Abstract: A variation testing system for performing variation testing of content is disclosed. The variation testing system allows an experimenter to continuously monitor the results of the variation test. In order to ensure that the experimenter is provided with valid results, the variation testing system may reset the variation test.

Abstract: A content variation experiment system for performing variation testing of web pages is disclosed. A content provider receives requests for a web page undergoing an experiment. The content provider determines a variation from a plurality of variations of the web page to provide to the user. The content provider makes the determination without sending a network request to an experiment definition system used to define the experiment thereby reducing network latency.

Abstract: Webpages are optimizing through the use of experiments that compare the responses of viewers that are either presented with the original webpage or a variant thereof. One or more variants are first defined through the use of a browser-based editor application that initially examines the webpage for a snippet of code. The snippet can be added to the webpage, if missing, and the webpage returned to the editor application. Changes made to the webpage to define a variant are saved in variation code. When the webpage is later requested by multiple viewers, in each instance the viewer receives the webpage with the snippet, the snippet instructs the browser to download a file, and the instructions of the file determine whether the viewer will see the variant or the original webpage. Tracking viewer responses to the webpage and the variant allow a statistical basis for comparison to be developed.
