User activity tracking is the process of monitoring, collecting, and analyzing visitor browsing
behavior on a website or app.
The easiest and most popular way to start tracking website users is to set up Google Analytics
(we'll show you how below). But Google Analytics (GA) can be equal parts overwhelming and
limited: it’s packed with options but will only show you what happens on your site, not why.
Tracking scroll depth gives you this power, providing actionable insights to improve the
user experience (UX) by revealing your site visitors’ scrolling behavior.
