[System configuration]
The tracking system 10 according to the embodiment is a computer system for tracking general users (browsers) who browse advertising sites. FIG. 1 is a diagram showing an example of the configuration of a tracking system 10. As shown in FIG. In this embodiment, the tracking system 10 comprises a storage section 11, a transmission section 12, a reception section 13 and an execution section 14 as functional elements.

The storage unit 11 stores arbitrary information used in calculations and the like in the tracking system 10 and calculation results in the tracking system 10 and the like. The information stored by the storage unit 11 may be referred to by each functional element of the tracking system 10 as appropriate.

The transmitting unit 12 transmits a tracking identifier for identifying tracking of a general user to the general user side or the advertising site side when the general user makes a transition to the advertising site. The general user side includes, for example, terminal devices (PCs, smartphones, etc.) used by general users to browse web pages such as advertising sites, and programs executed by the devices. The advertising site side is a server device that constitutes the advertising site, a program that is executed by the device, and the like.

The transition (transition to an advertising site by a general user; hereinafter abbreviated as "transition" as appropriate) may be transition that does not go through a redirect server or an advertisement distributor's server (tracking system 10). That is, for example, it may be a direct transition from the advertisement page without going through the redirect server or the server of the advertisement distributor (tracking system 10). In that case, the URL (advertiser's link URL) indicated by the ad tag on the ad insertion page is the URL of the web page (for example, the advertiser's LP page) within the ad site.

The transmission unit 12 may detect the transition based on communication from the general user side or the advertising site side when the transition is performed. The communication may be a communication requesting a tracking identifier (to transmitter 12 or tracking system 10). Alternatively, the communication may be communication indicating that the general user has made a transition to the advertisement site, or may be communication including predetermined information.

The transmitting unit 12 may receive advertisement information related to the selected advertisement when a general user selects an advertisement on a web page (advertising page) for distributing advertisements and transition is performed. Advertising information is, for example, measurement parameters. When the transition is made, the transmission unit 12 provides any one of identification information for identifying the general user, IP address information for the general user, referrer information for the general user, or user agent (UserAgent) information for the general user. You may receive more than The identification information may be newly issued information (eg, by the advertiser system) when the transition was made. The transmission unit 12 associates the information (one or more of advertisement information, identification information, IP address information, referrer information, or user agent information) received when the transition is made with a tracking identifier (described later). (main storage unit 102, auxiliary storage unit 103, etc.).

The transmission unit 12 may newly issue a tracking identifier when the transition is made, and transmit the issued tracking identifier to the general user side or the advertising site side.

The transmission unit 12 may store the tracking identifier (in the main storage unit 102 or the auxiliary storage unit 103 described later) when the transition is performed.

The tracking identifier transmitted (to the general user side or the advertising site side) by the transmission unit 12 may be stored (in a memory or the like) on the general user side or the advertising site side.

The transmission unit 12 may further transmit identification information for identifying the general user to the general user side or the advertising site side (in addition to the tracking identifier) when the transition is performed. The tracking identifier and identification information transmitted (to the general user side or the advertising site side) by the transmitting unit 12 may be stored (in a memory or the like) in association with each other on the general user side or the advertising site side.

The receiving unit 13 receives the tracking identifier from the general user who transmitted the tracking identifier (the transmitting unit 12) or from the advertising site when a general user converts on the advertising site.

When a conversion (conversion by a general user on an advertising site; hereinafter abbreviated as “conversion” as appropriate) occurs, the receiving unit 13 receives the tracking identifier stored (in memory or the like) on the general user side or the advertising site side. It may be received (from the general user side or the advertising site side).

When a conversion occurs, the receiving unit 13 receives from the general user side or the advertising site side one or more of the contract information related to the conversion and the identification information that identifies the general user (in addition to the tracking identifier). may receive. The identification information received at the time the conversion occurred may not be used for tracking. For example, identifying information received when a conversion occurs may be used for reporting such conversions.

The execution unit 14 executes tracking based on the received tracking identifier. The executor 14 may perform tracking further based on a stored tracking identifier (in addition to the tracking identifier) (by the transmitter 12). In tracking, the executing unit 14 may determine whether the tracking identifier received (by the receiving unit 13) matches the tracking identifier stored (by the transmitting unit 12). In the present embodiment, existing technology is used to execute tracking based on the tracking identifier, and details thereof are omitted.

The tracking system 10 consists of one or more computers. When using a plurality of computers, logically one tracking system 10 is constructed by connecting these computers via a communication network such as the Internet or an intranet.

