Accruing citations to your journal articles is a slow process. Altmetrics (e.g., number of article views or downloads, number of shares or mentions in social media) are faster measures of how people--both other researchers and the general public--are interested in your work.
ImpactStory brings together a diverse assortment of altmetrics for all of your research outputs, including journal articles, datasets, computer code, and slides. Twitter users can sign up for a free ImpactStory account.
The free Altmetric Bookmarklet can be easily installed in Chrome, Firefox, and Safari browsers. Navigate to a journal article webpage and click "Altmetric it!".
PLoS Reports: Article-Level Metrics (ALM) is a free tool that provides a variety of altmetrics for articles published in PLoS journals. Other journal publishers, such as Wiley, Elsevier, and Springer, also provide altmetrics for some of their articles and/or journals.
