Javascript Track Time Spent on Page

One of the key metrics for measuring the performance and engagement of a website is the time spent by the user on each webpage or the entire website. This metric can help us understand how well our content is attracting and retaining the user's attention. In this tutorial, we will learn how to track or measure time spent by user on webpage or website using JavaScript. We will use the window.performance API.

 let pageLoadTime = window.performance.now();
 intervalId = setInterval(() => {
  if (isActive) {
   const currentTime = window.performance.now();
   time = currentTime - pageLoadTime;
   updateFormattedTime();
  }
 }, 1000);
 document.addEventListener("visibilitychange", () => {
  isActive = !document.hidden;
  if (isActive) {
   pageLoadTime = window.performance.now() - time;
