Core Web Vitals Issue – Google Update for Improved Site Speed and Better User Experience

Core Web Vitals Assessment is a major Google Update to enhance the user experience by evaluating website page speed based on user experience and website responsiveness. It considers mainly three metrics/parameters to measure a site’s speed and user experience.

  1. Largest Contentful paint (LCP) – It is a page-load metric used to identify page load speed for better user experience by calculating the loading speed of the largest contentful module or element on a website’s page.
  2. First Input Delay (FID) – This is calculated based on user interaction with the website for the first time, i.e. the first time a user clicks on a website’s element such as a button or link to view and how much time the browser takes to respond to the user move.
  3. Cumulative Layout Shift – It refers to the shifting of the elements of a website after loading, calculating the cumulative time all the shifting elements took within 500ms of the user interaction with the website.

If your website passes all the three above-mentioned measures, then your website is considered to pass the Core Web Vitals assessment.
