand metrics and campaigns that had produced clean, attributable short-term results. The latter often won internal budget battles even when the former had produced more durable commercial outcomes.

This is a structural problem in how marketing is evaluated, not a failure of individual marketers. When your CFO wants to see cost per acquisition and return on ad spend, it is very difficult to make the case for investment in activity that influences purchase decisions six months before they happen. The incentive structure pushes toward the measurable and away from the important.

There is also a deeper issue. Some companies use marketing to compensate for product and service problems that marketing cannot actually solve. If customers are not returning, if word of mouth is flat, if the product does not genuinely delight people, no amount of purchase decision optimisation will create sustainable growth. I have worked with businesses that were spending heavily on acquisition while their retention numbers quietly told a different story. The marketing looked good. The business was not growing. Those are not unrelated facts.

A company that genuinely delivers on its promises at every touchpoint, from first contact to post-purchase support, creates a compounding advantage that no media budget can fully replicate. Marketing is most powerful when it is amplifying something real, not compensating for something broken.

Vidyard’s analysis of why go-to-market feels harder than it used to touches on this tension: the proliferation of channels and measurement tools has made it easier to look busy and harder to know if you are actually moving the needle on purchase behaviour.

What a Purchase Decision Marketing Strategy Actually Looks Like

The practical implication of all of this is not to abandon performance marketing. It is to build a strategy that works across the full arc of the purchase decision, not just the final stage.

That means thinking seriously about reach. Not just reach as a vanity metric, but reach as a deliberate investment in future purchase consideration. Who are the people who will be in-market for your category in the next six to eighteen months? What are they thinking about now? What associations do you want them to have with your brand before they start actively looking?

It means thinking about category entry points with genuine rigour. Map the situations in which people start thinking about your category. Build creative and media strategies that associate your brand with those moments. This is not complicated in theory. It requires discipline and patience in practice, which is why many brands do not do it consistently.

It means being honest about what your measurement framework can and cannot see. Attribution models that give credit to the last click before conversion are not wrong, they are incomplete. They measure one moment in a longer process and present it as the whole story. Growth frameworks that treat acquisition as the only metric worth optimising tend to produce short-term results and long-term stagnation.

When I was scaling an agency from around twenty people to over one hundred, one of the things that became clear was that the clients growing fastest were not necessarily the ones with the most sophisticated performance marketing setups. They were the ones with clear positioning, consistent brand presence, and a genuine product advantage. The marketing was amplifying something real. The performance activity was converting demand that the brand had already created.

BCG’s work on the intersection of brand strategy and go-to-market execution makes the case that the most commercially effective organisations treat brand and performance as complementary, not competing, investments. That framing is still underused in most marketing planning conversations.

The Role of Content and Creators in Purchase Decisions

One area where purchase decision marketing has genuinely evolved is in the role of content and creator partnerships. People are increasingly forming opinions about brands and products through content they encounter outside of traditional advertising environments, in social feeds, in search results, in recommendations from people they trust.

This is not a new observation, but the commercial implications are still underappreciated. A well-placed piece of content or a credible creator endorsement can do more to move someone from indifference to consideration than a highly targeted paid ad, because it carries the weight of a recommendation rather than the friction of an advertisement.

Later’s research on creator-led go-to-market campaigns highlights how creator content performs differently from brand content in purchase decision contexts, particularly in the consideration phase where social proof and peer validation carry significant weight.

The mistake many brands make is treating creator partnerships as a performance channel, optimising purely for click-through and conversion. The more durable value is in the association and credibility that creator content builds over time. That is a brand-building investment with a long payback period, not a short-term acquisition tool.

Measuring What Matters Without Fooling Yourself

The measurement challenge in purchase decision marketing is real. Much of the activity that influences purchase decisions happens outside the view of standard analytics platforms. Brand awareness, category association, and consideration set membership are not visible in Google Analytics. They require different measurement approaches: brand tracking, survey-based research, share of search analysis, and long-term revenue trend analysis.

None of these are perfect. But the alternative, measuring only what is easy to measure and optimising toward it, produces a systematic bias toward short-term, bottom-funnel activity at the expense of the investments that drive long-term growth.

The honest position is that marketing does not need perfect measurement. It needs honest approximation and the intellectual humility to acknowledge that attribution models are a perspective on reality, not reality itself. The brands I have seen make the best long-term decisions are the ones that hold both views simultaneously: optimise what you can measure, and invest deliberately in what you cannot.

Hotjar’s work on growth loops and user feedback is a useful reminder that some of the most important signals about purchase behaviour come from qualitative data, from understanding why people chose you or did not, rather than from quantitative attribution alone.
