trivago股价下跌（讲解版）| E0915
Hotel search firm Trivago has warned investors of weaker-than-expected revenue growth in 2017, due to lower spending from hotels and other travel companies. The company, which is headquartered in Germany, makes money by charging hotels and other travel firms for advertising linked to bookings made by Trivago users. It has been spending heavily to establish itself as a go-to travel search site, akin to a hotel-focused Google, that allows users to compare prices across different platforms.
