The term "altmetrics" (alternative metrics) is used to describe approaches to measure the impact of scholarship by using new social media tools such as bookmarks, links, blog postings, inclusion in citation management tools, mentions and tweets to measure the importance of scholarly output.
Proponents of altmetrics believe that using altmetrics will help measure the impact of an article in a more comperhensive and objective way than was done with more traditional scholarly impact measures such as journal impact factor. However, there are limits to this approach and caution should be used to not rely on any one particular measure in evaluting the importance of scholarship.
