Statistical marketing attribution correlation

A computer program product, comprising:

• a computer readable storage medium having computer readable program code embodied therewith, where the computer readable storage medium is not a transitory signal per se and where the computer readable program code when executed on a network analytics computer causes the network analytics computer to:
• improve computer detection of different server access channels that originate a plurality of web access sessions at different times with different servers that do not result during the respective web access sessions in placement of an order for a particular Internet-advertised product or service, where the different server access channels are selected from a group consisting of a manufacturer's server access channel, an email-based promotional campaign server access channel, a manufacturer affiliate's server access channel, a coupon distribution server access channel, and a pay-per-click advertising server access channel;
• and
• where the improved computer detection of the different server access channels that do not result during the respective web access sessions in the placement of the order for the particular Internet-advertised product or service comprises the computer readable program code when executed on the network analytics computer causing the network analytics computer, responsive to detecting a first web access session originated by a consumer device using a first server access channel to access information related to the particular Internet-advertised product or service, to iterate until the order is placed to:
• deploy, in association with each of the plurality of web access sessions initiated by the consumer device to access additional information related to the particular Internet-advertised product or service, a distinct session cookie that uniquely identifies session information comprising (i) a session identifier of the web access session, and (ii) a session-originating server access channel identifier of the server access channel that originated the web access session;
• and
• capture integrated server access channel correlation information across the plurality of web access sessions comprising the session information identified within each distinct session cookie that documents each of the plurality of web access sessions with the different servers that do not result during the respective web access sessions in the placement of the order and that are originated at the different times by the consumer device using the different server access channels;
• where the computer readable program code when executed on the network analytics computer further causes the network analytics computer, in response to the consumer device placing the order for the particular Internet-advertised product or service via a web sales-capable server, to:
• update server access channel information, based upon the captured integrated server access channel correlation information, comprising updating a respective one of a first server access channel accumulated statistical historical effectiveness metric of the first server access channel that originated the first web access session that did not result during the first web access session in the placement of the order, a middle server access channel accumulated statistical historical effectiveness metric of each middle server access channel that originated each middle web access session that did not result during the middle web access sessions in the placement of the order, and a last server access channel accumulated statistical historical effectiveness metric of a last server access channel that originated a last web access session that did result during the last web access sessions in the placement of the order, where the detection of the different server access channels that did not result during the respective web access sessions in the placement of the order is improved.
