Once you install the javascript code in the head and foot on the site pages, your never have to paste any more code on your site. Even creating test variations does not require any additional code being placed on test pages.
With the javascript code in place, the software will track all visits to your site at the event level. This means it records mouse movements, time on page, scrolling, clicking, playing of videos or audios and much more. You will also be able to create test variations and run the test without placing any additional code on the site.
