The Impact of Product-Model Ratio and Brand-Consumer Relationship on Advertising Effectiveness Abstract In advertising, visuals play an important role in drawing the attention of consumers to promoted brands or products. Recent research suggests that the spatial arrangements of visuals are important. Conceptual metaphors are heavily used to create appropriate visuals in advertising. Elaborating on the conceptual metaphor theory, this research study examines how the product-model ratio (in terms of size) influences advertising effectiveness. The brand-consumer relationship is proposed as a moderator. Three experiments are performed which differ in brands and products. Study 1 uses real brands, while Study 2 and Study 3 use fictitious brands. Study 1 employs a 2 (product-model ratio: large vs. small) x 2 (brand-consumer relationship: leader vs. friendship) full-factorial design. Study 2 takes product type (hedonic vs. utilitarian) into consideration to rule out possible effects on the interaction between product-model ratio and brand-consumer relationship. Study 3 replicates the results of Study 1 by using an Asian model and a brand name in Chinese. Purchase intention and attitude toward the ad serve as dependent measures. The results indicate that ads with a greater product-model ratio (i.e., the product image is well larger than the image of the model) work better when consumers consider the brand as a leader. On the contrary, ads with a small product-model ratio are advantageous when the brand is viewed as the consumer’s friend. This study finds that processing fluency is the underlying mechanism that explains this phenomenon. 【 Keywords 】 product-model size ratio, brand-customer relationship, conceptual metaphor, advertising effectiveness Chun-Tuan Chang , Department of Business Management, National Sun Yat-sen University 張純端 / 國立中山大學企業管理學系 Hsin-Yi Wang , Department of Business Management, National Sun Yat-sen University 王欣怡 / 國立中山大學企業管理學系 Received 2016/9, Final revision received 2018/8 NTU Management Review Vol. 30 No. 1 Apr. 2020, 131-162 領域主編：謝依靜
