> The [Federal Court of Australia] ruled that from at least December 2016, Trivago misled consumers by representing its website would quickly and easily help users identify the cheapest rates available for a given hotel.

> In fact, Trivago used an algorithm which placed significant weight on which online hotel booking site paid Trivago the highest cost-per-click fee in determining its website rankings and often did not highlight the cheapest rates for consumers.
