Researchers ran an 18-day field experiment in a real home décor store, comparing no scent against a simple orange scent. Shoppers in the simple-scent condition spent 56.83 CHF on average, compared with 45.96 CHF in the no-scent control. Conditions were held consistent for pricing, advertising, and product availability.
The simple scent outperformed both no scent and the complex scent. The retailer kept advertising, pricing, and product availability consistent during the test.
Takeaway: Scent works best when it is clear, pleasant, and easy for guests to process — not when it is overly complex.
