Executives rarely ask whether a logo works. They ask whether it pays. When the conversation turns to scent — a diffuser in the lobby, a signature candle on the desk of every new hire, a scent logo carried through every touchpoint — the same question gets sharper. Is this brand equity, or is this budget theater?
The answer sits in the data. Over the last two decades, researchers, retailers, and casinos have quietly built a receipt for what scent does to a buyer’s brain and a seller’s P&L. The numbers are not flattering to brands that ignore them.
This is what the evidence says — and how to measure it inside your own four walls.
The Numbers Executives Actually Need
Scent is the only sense that bypasses the thalamus and routes directly to the limbic system — the brain’s emotion and memory core, built around the amygdala and the hippocampus (Harvard, Venkatesh Murthy; British Psychological Society). Translation for the budget meeting: smell is processed next to the neurons that store feeling, and people buy with feeling.
The downstream commercial effects are measurable:
• 75% of daily emotions are triggered by smell (Mood Media)
• Consumers are 100x more likely to remember a smell than something they see, hear, or touch (Mood Media / Sense of Smell Institute)
• 65% recall accuracy for scent after one year, versus 50% visual recall after three months (Sense of Smell Institute)
• 84% of consumers are more likely to recall a brand that uses a signature scent (industry research, 2025)
• A pleasant ambient scent improves mood by roughly 40% (International Flavors and Fragrances)
None of this is soft. Every line item above has a dollar figure sitting underneath it. The rest of this post is the conversion.
Dwell Time: The Minutes That Convert
The easiest scent metric to measure is time. How long does a customer stay once they enter?
Scented environments lift dwell time by at least 15 minutes across multiple retail and hospitality studies (Mood Media). In a casino study, scented areas produced a 40% increase in dwell time and a 45% revenue lift. A Samsung showroom experiment found that shoppers underestimated the time they had spent browsing by 26% and moved through 3x more product categories in the scented environment (Mood Media).
Every additional minute a qualified buyer spends in your environment is a minute of exposure to your product, your story, and your staff. If your average basket size is $80 and scent adds a measurable lift in time-on-floor, the math is not a mystery — it is a multiplier you can track in your POS data.
Purchase Intent and Willingness to Pay
Dwell time is upstream. Conversion is downstream. Scent moves both.
In a frequently-cited Nike study, a pleasantly scented retail environment produced an 84% increase in purchase intent, and customers reported they would pay 10% to 20% more for the same product in a scented store versus an unscented one (Mood Media). That is not a brand halo — that is pricing power.
For private-label and corporate-gifting programs, the equivalent metric is perceived value. A candle that arrives in a custom vessel with a fragrance a recipient has never smelled anywhere else does not compete with the $24 mass-market jar on Amazon. It sits in its own category, and the recipient prices it accordingly.
Brand Recall: The KPI That Lives the Longest
Recall is the KPI marketers quietly obsess over. Impressions are cheap. Memories are not.
Rockefeller University’s short-term recall data puts smell at 35%, versus 5% for sight, 2% for hearing, and 1% for touch. Over longer horizons, the Sense of Smell Institute found that people recall scents with 65% accuracy after a year, while visual recall drops to 50% after only three months. The “Proust Effect,” documented in Frontiers in Neurology and across peer-reviewed literature, describes odor-evoked memories as more vivid and more emotional than memories cued by any other sense.
Put differently: a brand with a distinct scent is still in a customer’s head a year after the interaction. A brand with only a logo is usually not.
How to Measure Scent ROI in Your Own Brand
The reason scent is under-measured is not that it is unmeasurable. It is that most brands never set a baseline.
