What if a brand’s success wasn’t just shaped by what customers see or hear, but by what they smell? Long regarded as a “sensory add‑on,” olfactory marketing has become a powerful strategic tool with measurable returns. According to the Scent Marketing Institute (2021), a scented environment can increase perceived quality by 42% and extend customer dwell time by up to 20%.
At ECO.FRENCH.LAB, we have specialized for over a decade in creating custom olfactory signatures that go beyond ambiance — transforming spaces into emotional experiences that drive customer loyalty, brand identity, and measurable ROI.
When emotions drive business growth
The sense of smell is uniquely linked to memory and emotion. The right fragrance can trigger a memory, spark desire, and strengthen brand loyalty. That’s why olfactory marketing has become a powerful tool for brand differentiation. According to the Journal of Marketing Research (2022), sales increase by an average of 11% in retail spaces that diffuse a consistent olfactory signature. In the hospitality sector, a Hilton study (2023) found a 45% increase in revenue in scented environments.
These numbers aren’t anecdotal — they prove that scent influences purchasing behavior, brand perception, and customer retention.
Case study: An olfactory signature that delivers ROI
A major international hotel group partnered with ECO.FRENCH.LAB to design a bespoke olfactory signature to elevate its premium brand experience. For a total investment of approximately €38,000 (creation, equipment, diffusion), the results after one year were exceptional:
+28% customer satisfaction
+35% recommendations
€180,000+ additional revenue
ROI of over 320% in the first year
This demonstrates how a tailored olfactory strategy delivers both emotional and financial value.
Scent marketing as a conversion driver in retail
The impact of olfactory marketing extends to retail. A 200 m² premium fashion boutique collaborated with ECO.FRENCH.LAB to create a subtle scent experience aligned with its brand identity. After implementation:
Visit duration increased by 50% (12 to 18 minutes)
Conversion rate grew from 8% to 12%
Average basket value rose from €85 to €115
Customer loyalty increased by 40%
These findings echo the Nielsen Sensory Branding Report (2023), which shows brands that integrate scent into the customer journey experience a 30% higher retention rate than the average.
