Abstract

A system and method for efficiently executing a plurality of live parallel Internet content usage experiments using a large pool of randomly selected participating users (separated into control and test groups) while minimally disturbing offered content is provided. In an illustrative implementation, a content provider communicates the parameters for a content usage experiment to a content server. A complimentary test subject verification script operates on the content server that determines which client computing devices are to be included in the experiment group. In operation, a participating client computing device requests content from the content provider'"'"'s server. The content provider'"'"'s server executes the test subject verification script to determine if the client computing device is to be considered as a test subject. The content usage of the experiment content and non-experiment content is tracked and compared to each other to determine if the experiment content impacted content usage.

Claims

1. A method of executing a plurality of live content usage experiments comprising the acts of:

providing a unique identification tag to a content requesting client computing device by a content server;

processing said unique identification tag upon receiving a request for content from said client computing device by said content server to verify if said client computing device is a test subject; and

offering experiment content to said client computing device if said client computing device is verified as a test subject.

2. The method recited in claim 1, wherein said act of providing unique identification tag further comprises the acts of determining if said requesting client computing device has a unique identification tag and assigning a new unique identification tag to said client computing device if said client computing device does not have a unique identification tag.

3. The method recited in claim 2, wherein said determining act comprises processing COOKIES that are part of HTTP headers communicated as part of requests for content by said client computing devices.

4. The method recited in claim 1, wherein said processing step further comprises the acts of performing a hashing function on said received unique identification tags to produce an integer and comparing said integer with a predefined range to verify if said requesting client computing device is a test subjects

7. The method recited in claim 1, wherein said providing, processing, and offering acts are performed by a content application operating on said content server communicating with said client computing devices, said content application cooperating with at least one configuration file having pre-defined content usage experiment parameters and at least one server side object that performs the verification of test subjects.

8. The method recited in claim 7, wherein said communicating act is realized through a communications network comprising any of a fixed-wire LAN, a wireless LAN, a fixed-wire WAN, a wireless WAN, a fixed-wire intranet, a wireless intranet, and the Internet.

9. A computer-readable medium bearing computer-readable instructions for instructing a computer to carry out the acts recited in claim 1.

5. The method recited in claim I further comprising the acts of:

tracking content usage by said content server for experiment and non-experiment content

offered to produce content usage data; and

analyzing said content usage data to compare content usage of experiment content versus non-experiment data to produce data indicative of whether experiment content was more often used than non-experiment content.

6. The method recited in claim 5, further comprising the act of incorporating said analyzed experiment content into non-experiment content if said data indicates said analyzed experiment content was more often used.

10. A method to execute live content usage experiments comprising the acts of:

requesting content by at least one client computing device, said at least one client computing device cooperating with a content server over a communications network; and

receiving content by said at least one client computing device from said content server, said content being experiment content if said at least one client computing device is verified by said content server as a test subject.

11. The method recited in claim 10, wherein said requesting act comprises sending a request by said at least one client computing device to said content server, said request comprising a header having data indicative of said client computing device.

12. The method recited in claim 11, wherein said sending act comprises attaching COOKIES to said request, said COOKIES comprising a unique identification tag that may be used by said content server to verify if said at least one client computing device is a test subject.

13. The method recited in claim 10, further comprising the acts of tracking content usage for said received content by said at least one computing device and communicating said content usage information by said at least one client computing device to said content server.

14. The method recited in claim 13, wherein said requesting and receiving acts are performed by a computing application operating on said at least one client computing device, said computing application having an interface to procure requests for content and to display received content.

15. A computer-readable medium bearing computer-readable instructions for instructing a computer to carry out the acts recited in claim 10.

17. The system recited in claim 16, wherein said content usage experiment system receives requests for content from a client computing device, said content usage experiment processing said requests for content to determine if said client computing device has an assigned unique identification tag and executing said computing application to perform said test subject verification processes to determine if said client computing device is to be a test subject.

18. The system recited in claim 17, wherein said computing application comprises a server side object that receives said unique identification tag of said client computing device as input and performs a hashing function to produce an integer, said server side object using comparing said integer to a pre-defined range to determine if said client computing device is to be a test subject.

19. The system recited in claim 18, wherein said server side object uses a hash divisor to perform said hashing function.

20. The system recited in claim 18, wherein said experiment content is communicated by said content usage experiment system to said client computing device that is determined to be said test subject.

21. The system recited in claim 20, wherein said experiment content is only communicated by said content usage experiment system to said client computing device if the experiment to which the experiment content is associated has not expired.

22. The system recited in claim 16, wherein said content usage data for said content communicated to said client computing device is tracked and stored by said content usage experiment system.

23. The system recited in claim 22, wherein said tracked and stored content usage data is analyzed by said content usage experiment system to determine the efficacy of experiment content.
