Do your flagship products make the entire brand look competitive?
Schedule a meetingDiscover our pricing optimization softwareThe halo effect refers to the phenomenon whereby the price of a few iconic or highly visible products influences the perception of the entire brand’s pricing. If these key products appear inexpensive, the entire product line seems competitively priced, even if some products are more expensive. It is a strategy for building a reputation for competitive pricing without lowering the prices across the entire catalog.
The Essentials in 6 Questions
A few benchmark prices that shape perceptions of the entire product line.
Pricing, marketing, and sales management teams.
On an ongoing basis, with shopper studies to measure the impact.
For KVI products, typically 3 to 8% of the product line.
Buildthe price image while keeping costs under control and maintain margins elsewhere.
Identify key performance indicators (KPIs), align them strictly, and measure perception and sales.
Because customers remember only a few prices and judge the entire store based on them.
A retailer has priced 1,000 KVI products at the lowest price on the market: 78% of customers consider it “among the least expensive.”
Mass Retail · 30,000 SKUs in total
Some customers perceive the chain as "one of the least expensive, " even though its overall price index isn't particularly notable.
strictly aligned with the lowest price on the market
Margin maintained on the other 29,000 items
For the other 29,000 items, it maintains its normal policy, with a 3 to 5 point margin increase. Its overall price index, however, does not stand out in any particular way: it is the perception that has changed.
In three steps: identify the KPIs, align them strictly, and then verify perception and sales.
Identify the KPIs
The products that customers actively compare, often 3 to 8 percent of the product lineup.
Align exactly
An alignment policy specifically for these references.
Measuring the Effect
Shopper data cross-referenced with the real price index, traffic, and average basket size.
Our price optimization software identifies key performance indicators (KPIs) based on sales data and prioritizes tracking deviations from those indicators; our promotions management system measures the ripple effect of promotions on these flagship products. See also how to measure price elasticity beyond just the adjusted benchmark.
Poor KVI, a metric limited to the image itself, or confusion with bestsellers.
Short answers to the most frequently asked questions about the halo effect.
The halo effect refers to the phenomenon whereby the price of a product—often a flagship item or one that is highly visible—influences the overall perception of a retailer’s price image. If key products are perceived as inexpensive, the entire product lineup is perceived as competitively priced.
Customers remember only a limited number of prices and judge a retailer based on a few flagship products. Optimizing these prices improves the overall price image without having to adjust the entire product lineup.
The halo effect influences customer perception; cannibalization is an actual shift in sales between two products. One relates to perception, the other to purchasing behavior.
By cross-referencing consumer surveys, real price indices, sales data, and purchasing behavior, AI helps identify the products that have the greatest impact on consumer perception.

Faced with current market volatility, B2C pricing can no longer rely on intuition and instead requires a data-driven strategy. This analytical rigor makes it possible to adjust prices in real time to maximize profitability without sacrificing volume. A successful transition to this model offers profit growth potential of up to 9%.
Among the strategies tested, the psychological price point (€9.99) remains one of the easiest to implement.

Effective pricing management requires the rigorous integration of internal/endogenous data (costs, historical data) and external/exogenous data (competition, demand). This essential hybridization secures margins and objectifies trade-offs against market fluctuations. By structuring these signals, the organization transforms raw data into an operational profitability lever, deployable in practice in less than sixty days.

A price change results in both cannibalization (of substitute products) and the halo effect (on complementary products). Ignoring this mechanism is equivalent to measuring only half of the actual impact of a pricing decision.
On average, 22% of the increase in sales of a product on promotion comes from a simple shift from other SKUs in the same product line.
