Wall Street Journal (I do not have a subscription and this was not paywalled when I looked at it, but your mileage may vary): Travel Sites Fault Google for Revenue Slowdowns. “TripAdvisor Inc. …and Expedia…Group Inc. are struggling to navigate shifts in how Google delivers information to consumers who use its search engine to plan travel. Shares of both travel-focused companies fell sharply Thursday after executives at both companies cited how Google handles travel-related searches. TripAdvisor’s stock fell 20%, while shares of Expedia dropped 25%.”
