Research Impact

Alternative Metrics

Alternative metrics are based on data generated by the use of and interaction with information online, such as number of downloads and pageviews from a publisher, repository or online reference managers, or the amount of discussion generated in online venues such as twitter or blogs.

Alternative metrics can be used to compliment traditional metrics, to measure impacts in fields where citation metrics aren't as applicable, or to show the impact of research on a broader audience.
