Seeking to explore the nature of European far-right online ecosystems, this research report examines the outlinking activity of identified pro-far-right users among the followers of the official Twitter accounts of two prominent far-right European political parties, Germany’s Alternative für Deutschland (AfD) and France’s Rassemblement National (RN). Employing a three-layered analysis, the report explores not just the top-level domains outlinked to by its sample of AfD and RN Twitter followers but combines this with analysis of the technical specifications of the content types outlinked to and treatment of the socio-political nature of the content arrived at by clicking on the most tweeted URLs. This results in the provision of a more thorough and cohesive view of this online ecosystem than contained in other similar studies.
