What does the data include?
Altmetric tracks detailed metrics and mentions for discussions of research outputs (e.g. datasets, journal articles, monographs) on the Web. We capture all mentions where a research output with a compatible persistent identifier and adequate metadata has been linked to in any of the sources we track. The bulk of our data contains mentions from 2011 onward. For more details on our data collection practices, please visit our knowledge base.
What doesn’t the data include?
Our data does not include social media topics and hashtags unless they are associated with discrete research outputs. We also do not track downloads and pageviews, due to concerns over data reliability.
To apply for free Altmetric access, please tell us about your research. We’ll review your application (with an aim to respond within 10 business days) and let you know if Altmetric would be a good fit to answer your research questions.

- Ready to publish your Altmetric-related study? Read this guide on How to cite and describe Altmetric data in publications
- Researchers using Explorer for their data retrieval should review this Introduction to using Altmetric Explorer
- Explorer users can query up to 25,000 identifiers at once using Advanced Search in Altmetric Explorer
API and database snapshot users
- API users and database snapshot users should check out the Altmetric Details Page API documentation and Full Access API example to see which fields are available for retrieval and analysis
- Researchers have developed some nice packages for using the Altmetric Details Page API, including rAltmetric (R), PyAltmetric (Python), and altmetric (Ruby). Altmetric API keys are required to work with these packages. Note that these packages are not developed nor maintained by Altmetric; please contact the packages’ respective owners for more information or to report bugs.
