Impact of Online Consumer Reviews on Sales Dynamics
Summary
Online consumer reviews have emerged as a pivotal driver of sales dynamics across digital marketplaces. As consumers increasingly turn to peer-generated feedback to inform purchasing decisions, the volume, valence and content richness of reviews shape demand trajectories for a diverse range of products. Positive reviews can accelerate sales growth, while negative or ambiguous feedback may dampen demand or prompt corrective actions from firms. Recent work highlights how review characteristics interact with product category, popularity and consumer demographics to modulate buying behaviour. Furthermore, the interplay between conventional reviews and supplementary eWOM channels, such as customer Q&As, introduces feedback loops that both inform and amplify purchase intentions. Firms deploy incentive schemes, content moderation and platform design interventions to manage review supply and quality, balancing the need for authenticity with marketing objectives. Advances in econometric modelling and big data analytics now enable real-time monitoring of review-driven sales fluctuations, providing actionable insights for retailers, platform designers and policy-makers worldwide.
