Altmetrics are tools to measure the attention a scientific publication receives on the net. The company Altmetric, which offers the software, is part of the Digital Science Group and is an example of possible altmetrics. With Altmetric, it offers a tool that visually shows how much attention a scientific paper receives in various online media. The Altmetric score is regarded by many as a measure of social relevance and thus an indicator of impact. Yet, the Altmetric score does not provide a serious indication of the social relevance of a particular research.  Altmetrics are only able to measure the Impact of Science for research within a limited context, because they contribute to a scenario where researchers become more concerned with maximizing the number of likes, among other things. They do not automatically increase social relevance.
