The term altmetrics stands for alternative metrics. It's sort of like a crowd-sourced peer review process, finding new ways to monitor the use and impact of research in an online environment. Altmetrics considers how scholarship-based activities such as blog posts, tweets, downloads, shares, and views may provide important information about the significance of a research article or other research "product." More information can be found here.
Altmetric "collects the relevant discussions around each article from Twitter, Facebook, science blogs, mainstream news outlets, YouTube and many more sources - then makes it all available to you in one place. . . Each article is given a score that measures the quantity and quality of attention it has received." (Description from website). While there is a charge to subscribe to this service, Altmetric offers researchers a free bookmarklet that can be used in Firefox, Chrome and Safari to view metrics for articles found on the web.
