Expedia Group Inc, TripAdvisor Inc and eDreams Odigeo SA asked the European Union to investigate how Google shows vacation rentals, claiming it unfairly gets a prominent placing above other search results.
In a letter to EU Competition Commissioner Margrethe Vestager published online, more than 30 travel firms allege that Google is "favouring its own service in general search results pages” by displaying ads "in a visually-rich OneBox” showing pictures, a map preview, ratings and prices. The display "secures Google’s service more user attention and clicks than any competing service may acquire”.
