Facebook announced Graph Search at today’s press conference which will allows users to search their open graph across people, photos, interests and places. Unlike prior search functionality, Facebook’s new service allows you to combine “phrases” like querying friends in San Francisco who like coffee shops. The new feature will certainly change the discovery process, allowing people to more proactively seek information instead of waiting for posts in their newsfeed. It also provides another opportunity for users to uncover brands in Graph Search, particularly for brick and mortar locations (think “shoe stores friends have liked near Chicago”). Stay tuned for some of the ad opportunities for the new offering.
