These metrics attempt to show the value of a particular article by times cited, as well as other factors. The number of downloads, times bookmarked, and social-media mentions may indicate a relationship between these numbers and the number of times an article is cited in the academic literature in the future. This might help new researchers gauge or predict their impact. They may also be useful in measuring community impact.
Some publishers (e.g. Elsevier), databases (e.g. ScienceDirect), and journals (e.g. PLOS ONE) provide Altmetrics data alongside with the article information.
