Reading time: 8 minutes
Did you know that 75% of our daily emotions are influenced by smell?

It’s no coincidence. It’s scent marketing.
In this article, you’ll discover exactly what scent marketing is, how it works in the brain, why it increases sales by up to 40%, and how you can implement it in your business, whatever your industry.
What Is Scent Marketing?
Definition
Scent marketing (also called aromarketing or scent branding) is the technique of using scents strategically to:
- Create a brand identity
- Influence purchasing behaviour
- Create memorable memories
- Improve the customer experience
- Increase time spent
- Increase average order value
It’s not simply about "using an air freshener". It’s strategic scent architecture.
A Brief History
1960s: First studies on smell and memory
1980s: Disney begins using scents in attractions (the smell of popcorn on Main Street)
1990s: Singapore Airlines creates its signature scent, "Stefan Floridian Waters"
2000s: Abercrombie & Fitch makes Fierce part of its brand strategy
2010s: The scent marketing boom. Major brands create dedicated departments
2020s: Democratisation. Small businesses gain access to professional technology
The Science of Smell: Why It Works
The Brain–Smell Connection
Smell is the only sense DIRECTLY connected to the limbic system (the emotional centre of the brain).
Olfactory pathway:
- Aromatic molecules enter through the nose
- Olfactory receptors detect them
- The signal goes directly to the amygdala (emotions) and hippocampus (memory)
- It does NOT pass through the thalamus (rational filter)
Result: Scents trigger immediate emotional responses before you rationalise them.
Olfactory Memory: The Proust Effect
Writer Marcel Proust described how the smell of a madeleine instantly transported him back to his childhood.
Scientific data:
- We remember 35% of what we smell
- We remember only 5% of what we see
- Olfactory memories last longer than visual or auditory ones
- A smell can evoke a memory from 20 years ago with absolute clarity
That’s why smelling an ex’s perfume instantly takes you back to that moment.
Impact on Purchasing Behaviour
Scientific studies show:
Rockefeller University study:
- We remember 1% of what we touch
- 2% of what we hear
- 5% of what we see
- 15% of what we taste
- 35% of what we smell
Journal of Retailing study: Scented environments increase:
- Time spent: +40%
- Purchase intent: +20%

How to Implement Scent Marketing in Your Business
Step 1: Define Your Goal
What do you want to achieve?
- Increase sales
- Create a brand identity
- Improve the customer experience
- Reduce perceived waiting time
- Neutralise bad odours
Your goal determines the strategy.
Step 2: Get to Know Your Customer
Key questions:
How old is your average customer?
- Young people (18–30): Modern, sweet, energetic scents
- Adults (30–50): Sophisticated, balanced scents
- Older customers (50+): Classic, understated scents
What kind of lifestyle do they have?
- Sporty: Fresh, citrus scents
- Corporate: Elegant, serious scents
- Bohemian: Natural, herbal scents
Step 3: Choose Your Scent Strategy
Option A: Functional Scent Goal: Solve a problem (bad odours, stuffy atmosphere) Scents: ODOUR NEUTRALISER, AQUA, GREEN TEA
Option B: Ambient Scent Goal: Create a pleasant atmosphere without standing out Scents: AQUA, GREEN TEA, APPLE
Option C: Signature Scent Goal: Memorable brand identity Scents: PERFUME #6 FIERCE, AMATISTA, PERFUME #3 MIYAKE
Step 4: Test Before Committing
Don't choose a signature scent without testing it.
Method:
- Select 3 candidates
- Use each one for 1 week in your business
- Gather feedback from customers and staff
- Choose the one that generates the most positive comments
Common mistake: Choosing your personal favourite scent. Choose the one that works for your customer.
Step 5: Implement Consistently
If you choose a signature scent:
- Use it ALL THE TIME
- At EVERY touchpoint
- At least 2 years to create an association
Changing it every month = zero impact on scent memory
Step 6: Measure Results
Metrics to track:
Retail:
- Average dwell time
- Average spend
- Total sales
Hotels:
- Online "ambience" ratings
- Repeat customer rate
- Mentions of "smell" in reviews
Restaurants:
- "Cleanliness" ratings
- Odour complaints
- Average length of stay
Compare 3 months before and 3 months after.
Common Mistakes in Scent Marketing
Error 1: Scent That's Too Strong
More isn't better. An overpowering scent puts customers off.
Rule: If the customer consciously notices it, it's too strong.
Solution: It should be subtle, almost subliminal.
Error 2: The Wrong Scent for the Sector
Sweet jasmine in a gym = a mistake. Medicinal eucalyptus in a fashion shop = a mistake.
Solution: Study which scents your successful competitors use.
Error 3: Changing the Scent Constantly
If you change it every month, you’ll never create a scent–brand association.
Solution: At least 2 years with the same signature scent.
Error 4: Failing to Consider Sensitivities
Some customers are allergic or hypersensitive.
Solution: Offer a fragrance-free option where possible (e.g. hotel rooms).
Error 5: Ignoring Ventilation
Scent without adequate ventilation = saturation.
Solution: Scenting + ventilation = the perfect balance.
Frequently Asked Questions
Does scent marketing really work, or is it a placebo?
It works. Dozens of peer-reviewed scientific studies demonstrate a measurable impact on sales, time spent in-store and perceived quality.
It isn’t magic; it’s neuroscience.
How much does it cost to implement scent marketing?
From €25/month for a small business to thousands of euros per month for chains.

Not mandatory. You can start yourself with:
- Quality professional air fresheners

Counterproductive for professional scent marketing.
