What are shopper insights?
Shopper insights are findings about the moment of purchase that change a decision you control. Research about shoppers that leaves your campaign exactly as it was is not an insight — it is a fact. Facts are useful. They are also cheap, and the change-a-decision part is what separates the two.
The textbook separation between shopper insights and consumer insights is about who is being studied: the person making the purchase decision versus the person who eventually uses the product. That distinction is real, and it costs money when a brand gets it wrong — we wrote about one version of that in the $200 gift card problem. But it is a distinction about inputs. The one that changes how you work is about outputs. Does this knowledge move a decision, or does it just sit in a deck? That is the question Bamboo Marketing puts to every insight deck that arrives ahead of a brief.
Who is the shopper data actually for?
Woolworths’ Cartology and Coles 360 have built large retail media businesses on the back of shopper data, and both keep expanding the surface area — Cartology completed a rollout of more than 1,600 retail media screens into health and beauty aisles during FY26, Mumbrella reported from the retailers’ results. Brands buy into those networks, and the reporting that comes back is a large part of what a category team now calls its shopper data.
Two things about that market deserve a strategist’s attention. The first is that growth is decelerating on both sides. Cartology’s year-on-year revenue growth fell from 19.5% to 7.8% in FY26, and Coles 360’s has declined every year it has been reported, from 27% in FY23 to 10% in FY26, according to Mumbrella’s analysis of both retailers’ FY26 results. Neither retailer reports the division’s revenue in its results.
The second is that the regulator took an interest in who the data is for. The ACCC’s supermarkets inquiry final report, published in March 2025, made twenty recommendations. The twentieth is that Coles and Woolworths “should be more transparent about how supplier funding contributions to their inhouse retail media services are used”. A separate recommendation asks the same pair to give loyalty program members periodic disclosure summaries.
Suppliers are helping to fund the data and, on the ACCC’s reading, do not always get an itemised account of what their contribution bought. Which makes the useful question for a brand or category team a different one. Not whether you have enough shopper data — you almost certainly do — but whether any of it has ever changed a decision.
Three filters for telling an insight from a fact
When we review an insight deck before a campaign brief gets written, three questions do most of the sorting. Findings that clear all three earn a place in the brief. The rest are context, which is a perfectly respectable thing to be.
1. Is it about the shopper, or the consumer?
“Our drinkers skew 25–34 and care about provenance” is a consumer statement. It is probably true. It tells you nothing about the person standing in front of a four-metre bay at 5:40pm with a trolley and a child in it. “In this category the shopper picks up two packs and puts one back” is a shopper statement, and it immediately raises a design question: what is on the pack that loses?
The test is whether the sentence survives being moved into the store. If it evaporates the moment you picture someone in an aisle, it belongs to the brand team rather than the shopper team.
2. Does it describe a moment, or an attitude?
Attitudes are stable, general and close to impossible to act on. Moments are specific, short and full of levers. “Shoppers want to reduce waste” is an attitude. “Shoppers buy the larger format when the unit price is on the ticket and the smaller one when it isn’t” is a moment, and it points straight at a piece of point-of-sale you can change this quarter.
This is why we keep coming back to the 3-Second Equation. If the shopper’s decision is a quick weighing of reward and belief against friction, a usable insight tells you which of those three terms is the one that is broken. An insight that doesn’t name a term is a mood board.
3. Does it point at a lever you actually hold?
Plenty of genuinely interesting shopper research points at something the brand does not control — shelf position, base price, the retailer’s own range decision. That research has a use; it is an argument to take to the retailer, not a campaign brief. An insight you can act on points at the mechanic, the reward, the pack, the message at the fixture, or the case you put to the category buyer.
When a finding fails this filter, the honest move is to say so in the room rather than designing a promotion around something you cannot influence.
What a real shopper insight changes
Three decisions, in our experience, and the order matters because each one narrows the next.
It settles the objective. A good insight makes it obvious whether the campaign is here to win trial, frequency, basket, data or loyalty, which is the discipline behind the One Job Rule. Campaigns get kitchen-sinked when nobody has a strong enough read on the shopper to choose, so the objective defaults to all of them.
It sets the reward type. Once the job is fixed, knowing whether the shopper in this category arrives in a hopeful frame or a careful one determines whether you are designing a draw or a cashback, which is the whole of Hope vs. Greed. That is a judgement about a moment, and it is exactly the judgement attitudinal research cannot make for you.
It gives you something to say to the category manager. With the job and the reward settled, you still have to get the thing approved by the buyer, and the buyer does not want your brand’s insight. They want a category insight — something that makes their aisle work harder, expressed in their language. That is the raw material for the S.O.S. framework, and it is the most common thing missing from a promotion that gets knocked back.
Where the good ones tend to come from
Panel data, loyalty extracts and retail media reporting are all buyable, which means your competitors can buy them too. The insights that change a campaign tend to come from three less glamorous places.
Store visits, done properly. Not a walk-through with the client, but forty-five minutes standing near a fixture during a trading peak, counting. The ACCC’s supermarkets inquiry found that convenience is a key determinant of where Australians shop, even as more of them compare prices and shop around. That tension between habit and hunting is visible in a real aisle and almost invisible in a survey, which is why Bamboo Marketing books store time into a campaign timeline rather than hoping someone finds an afternoon.
The retailer’s objection. When a category manager says no, the reason they give is usually a shopper insight in a bad mood. It is free, it is specific, and it comes from someone who looks at that aisle’s numbers every week.
Your own last campaign. The redemption curve, the entry drop-off, the moment the volume stopped — that is first-party shopper behaviour nobody else has. Reading it while a campaign is still running rather than in the post-analysis is an execution capability, and it is where Trevor Services picks up the story. Their 2026 Australian promotion benchmarks are a reasonable place to check whether what you saw was normal for the mechanic.
The test, in one question
Before the next insight deck goes into a campaign brief, take each finding and ask what you would do differently if it turned out to be false. If the answer is nothing, it was never load-bearing. Cut it.
What survives that question is usually two or three findings, and they are the ones worth arguing over — with the brand team, with the agency, and eventually with the buyer. The rest was research, which is a different and less expensive thing than insight.
Rethinking how shopper insight feeds promotional planning is usually where a campaign conversation with Bamboo Marketing starts. If that is where you are, we’d welcome the conversation.
