Definition

Social network analysis (SNA) is the study of social relationships in terms of network theory, focusing on the structure of social interactions among individuals, groups, or organizations. This analysis helps to visualize and quantify the patterns and relationships that emerge in social media and user-generated content, revealing insights into how information flows and how communities are formed. By leveraging data from social networks, SNA provides valuable metrics that can influence marketing strategies, community engagement, and understanding of social dynamics.
