Abstract: A system and a method for detecting and capturing information corresponding to split tests and their outcomes are disclosed. The system identifies a split test being run on a third-party website or web page. The split test comprises one or more experimental arms corresponding to modifications of the third-party website or web page. The system identifies the arms of the split test and monitors changes in traffic allocation to the arms of the split test. Further, the system identifies one or more experimental arms as being winner arms based on an increase in the traffic allocation to the arms or modifications contained in the arm or arms being detected on the website or web page following the conclusion of the test. In one embodiment, the system identifies one or more experimental arms as being winner arms when the traffic is allocated substantially or completely to the arms.
