A/B Testing

A method comprising:

• sending, by a client computer system to one or more server computer systems, a request for an electronic communication which is subject to a test to identify factors that affect usability of the electronic communication;
• receiving, by the client computer system from the one or more server computer systems, a version of the electronic communication;
• wherein the received version of the electronic communication comprises at least one of a first version of an electronic communication that satisfies the request with the first version promoting identification of first factors that affect the usability, or a second, different version of the electronic communication that satisfies the request, with the second version promoting identification of second, different factors that affect the usability;
• and
• sending, by the client computer system to the one or more server computer systems, one or more responses to the received electronic communication to promote identification by the one or more server computer systems of one or more factors that increase the usability of the requested electronic communication relative to the usability of the requested electronic communication based on other factors.

One or more machine-readable hardware storage devices storing instructions that are executable by one or more processing devices of a client computer system to perform operations comprising:

• sending, by the client computer system to one or more server computer systems, a request for an electronic communication which is subject to a test to identify factors that affect usability of the electronic communication;
• receiving, by the client computer system from the one or more server computer systems, a version of the electronic communication;
• wherein the received version of the electronic communication comprises at least one of a first version of an electronic communication that satisfies the request with the first version promoting identification of first factors that affect the usability, or a second, different version of the electronic communication that satisfies the request, with the second version promoting identification of second, different factors that affect the usability;
• and
• sending, by the client computer system to the one or more server computer systems, one or more responses to the received electronic communication to promote identification by the one or more server computer systems of one or more factors that increase the usability of the requested electronic communication relative to the usability of the requested electronic communication based on other factors.
