Tweaking its strategy to account for the expected surge in mobile bookings, the company is broadening the number of hotels bookable through its Instant Booking feature, while at the same time acquiring destination-listing websites. Late last month, TripAdvisor said its Instant Booking feature, which went live in June, would add hotel inventory from GDS operator Travelport, giving users booking access to Travelport’s listings for 580,000 hotels worldwide, including 480,000 non-branded properties. Additionally, TripAdvisor last month agreed to pay $200 million to acquire Viator, an online service that offers customers access to more than 20,000 tours and attractions in 1,500 destinations worldwide. The announcements reflect a bifurcated strategy of sorts for TripAdvisor: Derive more revenue per visitor from the contingent of people visiting TripAdvisor specifically to book hotel rooms and, at the same time, own more listing services that cater to the TripAdvisor visitors who are looking to book travel products other than hotels.
