Before configuring it, enable the option Session Replay, scroll map, form analysis on the Tag tab.
Session Replay technology offers an entirely new level of detail for analyzing the behavior of site users. You can replay user actions exactly as they occurred, to see what happens on each page and how users navigate, right down to every mouse movement, keystroke and click.
Detailed analysis of user behavior helps site owners to iron out navigation and usability problems and increase the site conversion rate.
