In-store zones - hot, cold, high-traffic - directly determine the performance of your products on the shelf. A product that is well manufactured, well referenced and well negotiated - but misplaced - will not sell.
An operation involving theatrical displays generates an average of +85 % in additional sales, compared with +30 % without a display - the difference is entirely down to positioning and on-shelf activation. (source: La Compagnie des Images, Guide de la théâtralisation GMS 2026).
So the question is not just «Is my product on the shelf? - but »is it in the right place, in the right area?«
Reading a shop's zones means understanding how customers move around, anticipating their buying behaviour and placing your products where they are most likely to be seen, touched and bought. This is a fundamental skill for any sales or trade marketing manager who wants to turn their listing agreements into real sell-outs.
Warehouse zones: hot and cold zones, what are the differences?
The hot zone: the territory of natural visibility
In merchandising jargon, a hot zone is an area of the shop where footfall is naturally high. These areas catch the customer's eye as soon as they enter, encouraging quick purchasing decisions. They are generally located near the entrance, at the end of the main aisles, or near the checkouts - where impulse purchases are frequent.
For a brand, this is the place to secure as a priority for strategic products, new products or promotional items. This distinction also applies within a shelf: hot zones are located in the middle of the shelf and on the positive side, where impulse is most naturally triggered.
The cold zone: an under-exploited but not doomed area
A cold spot is the place where there is very little traffic in the shop - less accessible, less visible, often at the back of the surface or in the corners. But a cold spot is not irretrievably lost.
Placing must-have items in the cold zone forces customers to walk through the whole shop to get to them. This is known as the «loss leader» strategy - and supermarkets have mastered it perfectly.
This is precisely what supermarkets do with essential products - milk, flour, water - systematically positioned at the back of the shop to force customers to cross the entire shelf.
The customer journey: deciphering the invisible map
Understanding the zones is not enough without a vision of the customer flow - the path actually taken by shoppers from the entrance to the exit. There are several signals that can be used to assess this flow during a site visit:
- The natural direction of traffic (most shoppers in hypermarkets turn right to left after the entrance)
- Footprints and traces of wear and tear on the ground in the aisles
- The position of «typical shopping trolley» products that structure the usual itineraries
- Direct observation of shopper behaviour at peak times
Technology is now reinforcing this reading. Solutions such as Shoppertrack use infrared sensors to accurately measure traffic by zone, analysing traffic patterns and dwell times. This data is essential for confirming the effectiveness of existing hot zones and identifying new opportunities for optimisation.
What to look for first during a store check
A well-conducted blind check does more than just check whether the product is present. It involves reading the space as a whole before assessing the performance of your reference.
1. The general layout of the department
Where in the shop is your department located? Hot or cold zone? You may have the same amount of shelf space between two departments, but not the same visibility - and therefore not necessarily the same sales. This macro reading is often neglected. Yet it determines everything else.
2. The height of your products
The most strategic products should be placed at eye level (between 1.20 m and 1.60 m), the area where behavioural studies have shown they are most effective. The shelf can be read as a vertical hierarchy: eye level for priority references, hand level for everyday products, floor level for large capacities or low-margin private labels.
3. Share of shelf space and facing
The golden rule of supermarket merchandising : facing = sales. The more shelf space you occupy, the more you sell. Measure your LOS (shelf space share) and compare it to your category LOS. If your LOS is lower than your ROS, you are structurally under-represented in this outlet.
4. Legibility and signage
An effective on-shelf message must be understood in less than 3 seconds: a strong visual, a unique promise, a clear price. A missing or degraded POP message means a missed sales opportunity that neither the national negotiation nor the trade marketing budget can compensate for.
5. Out of stock
An empty facing is the worst signal a point of sale can send to a shopper. The fight against breakages is one of the most critical tasks of a well-trained field team. It must be systematically documented during every visit.
Zones and categories: adapting reading to the circuit
The zones do not apply in the same way to supermarkets, hypermarkets and DIY stores.
In supermarkets, The shopping journey is long, structured by the products in the typical shopping trolley. There are many cold zones, often corresponding to non-food sections or niche categories. The challenge is to capture shoppers outside their usual itinerary.
In GSS (high-tech, health and beauty, DIY), shoppers are more active and better informed. They often have a specific objective. The entrance area and product display areas play a key role. Theatrical displays and advice at the point of sale are becoming decisive factors in influencing the final choice.
DIY stores, Seasonality has a strong influence on hot zones. The flex zone - the area dedicated to seasonal products - is the one that will undergo the most changes throughout the year. Modular, easy-to-move displays are essential to maximise the versatility of these areas.
From reading to action: the levers that can be activated on the ground
Negotiating a better location
If your products are in the cold zone and your sell-out isn't taking off, this is a factual argument to make to the floor manager or shop director. A documented shelf survey, cross-referenced with DN and PDL data, builds a credible merchandising argument that facilitates negotiation.
Activating cold zones through dramatisation
A well-positioned sales promotion - tasting, demonstration, event corner - can transform a cold zone into a temporary focal point and generate additional traffic for products that are not naturally highly visible.
Adjusting the planogram
Systematically confront your planogram to the reality on the ground during each visit. The most successful retailers use digital planograms and indicators in near real time to constantly refine their layout and identify references that need to be repositioned or removed.
Reinforce cold zone signage
When used properly, POP and ILV can compensate in part for unfavourable positioning. Clear, legible and coherent information reassures customers, helps them to find their way without frustration and maintains their interest throughout their visit to the shop.
KPIs to monitor to manage performance by zone
The reading of the zones must be accompanied by precise indicators to measure the effectiveness of the actions taken. The most relevant to monitor :
| Indicator | What it measures | Why it's critical |
|---|---|---|
| Attendance rate (DN) | Presence confirmed on the shelf during the store check | The essential basis for all field monitoring |
| Share of linear (PDL) | Space occupied in cm or facings | To be compared with the PDM category |
| Breakage rate | Frequency of empty facings by sales outlet | Direct alarm signal on sell-out |
| Sell-out by zone | Actual sales by reference and by location | Validates or invalidates the implementation strategy |
| Turnover per m² | Profitability of allocated space | Key argument for negotiating a brand |
| Average basket / conversion rate | Impact of merchandising actions on the act of purchase | Measures the effectiveness of cold zone activations |
What a field expert can do for you
Reading a shop's zones is a skill that can only be acquired in the field, with method and regularity. An experienced salesperson, trained in merchandising techniques and shelf space analysis, will read a sales outlet in a few minutes with an acuity that cannot be replaced by data analysis alone.
It sees the shelf as the shopper sees it: standing up, on the move, with a basket and a mental list. It captures what an Excel table will never show - the collapsed gondola facing, the competitor's POS that visually crushes your reference, the loss leader positioned exactly where your customers pass by without ever looking to the right.
It is this intelligence on the ground, combined with detailed knowledge of the category, commercial agreements and the brand's objectives, that makes it possible to transform a shelf survey into an operational action plan. And this is precisely what specialist teams, regularly deployed across a defined number of points of sale, can bring to a brand seeking to improve its physical presence and its sell-out.
Conclusion
Reading a shop's zones means reading the customer's behaviour before they've even opened their wallet. Hot zones, cold zones, store height, traffic flow, signage, facing: each of these elements has a direct influence on the likelihood of a shopper seeing your product, stopping and buying it.
This is not just for merchandisers. It should be systematically read by any sales or trade marketing manager who wants to see his national agreements translated into real results at the point of sale.
