Multi computing device network based conversion determination based on computer network traffic

A method of multi-computing device network based conversion determination based on computer network traffic, comprising:

• identifying, by a content selection computer server, a computer network based cross-device conversion associated with a first client computing device of a first set of client computing devices and a second client computing device of a second set of client computing devices, the first client computing device having accessed third party content associated with a third party content provider via a first computer network connection and the second client computing device having accessed a webpage of the third-party content provider associated with the third party content via a second computer network connection, and the first client computing device and the second client computing device both logged into a same online account;
• obtaining, by the content selection computer server, via a content tag associated with a script that executes on a webpage that includes the third party content, data indicating that the first client computing device accessed the third-party content;
• determining, by the content selection computer server, the computer network based cross-device conversion based on the data obtained via the content tag, and based on the second client computing device having accessed the webpage of the third-party content provider;
• determining, by the content selection computer server, a percentage of the first set of client computing devices and the second set of client computing devices that have logged into common respective online accounts;
• determining, by the content selection computer server, using an extrapolation technique, an estimated number of computer network based cross-device conversions based on the computer network based cross-device conversion associated with a first client computing device and the second client computing device, and based on the percentage of the first set of client computing devices and the second set of client computing devices that have logged into common respective online accounts;
• and
• providing, by the content selection computer server, an indication of the estimated number of computer network based cross-device conversions via a computer network to a third party content provider computing device for display by an electronic display of the third party content provider computing device.

A computer-readable storage medium having machine instructions stored therein, the instructions being executable by a processor to cause the processor to perform operations for multi-computing device network based conversion determination based on computer network traffic, the operations comprising:

• identifying a computer network based cross-device conversion associated with a first client computing device of a first set of client computing devices and a second client computing device of a second set of client computing devices, the first client computing device having accessed third party content associated with a third party content provider via a first computer network connection and the second client computing device having accessed a webpage of the third-party content provider associated with the third party content via a second computer network connection, and the first client computing device and the second client computing device both logged into a same online account;
• obtaining via a content tag associated with a script that executes on a webpage that includes the third party content, data indicating that the first client computing device accessed the third-party content;
• determining the computer network based cross-device conversion based on the data obtained via the content tag, and based on the second client computing device having accessed the webpage of the third-party content provider;
• determining a percentage of the first set of client computing devices and the second set of client computing devices that have logged into common respective online accounts;
• determining using an extrapolation technique, an estimated number of computer network based cross-device conversions based on the computer network based cross-device conversion associated with a first client computing device and the second client computing device, and based on the percentage of the first set of client computing devices and the second set of client computing devices that have logged into common respective online accounts;
• and
• providing an indication of the estimated number of computer network based cross-device conversions via a computer network to a third party content provider computing device for display by an electronic display of the third party content provider computing device.
