Google’s Page Experience search depends on three performance-based metrics called Core Web Vitals. These metrics are Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), First Input Delay (FID).

Page Experience is a Google Search ranking factor that calculates the quality of a website page user experience such as the page’s mobile-friendliness, accessibility, and more, how quickly the page loads, how well the page content renders in web browsers.

Core Web Vitals are measured with the help of field data collected from Google Chrome User Experience. If you want to optimize you have to know each of the three metrics that make the Core Web Vitals.  

Cumulative Layout Shift 

The amount that makes the elements move unexpectedly on a site. This factor is to gauge usability than speed. An e-commerce site can have a banner at the top of a page with a discount code or offer. If that bar appears after the page first starts loading, it can push down the rest of the content and cause frustration for the users who are trying to read the content on the page. 


First Input Delay 

A user’s first impression is impacted by the speed of the site. Your e-commerce site needs to be responsive once your user tries to interact with it. First Input Delay, or FID, measures the time when a user first opens the page to the time when the browser can give the responses after the user has asked for a response like opening some product after clicking, or tapping or pressing a key. 

An input delay occurs because of JavaScript. This means that when the browser comes across a JavaScript file, it must pause what it is going to download. The longer this process takes, the more delay a user experience, and the less will be the ranking of this site on Google. Google finds FID 100 milliseconds or less fast and is between 1.1- and 3.0-seconds low. Google recommends looking for FID on mobile and desktop, as this will represent the worst user experience and verify the areas where improvement is needed.  

There are some common reasons for slow FID like: 

  1. Long tasks blocking the main thread for 50 milliseconds and more.  
  2. First party script delaying interaction readiness 
  3. Heavy JavaScript execution time 
  4. Largest Contentful Paint (LCP)

  1. Improve your Server Response Time – Long server response time can make your SEO and UX poor. A faster server response time improves the page load metric.
