This meta-analysis aims to examine and compare the pleasant ambient scent effects on consumers’ affective, cognitive and behavioural responses in the retail and hospitality sectors.

55 articles, including 102 effect sizes, are collected from electronic databases and search engines. The effect of pleasant ambient scents on consumer responses is examined using meta-regression analysis.

The results show a positive effect of pleasant ambient scent on all responses in both sectors, while the effects on cognitive and behavioural responses are stronger in hospitality than retailing. Moreover, the scent effects in hospitality research vary with method aspects, including sampling frame, research design, setting and location.

The findings provide theoretical insights on the sensory tangibilization of experience and methodological insights on designing scent research.

The stronger effect of pleasant ambient scents on cognitive and behavioural responses in a hospitality environment signals that contextual differences should not be neglected. Moreover, hospitality researchers need to stay vigilant to the methodological influence on the findings about scent effects. These findings enrich the sensory marketing literature, in which contextual comparison is scarce.
