While metrics like the h-index, citation counts, and the impact factor of journals demonstrate research influence in the academic realm, altmetrics, a relatively newer measure, can show the more immediate impact of work in a social realm. Alternative metrics are meant to complement traditional impact measures.
Altmetrics include social media activity, coverage in media outlets, and inclusion in policy documents or scholarly commentary, among other types of activity. Departments and disciplines currently incorporate altmetrics into tenure and promotion decisions variably; check with your department for guidance on best practices.
