It is nearly three years since TripAdvisor started its shift away from being solely a review site (with lots of display and link advertising). With the launch of on-site booking capability, TripAdvisor's position has gradually morphed into that of an online travel agency. Tnooz has conducted three cuts of Hitwise data, covering traffic in the US, UK and Australia. The data is for October 2015 and does not include year-on-year comparisons, given that this is the first time that both desktop and mobile web traffic have been combined. The key finding - TripAdvisor dominates in terms of monthly visits across the US, the UK and Australia alike. Find out more.
