The document discusses article-level metrics and altmetrics as tools to measure both academic and societal research impact beyond traditional citation-based analysis. It highlights how these metrics track the online attention and engagement, such as mentions in social media and news, that scholarly articles receive. Additionally, it describes various features of the Altmetric Explorer tool, which allows users to visualize and analyze the impact of scholarly work.

2. Every researcher is a communicator
Within academia
Presentations and seminars
Funding and ethics applications
Journal articles and posters
Term papers and essays
Meetings and conferences
Correspondence
Within society
Speaking at public events
Press
Social media
Blogs
How can we measure both
academic and societal research impact?

4. Each day, scholarly
articles receive ~12,000
new mentions across
social media, news, and
blogs.
That’s 1 mention
every 7 seconds!
Each week,
~20,000
unique articles are
shared.
Mentions range in
complexity, from
quick shares to
comprehensive reviews.
Article-level metrics are
worth paying attention to.

5. “Altmetrics” are…
o “alternative metrics”
o new ways of measuring different, non-traditional forms of impact.
o “alternative to only using citations”, not “alternative to citations”.
o complementary to traditional citation-based analysis.
Article-level metrics have come to refer to the altmetrics surrounding
a scholarly article.

6. What does Altmetric do?
§ We measure the online attention
surrounding journal articles and
