Altmetrics is a way to measure the impact of research beyond traditional citations. It looks at various online activities, such as mentions on social media, blog posts, and news articles, to gauge how often and in what ways research is being discussed and shared. These metrics provide a broader view of a research work's influence, especially in real-time. By tracking engagement across platforms like Twitter and Facebook, altmetrics can highlight the immediate relevance of research, helping researchers and institutions understand their work's reach and impact in the digital age.