The tracking program 110 comprises a transmission module 111 , a reception module 112 and an execution module 113 . Functions realized by executing the transmitting module 111, the receiving module 112 and the executing module 113 are the same as the functions of the transmitting section 12, the receiving section 13 and the executing section 14 of the tracking system 10 described above, respectively.

[System operation]
The operation of the tracking system 10 and the tracking method according to the present embodiment will be described with reference to FIG. FIG. 4 is a diagram showing an example of a tracking flow of the tracking system 10. As shown in FIG. FIG. 4 shows the flow from when a general user selects an ad tag on an ad page until conversion occurs on the transition destination ad site.

In step S1 (click transition), a general user clicks (selects) an advertisement (advertisement tag) posted on an advertisement insertion page to directly transition to an advertisement site (advertiser LP page). The domain of the advertisement link (of the advertisement tag) posted on the advertisement page is the advertisement site and does not go through the redirect server of the advertisement distributor. The advertisement tag is a method of posting a fixed URL as text or the like. At least one or more of a determination parameter or a measurement parameter may be added to the URL parameter of the advertisement tag.

In step S2 (request), first, the advertiser system (a server program implemented in the advertiser LP page, or a client program that functions in a general user's browser, advertising site side or general user side), the advertiser LP page A parameter in the URL parameter given (fixedly) at the time of landing is taken out. If the determining parameter is retrieved, the advertiser system determines whether the transition is from a specific domain (eg, "valuecommerce.com") or site based on the retrieved determining parameter. If it is determined that the transition is not from a specific domain or site, the processes subsequent to step S2 and the processes of steps S3 and S4 described later are omitted. If it is determined that the transition is from a specific domain or site, the following information (some or all of the information may be absent) is communicated (collectively) to the tracking system 10.
・Measurement parameters (when extracted from URL parameters)
・Identification information that identifies general users (user ID. A unique character string given to each user by the advertiser, or a unique character string issued for each session, etc.)
・IP address information of general users ・Referr information of general users ・User agent information of general users

The measurement parameters may be held by the advertiser side (advertising site side) without communicating (sending) to the tracking system 10, or may be held by the advertiser side while communicating to the tracking system 10. You can leave it. The identification information may be generated by the advertiser system when the advertiser LP page is landed, or may be previously stored in the advertiser system. The communication of such information to tracking system 10 may be a request. More specifically, a request for a tracking identifier. The request is attached with the above information and communicated to the tracking system 10 . Any communication method is acceptable.

In step S3 (returning the tracking identifier), first, the tracking system 10 (transmitting unit 12 of) newly issues (generates) a tracking identifier based on the information received in step S2, and the issued tracking identifier is sent as a response ( to the advertiser system). The (transmitting unit 12 of) the tracking system 10 may store (save) the (issued) tracking identifier in a form linked to the information received in step S2. When returning the tracking identifier, the tracking system 10 (the transmitting unit 12 thereof) may also return the identification information received in step S2.

In step S4 (store tracking identifier), the advertiser system stores (manages) the information received in step S3. More specifically, it may be stored in the storage area of the server of the advertisement site, may be stored in the storage area of the general user's browser, or may be stored in both (regardless of the management location). ). Also, the advertiser system may store the tracking identifier received in step S3, or may store the tracking identifier and the identification information received in step S3 in association with each other.

In step S5 (intra-site transition), the general user transits to the advertiser CV page through in-site transition. Such transitions include revisiting after exiting (advertising site).

In step S6 (retrieving the tracking identifier), following the transition in step S5, the CV measurement tag or CV measurement system installed at the time of conversion acquires the tracking identifier stored in step S4. The identification information stored in step S4 may also be acquired. That is, the CV metrology tag or CV metrology system may obtain the tracking identifier and identification information stored in step S4.

In step S7 (CV notification), the CV measurement tag or CV measurement system transmits conversion data regarding conversion to the tracking system 10 . The conversion data includes the following information (some or all of the information may be absent).
- Tracking identifier (obtained in step S6)
・Order information (information related to orders associated with conversions; contract information)
- Identification information (acquired in step S6. Newly acquired information for reporting may be used. Not used for tracking determination)

Any means of transmission of conversion data is acceptable. More specifically, http (Hypertext Transfer Protocol) communication or https (Hypertext Transfer Protocol Secure) communication, SCP (Secure Copy Protocol) for files, SFTP (SSH File Transfer Protocol), or other protocol differences do not matter. .

After step S7, the receiving unit 13 of the tracking system 10 receives the information transmitted in step S7, and the executing unit 14 of the tracking system 10 executes tracking based on the received tracking identifier. More specifically, if the tracking identifier issued (generated) and stored (recorded) in step S3 by the execution unit 14 of the tracking system 10 matches the tracking identifier received in step S7, the conversion is normal. Record as
