    The colours of the Altmetric donut each represent a different source of attention

    The colors of the Altmetric donut each represent a different source of attention.

    The amount of each color in the donut will change depending on which sources a research output has received attention from.

  • The Attention Score

    The score is an automatically calculated and weighted count of all of the attention a research output has received and is based on 3 main factors:

    Volume Sources Authors
    The score for an article rises as more people mention it. We only count 1 mention from each person per source, so if you tweet about the same paper more than once, Altmetric will ignore everything but the first. Each category of mention contributes a different base amount to the final score. For example, a newspaper article contributes more than a blog post which contributes more than a tweet. We look at how often the author of each mention talks about scholarly articles, at whether or not there's any bias towards a particular journal or publisher and at who the audience is. For example, a doctor sharing a link with other doctors counts for far more than a journal account pushing the same link out automatically.

    Combined, the attention score represents a weighted approximation of all the attention we’ve picked up for a research output (not a raw total of the number of mentions). You can find more detail about how it’s calculated, including the standard weightings on the Altmetric website.

  • How is the Altmetric Attention Score calculated?

    The Altmetric Attention Score for a research output provides an indicator of the amount of attention that it has received. The score is a weighted count and is derived from an automated algorithm, reflective of the default weightings being:
