The new approach to evaluate articles is to evaluate each article on its own merits, regardless of the journal where the article is published. This is done by using article level metrics, altmetrics. Altmetrics focuses on social media e.g. discussions in blogs, tweets in Twitter, amount of downloads of an article, citations and mentions in Mendeley. In comparison to bibliometrics altmetrics is very fast. It takes years for an article to get citations. In opposite an article can get tweets in one day.
