TripAdvisor was an early adopter of the Facebook Platform, launching the Cities I've Visited app in 2007. After nearly five years, Cities I've Visited continues to be one of the most used apps on Facebook. In January, TripAdvisor relaunched Cities I’ve Visited with Open Graph to allow users to share the cities they've visited and their favorite places on timeline.
Cities I've Visited maps the frequent interactions people take – pinning a city and rating a place – to Open Graph actions to maximize the number of stories people publish. For new and existing users, Cities I've Visited encourages pinning cities and rating places to maximize sharing and generate stories.
Cities I've Visited uses custom properties - such as location - to create interesting timeline aggregations like "Total Distance Traveled" and "Percent of World Visited."
