Abstract: An advertisement extraction device according to the present application has a calculating unit, a tallying unit, and an extracting unit. The calculating unit calculates a hypothetical advertisement effect for each user attribute of a user, based on a delivery history regarding advertisement content delivery to a terminal device used by the user. The tallying unit tallies up an advertisement effect for each piece of advertisement content in which a user attribute as a delivery object has been decided, through the use of the hypothetical advertisement effect corresponding to the user attribute as the delivery object in the advertisement content among the hypothetical advertisement effects for each of the user attributes calculated by the calculating unit. The extracting unit extracts the advertisement content as a delivery candidate, based on the advertisement effect tallied up by the tallying unit.

Abstract: An advertisement information providing device includes an advertisement content storage unit that stores advertisement content of a plurality of types. The advertisement information providing device includes an expected earning calculation unit that calculates expected earnings per unit impression number for each type of the advertisement content or for a combination of a plurality of types of the advertisement content. The advertisement information providing device includes an advertisement content type determination unit that determines which type of the advertisement content or combination of types of the advertisement content is to be delivered based on the expected earnings. The advertisement information providing device includes an advertisement content delivery unit that acquires the type of the advertisement content or combination of types of the advertisement content and delivers the advertisement content to an advertisement space.

Abstract: An advertisement information providing device includes an advertisement content storing unit which stores impression-guaranteed type advertisement content and time basis billing type advertisement content, an advertisement content determining unit which, when receiving a page browsing request from a terminal device of a user, determines advertisement content to be delivered from the impression-guaranteed type advertisement content and the time basis billing type advertisement content stored in the advertisement content storing unit, and an advertisement content delivering unit which delivers the advertisement content determined by the advertisement content determining unit to an ad space included in a page for which the page browsing request is received from the terminal device of the user.

Abstract: An advertisement delivery apparatus includes a related information acquiring unit, a similarity determining unit, terminal estimating unit, and an advertisement delivery unit. The related information acquiring unit receives a plurality of pieces of related information from each of communication terminals. The related information is information about each of the communication terminals and is unable to identify each of the communication terminals. The similarity determining unit determines similarity of the pieces of the related information received from the communication terminals. The terminal estimating unit estimates that the communication terminals are a same communication terminal based on the similarity. The advertisement delivery unit, when the communication terminals are determined as the same terminal, delivers an advertisement corresponding to a behavior of a same user to the communication terminals each serving as a transmission source of the related information.
