This device for providing information (30) is provided with: an identification unit (33a) which refers to a browsing history database (22) which stores a history of browsing transaction object pages by a user, performs a comparison with a first transaction object as laid out in a first transaction object page displayed upon a user terminal (10), and identifies a second transaction object as laid out in a second transaction object page; a comparison unit (33b) which extracts first transaction object information corresponding to the first transaction object and second transaction object information corresponding to the second transaction object from a page information database (21) which stores transaction object information corresponding to the transaction objects in order to compare the first and second transaction object information units; and a page transmission unit (34) which presents comparison information indicating the comparison results to the user. Here, the second transaction object page is a Web page displayed upon the user terminal (10) before the first transaction object page.
