Alternative metrics or altmetrics are a family of indicators that measure the impact of research quantifying its presence
on the social web. The name comes from the concept "alternative metrics" or complement to more traditional impact
factor and bibliographic citations. And also from the concept “article-level metrics”.
Example taken from the UPF Scientific output:
Altmetric.com is a system that tracks the attention that research outputs such as scholarly articles and datasets receive online and presents it with their donuts with the score and colors for each group of indicators.
