We analysed more than six billion user comments from the social media website Reddit dating back to 2006, as well as 11.8 billion Twitter posts from as far back as 2011. In total, our research used a massive 5.6Tb trove of data from more than a decade of global activity.
In fact, between 60—70% of all attention on key social media platforms is focused towards just ten popular domains.
Beyond social media platforms, we also studied linkage patterns across the web, looking at almost 20 billion links over three years. These results reinforced the “rich are getting richer” online.
The authority, influence and visibility of the top 1,000 global websites (as measured by network centrality or PageRank) is growing every month, at the expense of all other sites.
