Abstract: Snapchat geofilter advertisements use augmented reality (AR) technology to place consumers in photographs embellished with branded content. This study examined the joint influence of self-brand congruity, self-referencing and perceived humor in these self-endorsed geofilter brand advertisements on consumers’ brand-related preferences. Results revealed that self-brand congruity, self-referencing and perceived humor exerted significant main effects on consumers’ post-use brand attitude and purchase intention. Self-brand congruity also significantly interacted with self-referencing and perceived humor to affect brand attitude and purchase intention, while self-referencing significantly interacted with perceived humor to affect purchase intention, but not brand attitude. Theoretical and managerial implications of the research are discussed.
