Is the gap between your private-label brands and the leading brands remaining stable?
Schedule a meetingDiscover our product matching solutionHorizontal price linking ties the price of a product to thatof other equivalent products in the same category: two brands of plain yogurt, two power drills with similar features, a national brand and its private label. It maintains consistent price differentials between substitutable products.
The Essentials in 6 Questions
A price relationship between substitutable products within the same category.
Pricing teams and category managers.
With every price change in the leading benchmark.
Between a national brand and a store brand, or between competing brands in the same aisle.
Keep the offering clear and avoid cannibalization.
Ratios (rather than fixed margins) applied automatically.
Because a stable price difference between substitutable products shapes the customer's purchasing decision.
When the leading brand's price increases from €1.89 to €1.99, its two private-label products are adjusted by the same percentage.
Pasta aisle · leading brand, national private label, entry-level private label
Price increase for the leading brand (€1.89 → €1.99), due to higher material costs.
National private label, ratio maintained (€1.29 → €1.35)
Entry-level private label, price ratio maintained (€0.89 → €0.94)
The rule: National private label = market leader × 0.68 and entry-level private label = market leader × 0.47. The national private label automatically increases from €1.29 to €1.35, and the entry-level private label from €0.89 to €0.94: the perceived price gaps remain stable.
By identifying the actual substitutes and then setting the ratios applied by the pricing engine.
Substitutable SKUs are identified by their attributes (use, format, value proposition), which requires reliable product matching (see competitive monitoring and product matching). Our solution for product matching, cloning, and chaining then applies the rules automatically. The choice of target price differentials between brands depends on your pricing strategy. To link product lines together, see vertical chaining.
Fake substitutes, discrepancies in euro amounts, or too many rules piled on top of each other.
Short answers to the most frequently asked questions about horizontal chaining.
Horizontal price linking ties the price of one item to that of other equivalent items within the same category, typically among substitutable products: two brands of plain yogurt, two similar hole punches, or two colors of the same textile item.
Horizontal linking connects substitutable products at the same level (competing brands, private labels, and national brands). Vertical linking connects the different tiers within the same product family (entry-level, mid-range, and premium).
It's more of a ratio: a fixed difference in euros loses its meaning when prices change, whereas a ratio preserves the perceived difference.
A clearer pricing structure, less unintended cannibalization, and management based on coherent product families rather than on an item-by-item basis.

Product matching or linking is the foundation of competitive monitoring, as it prevents the comparison of non-equivalent products. Reliable matching safeguards margins by basing repricing on actual, multi-signal data.
Key finding: According to the Diamart study, 50% of French retailers still consider this challenge to be unresolved.
These similarity algorithms rely heavily on natural language processing (NLP) to match the descriptions of different products.

A high-performing pricing organization relies on clear governance and a hybrid model, combining central strategy with local agility. By structuring precise roles such as Pricing Analyst or Head of Pricing via a RACI matrix, the company secures its margins and competitiveness. This operational rigor transforms pricing into an immediate and sustainable profitability lever.
Structuring this governance is precisely the role of BOOPER's Operational Pricing Consulting module.

Effective pricing management relies on a constant balance between margin, competitiveness, and price perception. By monitoring five categories of key performance indicators, you can safeguard your profitability while remaining attractive to customers. A mere 1% increase in price realization can boost operating profit by 6.4%, transforming your pricing strategy into a major driver of growth. Building and equipping this KPI dashboard is the purpose of BOOPER’s Price Diagnostic module.