Four metrics are practical to track:
• Dwell time — door counters, Wi-Fi analytics, or staff observation pre and post scent rollout
• Conversion rate and basket size — existing POS data, split by pre and post window
• Brand recall — a two-question post-visit or post-event survey asking recipients to describe the brand in three words and to recall any sensory detail
• Repeat visit / repurchase rate — loyalty data segmented by customers who experienced the scented environment versus those who did not
The global scent marketing category is on track to move from $3.6B to $6.4B by 2033, a 6.6% CAGR (industry projections). That growth is being funded by brands that have started measuring.
Where Scent Generates the Highest Return
Not every channel produces equal lift. The highest-ROI use cases we see inside the Blanco Building fall into three categories.
Retail and hospitality environments. Hand-poured candles and room sprays are part of the Shinola retail and Shinola Hotel experience, sold as S.01 and S.02 (Shinola.com). The scent is not a gift-shop accessory — it is part of why the brand feels like a brand.
Co-branded takeaways at scale. DetroitWick’s Trip Wipes line has sold more than 14 million units, with co-branded Trip Wipes deployed by Delta Air Lines as part of its Global Cleanliness initiative (Crain’s Detroit Business). When a scent ships on every seatback, recall compounds.
Signature corporate gifting. Brands like StockX, TRUFF, Wachler Diamonds, and Detroit Vs Everybody have used corporate gifting programs anchored by a custom candle to stay in a client’s home office long after a pitch deck has been closed. Wachler Diamonds’ limited-edition Tennis Club candle lives in premium smoked glass that nobody throws away.
The through-line: the brands with the clearest ROI story are the brands that treat scent as infrastructure, not as a giveaway.
Frequently Asked Questions
Does scent marketing actually work?
Yes. In published studies, scent has produced an 84% lift in purchase intent (Nike), a 45% revenue lift in casino environments, a 40% mood lift (International Flavors and Fragrances), and a 100x recall advantage over sight, sound, or touch (Mood Media / Sense of Smell Institute).
What is the ROI of scent marketing?
ROI depends on channel and baseline, but the inputs are well-documented: dwell time lifts of 15+ minutes, willingness-to-pay increases of 10% to 20%, and recall accuracy that outlasts visual advertising by a wide margin. Brands with POS data and a pre/post measurement window can usually isolate the revenue lift within one quarter.
How do you measure the business impact of olfactory branding?
Track four numbers: dwell time, conversion and basket size, brand recall via a short survey, and repeat-visit rate. Set a baseline for at least two weeks before any scent rollout, then measure the same windows again 30, 60, and 90 days after.
Why is scent more memorable than sight or sound?
The olfactory nerve is the only sensory pathway that bypasses the thalamus and routes directly to the limbic system — the amygdala and hippocampus — which handle emotion and memory (Harvard, Venkatesh Murthy; British Psychological Society). That is why a smell can snap a customer back to a location they visited years ago.
How much does a scent branding program cost?
Pricing is scoped to the engagement. Contact DetroitWick for a quote on a scent logo, private label run, or diffusion program.
Do we own the scent formula?
Yes. When DetroitWick develops a scent logo for a brand, the brand owns the formula in perpetuity. It becomes intellectual property and can be translated into candles, room sprays, diffusion, packaging inserts, and corporate gifts.
Can scent work for B2B and professional services, not just retail?
Yes. The strongest B2B use case is a signature gift that stays in a client’s home or office. Scented packaging inserts, scented business cards, and private-label candles are used by professional-services firms to keep their brand in rotation long after the meeting ends.
Where is this market headed?
The global scent marketing category is projected to grow from $3.6B to $6.4B by 2033, at a 6.6% CAGR (industry projections). 84% of consumers say they are more likely to recall a brand that uses a signature scent (industry research, 2025).
Build the Business Case, Then Build the Scent
Scent is one of the few brand investments with a century of neuroscience behind it and two decades of retail data in front of it. The brands that are winning the recall war are not waiting for the category to fully price itself. They are running the pre/post test now.
If you want a signature formula that can carry across retail, gifting, and events — and a partner that manufactures it in-house rather than outsourcing it — talk to DetroitWick.
