Abstract

When a user accesses an advertisement on an on-line advertising system from a user terminal on the Internet using a WWW browser, an advertisement including the toll-free telephone number of a store is sent to the user terminal. When the user calls this toll-free telephone number, a toll-free call control system connects that call from the user to the store and, at the same time, obtains information on that access to the toll-free telephone number as log information. This log information is posted to the service provider, and the service provider analyzes the hit rate from this log information and the WWW browser access log. From this result, the on-line service provider or the advertiser can determine the effectiveness of that advertisement.
