Abstract: The interaction of shoppers and the posts they make on the web generates an enormous amount of information. Buying decisions through social commerce are influenced by the shoppers sharing of their experiences and expertise in buying online as well as learning from other’s experiences. It is necessary to understand the nature of virtual societies, so that, companies operating through social commerce can determine the market and the type of shoppers, whether present or prospective in the market. With the rapid and successive developments in information technology, investors and consumers who represent the supply and demand sides are moving towards social commerce and this is what highlights the importance of social commerce in recent times. In social commerce, consumers base their purchasing decisions on gathering information across the web. Social commerce components include reviews and ratings, forums and virtual communities and recommendations. These components are a major source of information and important customer interaction tools for social commerce. This study aims to examine the relationship between the components of social commerce and the stages of online purchase decision-making. The research model contributes to a better understanding of the effect of the social commerce components on the stages of the purchasing decision process. The results showed the weak effect of the social commerce components on the need identification stage in the purchasing decision process. As for the rest of the decision-making stages, the results showed that the social commerce components have a positive effect on the information search stage, the alternatives evaluation stage, the purchase decision stage and the post-purchase stage in the purchasing decision process. Based on the results of the paper, reviews and ratings are the most influential component of social commerce in the purchasing decision process, followed by forums and virtual communities. Recommendations are the least influential component of social commerce in the purchasing decision process.
