Online shopping has become popular due to the growing market of e-commerce, accessibility to the internet technology, and the availability of a wide range of mobile shopping applications. Like traditional shopping, online consumers’ understanding, and interpretation of product information may be influenced by certain factors. Such factors may affect the buying decisions and in return impact the online sales performance of ecommerce platforms. A fair number of studies were conducted to examine the overall factors that may have an impact on the sales performance of e-commerce businesses. One of the leading factors found is “online consumer reviews”. Existing studies were mainly conducted on e-commerce websites that are mainly based in the United States, China, and India. Thus, there is a lack of studies examining the influence of consumer reviews on ecommerce sales within the Arabian Gulf Region despite it being a highly attractive ecommerce market with an increase in profits from $5 billion in 2015 to $20 billion in 2020. This study aims to fill this gap by analyzing the influence of online consumer reviews on the online sales performance of Amazon.ae by developing a research model and testing its hypothesis. Additionally, this study examines the moderating effect of product category on the influence of online consumer reviews on online sales performance. Amazon.ae was selected considering it is one of the leading e-commerce platforms in the Gulf Region. A total of 5,066 product records were collected across 8 product categories. The findings of this study revealed that online review ratings do not influence the online sales performance of Amazon.ae. On the other hand, online review volume significantly influences online sales performance. The findings also revealed that product category affects the overall relationship between online consumer reviews and sales performance. These findings contribute to the literature by examining how online consumer reviews affect online sales performance in a Gulf-region-owned e-commerce website. In addition, the findings can help decision-makers within the field of e-commerce to better understand how online reviews are impacting their sales, and which component of the online review has the greatest influence on their sales.
