The purpose of this study is to test the persuasive effects of visual metaphors in advertising. Advertisements containing visual metaphors deliver persuasive arguments in visual modality and metaphorical style of rhetoric, both of which may increase the persuasiveness of messages. The study has three message conditions that are advertisements containing (a) non‐metaphorical (literal) visual image with verbal argument; (b) metaphorical visual image with verbal argument; and (c) metaphorical image without accompanying verbal argument. Cognitive elaboration, source credibility, ad attitude, brand attitude, product belief, and purchase intention are considered as outcomes. The study results suggest that visual metaphors may be more persuasive due to both visual argumentation and metaphorical rhetoric. The theoretical explanations and managerial implications of the findings of this study are further discussed.
