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. This helps researchers understand the broader reach and influence of their work. Unlike traditional metrics, which focus mainly on journal citations, Altmetrics provides a more immediate and diverse picture of a research output's impact. It can highlight the relevance of research in real-time and across different platforms, making it a valuable tool for researchers and institutions.
