Trivago is a global online hotel metasearch platform that helps travelers compare accommodations and prices across multiple booking sites while connecting hotels and online travel agencies with potential customers. The company generates revenue primarily through referral commissions, charging advertisers—mainly online travel agencies, hotel chains, and independent hotels—on a per-click or per-acquisition basis when users click through to book hotels, supplemented by subscription services for hotels and direct booking operations. Trivago operates across the Americas, Europe, and other international markets, with traffic driven by content quality, pricing, ratings, marketing investments, and user experience, while its revenue per referral depends on advertiser bidding dynamics and booking conversion economics.
