TripAdvisor is the second-most visited website (after Google) by foreign tourists arriving in Israel... In our campaigning, we have asked [TripAdvisor CEO Stephen Kaufer] to stop listing or promoting properties, activities and attractions located in illegal Israeli settlements in the Occupied Palestinian Territories. TripAdvisor responded by claiming that "[t]he listing of a property or business on TripAdvisor does not represent our endorsement of that establishment". 

Yet the company does make a profit from listings including those in illegal Israeli settlements... we found that TripAdvisor has prominently featured, and acted as a booking agent for the City of David, a popular tourist attraction located in Silwan, a Palestinian neighbourhood in occupied East Jerusalem. The site is managed by an organisation called the Elad Foundation, which is backed by the Israeli government and works to help Israeli settlers move into the area... By actively encouraging users to visit the City of David and take guided tours of the site, TripAdvisor has boosted Elad's business and profited from every booking made through its site.
