In the fast-paced world of marketing, where digital screens dominate and scents seem impossible to convey, what if I told you that a simple image could make your audience “smell” your product? It’s not magic, it’s science. As CMOs, we’re always hunting for that edge to boost evaluations and sales. Welcome to the power of olfactory imagery: the brain’s ability to conjure scents from visuals alone. This isn’t just theory; it’s backed by cutting-edge research that you can deploy today to elevate your campaigns.
Why does smell matter so profoundly? Unlike vision, hearing, taste, or touch, which all route through the thalamus before hitting higher brain centers, olfaction takes a direct expressway. Smell signals zip straight from the nose to the olfactory bulb, then dive into the amygdala and hippocampus: hubs for emotion and memory. This primal pathway explains why a whiff of freshly baked cookies can transport you back to grandma’s kitchen faster than any nostalgic photo. It’s evolution’s shortcut, making scents more visceral and memorable than other senses. In marketing, harnessing this means tapping into subconscious desires and explicit memories, forging deeper brand connections without ever spritzing a perfume.
Recent research amplifies this potential. A new study, “Seeing is Smelling: Pictures Improve Product Evaluations by Evoking Olfactory Imagery,” reveals how visuals on packaging or ads trigger imagined scents, enhancing product appeal and choice sharesā€”no actual aroma required. Across seven experiments and four supplemental studies, researchers found that scent-relevant images (think steaming coffee or blooming flowers) boosted evaluations by evoking positive olfactory mental pictures. The effect shines brightest for products where smell is key, like foods, perfumes, or cleaners, and among consumers with a high “need for smell.” But beware: for non-scent products or malodorous visuals (e.g., garbage in a deodorant ad), it backfires, tanking perceptions.
So, how do you put this into practice? Here’s your actionable playbook:
- Select Scent-Evocative Visuals Wisely: Opt for high-resolution images that imply aroma, like dew-kissed fruits for juices or sizzling grills for burgers. Test for relevanceā€”scent boosts only work when it’s intuitive.
- Target High-Need Audiences: Use data to segment “smell-sensitive” consumers (e.g., foodies or beauty enthusiasts) and amplify visuals in their feeds for up to 20% higher engagement, per the study’s insights.
- Avoid the Pitfalls: Skip negative scent cues; they evoke disgust and drop evaluations. A/B test images to ensure they spark joy, not nausea.
A powerful case study is Jacquemus’s 2024 “Bread and Butter” campaign. The luxury fashion brand flooded social media with surreal visuals of models lounging amid giant loaves and melting butter, evoking the warm, yeasty aroma of a Parisian bakery. Without a single scent strip, it drove viral buzz, spiking site traffic and sales by tying fashion to comforting, nostalgic smells. The result? A multisensory unexpected hook that made the brand feel indulgent and approachable.
A parallel can also be seen in tourism marketing. Think of a beach destination ad: a windswept shoreline, palms bending in the breeze, and crystal waves crashing. Even without a scratch-and-sniff postcard, these visuals cue the crisp scent of saltwater and sunscreen, pulling travelers into the promise of relaxation and escape. By leaning on olfactory imagery, tourism boards effectively make audiences smell the vacation before theyā€™ve even booked, proving that scent cues work just as powerfully for experiences as they do for products.
As CMOs, ignoring olfactory imagery means leaving money on the table. In a scent-starved digital era, visuals are your secret weapon to making brands “smell” irresistible. So, conduct a quick scent audit on your next campaign: Does it visually conjure irresistible aromas? If not, deploy these tactics, and your audience’s subconscious noses (and your bottom line) will thank you profoundly.
