The Altmetric Badge looks like a donut. It can be embedded in individual profiles, publisher websites, and institutional repositories free of charge.

You can find the donut on a research output page in the CUHK Research Portal and some publisher websites as Cambridge Core, Springer Nature, and PLOS. PLOS has a page dedicated to curating all outputs with altmetrics from Altmetric

Below is an example of the Altmetric Badge in the CUHK Research Portal. By clicking the donut, you will access the Altmetric details page of the research output.
