This metric measures the percentage of users who left the website from the page we are tracking—the ratio of sessions in which the last page was the one we are measuring.
It's easy; the exit page of a site and a session is the last one that was seen in that session. It can help us determine which pages are causing the abandonment of our users. It could be a page where the navigation is confusing or where the content does not correspond to what the title promises, or simply is not of quality.
