The so-called ‘alt-right’ is an amorphous but synchronized collection of far-right people and movements, an umbrella label for a number of loosely affiliated social movements around the world, although its centre of gravity is in the United States. Many factors have contributed to the alt-right’s rise to prominence, but one of the most visible is its online presence. Alt-right views have been promoted online by a small army of trolls and activists staging harassment campaigns, pushing hashtags and posting links to extremist content and conspiracy theories on social media. Since 2016, the alt-right and its allies have held an increasingly prominent place in American and European politics, rallying support behind a variety of causes and candidates. This study seeks to evaluate the alt-right’s online presence with robust metrics and an analysis of content shared by adherents. The alt-right has many components online; this report will primarily examine its presence on Twitter, in part because the movement is particularly active on that platform, and in part because Twitter’s data access policies allow for more robust evaluation than is possible on other platforms.
Erratum: Due to a collection error discovered after publication, some tweets in this dataset were truncated. This mainly affected the precise counts of top hashtags and may also have had a minor impact on the order in which hashtags were ranked. We do not believe the impact is material to the study’s overall findings.
