Auditing Google's Search Algorithm: Measuring News Diversity Across Brazil, the UK, and the US
Raphael Hernandes, Giulio Corsi·October 31, 2024
Summary
Google's search algorithm significantly influences news diversity in Brazil, the UK, and the US, favoring a limited number of news outlets and leading to concentration trends. The algorithm's biases, influenced by factors such as popularity, political bias, and recency, can reinforce existing media inequalities. Google, with over 90% global market share, acts as a key gatekeeper in news distribution, affecting readers' exposure to diverse content and viewpoints. The study highlights the importance of analyzing multiple search queries to uncover these patterns, as focusing solely on individual results may be misleading. The research provides comprehensive, longitudinal insights into how algorithms shape public access to diverse news sources, emphasizing the need for transparency and policy interventions to promote equitable news distribution.
