Answer
Altmetrics are “alternative metrics” to measure the influence and reach of scholarly output on the Web through peer-review counts, influential news sites, blog posts, citation manager bookmarks such as Mendeley, Wikipedia citations, and social media mentions on sites such as Twitter and Facebook. The library has a research guide on Bibliometrics, which contains a section on Altmetrics to help you learn more about what they are and how to find altmetrics on specific journals.
