What is an Altmetric score?

Altmetric calculates a score based on the online attention a publication receives. Each colored thread in the circle represents a different type of online attention and the number in the center is the Altmetric score. The score is calculated based on two main sources of online attention: social media and mainstream news media. Older publications will typically score higher because they have had more time to get noticed.
