The HTML item type allows you to present HTML and other "browser-compatible" files. The WebTracker item extends this functionality by tracking a subject's behaviour while browsing through a sequence of HTML or other browser-compatible files. It stores each link that the subject follows as well as the time at which the link was followed and how long the subject stayed there before continuing to the next link. The item ends when the subject clicks the "Continue" button. These data are all written to a separate spreadsheet file (.csv) that will be named after the variable name you assigned to the WebTracker item and will be located in the experiment's data folder.
