Description

The present disclosure relates to programs, information processing apparatuses, and methods.

2. Description of the Related Art There is a technology for displaying an advertisement for a product of a service for purchasing products through electronic commerce (for example, an EC (Electronic Commerce) site) on an external service. When a user searches for a product or the like with some search query in an external service, a page is displayed as a search result corresponding to the search query, and an advertisement for the product corresponding to the search query is displayed. Such advertisements are often displayed as, for example, product listing advertisements (PLAs) that list products.

Also, conventionally, cookies have been used for user targeting. However, there are cases where it is not preferable to use cookies from the viewpoint of personal information protection, fraud prevention, and the like. As an alternative, there is a technique of generating segments by generating cohorts based on collected user information (Patent Document 1).

Special Table No. 2017-505499

However, in advertisements distributed to external services, it is not possible to grasp detailed information about products in the EC site that serves as the product publication source. For example, in an external service, logs such as information related to product searches within the EC site cannot be grasped. This is because external services and EC sites use different methods of acquiring logs such as search information. In addition, there are cases in which cookies cannot be obtained in web browsers. Therefore, even if an advertisement is posted on an external service, there is a problem that it is not possible to encourage users to visit the target EC site and to appropriately encourage the purchase of products.

Therefore, in the present disclosure, a technology is provided that can distribute to an external service an advertisement that encourages a user to visit an EC site.

A program according to the present disclosure is used in a system for displaying an advertisement of a product handled by a second service for purchasing products on a first service, and is a program for operating a computer including a processor, The program causes the processor to obtain a search query used by the user for searching in the first service, and a search model that outputs product information in the second service when the search query is input. determining, as a search result for the search query, at least one product handled by the second service as an advertisement target; and in the first service, advertising the determined product to the user. a step of displaying;

According to the present disclosure, it is possible to deliver an advertisement to an external service that encourages the user to visit the second service.
