: Because our research did not involve data collection from human users or any interaction with human users, it was exempt from the ethical review under the guidelines of the Ethics Committee of the Faculty of Economics, Business and Informatics of the University of Zurich. Further, since our search agents that did not perform actions such as clicking on specific items, we believe that our study did not interfere with the search algorithms in any potentially harmful way or affect the engagement statistics for individual results or put a heavy load on the search engines that could potentially affect their functionality.
