Audience configuration panel
Configure the traffic allocation
Traffic allocation is used to define how the participants in the experiment are split between the control path and the variant path. This defaults to a 50/50 split, but you can change this by entering a different value for either Control (%) or Variant (%). If you change one of these values, the other automatically changes to ensure that the traffic allocation adds up to 100%
Configure the target audience
You can use the target audience section to refine which visitors should be included as participants in the experiment. The following options are available to configure the target audience:
Targeting Method: This allows you to decide whether to use layout targeting or URL targeting.
Layout Name: If you select layout from the Targeting Method box, this field displays the layout name used for layout targeting.
URL Targeting: If you select URL from the Targeting Method box, this area displays two further options that you can use to configure the target audience:
Included URL: This is a text box where you can enter a string to use perform a match against the current page URL.
Match Type: This lets you decide what kind of match you wish to perform. If you select Regular Expression from the Match Type dropdown, then you can use the Included URL textbox to provide the RegEx query you wish to run.
