The importance of functional and emotional content in online consumer reviews for product sales: evidence from mobile gaming market

rior research on online consumer reviews (OCRs) has focused more on the volume and valence of all OCRs as a whole and less on their individual contents. This paper investigates the importance of multidimensional OCR contents, in terms of functional and emotional dimensions, in online marketing. Utilizing a rich dataset of four million online postings and weekly sales for 342 mobile games, this study identifies subcategories of functional OCRs – product quality, product innovativeness, price acceptability, and product ease-of-use – and emotional OCRs – anger, fear, shame, love, contentment, and happiness. The results show that the volume of product quality and ease-of-use OCRs drives more sales than the valence, while the valence of product innovativeness and price OCRs outperforms the volume. Furthermore, both negative and positive emotion-related OCRs moderate the relationship between functional OCRs and product sales. This study offers guidance to firms in managing specific OCR content for superior marketing outcomes
