Description

  The present invention relates to a server, a method, and a program for providing information related to merchandise sales via a communication network. In particular, the present invention relates to a server, a method, and a program for providing information related to product sales based on product selection similarity via a communication network.

  Conventionally, various techniques have been proposed as a method for providing information related to product sales to a terminal connected via a communication network such as a mobile phone or a PC.

  For example, in Patent Document 1, when a customer views a page of an individual product, information related to an order previously made by the customer is displayed. This eliminates the need to contact customer service to know if the ordered item has been shipped.

  Or in another Example, the information of the related goods which the other customer who ordered the said goods ordered more actively is displayed, and the purchase of a related goods is also performed.

JP-T-2004-535015

  However, all such information provisions can be displayed only after the user accesses the site and further performs a selective browsing operation on a page of an individual product. Therefore, the related product information is not displayed before the customer browses such a page.

  As a result, many input operations such as those described above are carried out especially on mobile phone product sales sites that have handy input device functions compared to PCs that can use input devices with rich functions such as keyboards and mice. Enforcement may reduce the opportunity to provide information about related products.

  Therefore, an object of the present invention is to provide information related to product sales that is more actively adapted to the user before browsing individual product pages.

  Instead of focusing on “products” as in the past, the present inventors focused on “people” who have selected products, and information on users who have accessed the product sales site and have high similarity in product selection. Based on this, the present inventors have found a method that can provide merchandise sales information accurately and have completed the present invention. More specifically, the following is provided.
