Why Core Web Vitals matter

Core web vitals are a set of metrics that measure the real-world experience of users on your website. They are important to providing a good user experience to your users which may be the deciding factor to whether customers stay on your website or leave to go to another site. Core web vitals are particularly important to mobile users as 80% of users abandon a website if it doesn’t display correctly on their phone.

What are the core web vitals?

There are four core web vitals:

  • Largest contentful paint (LCP) measures the time it takes for the largest content element on your website to load and become visible to the user. For example, how quick the main image as you click onto your website takes to load.
  • First Input Delay (FID) measures the length of time it takes for the browser to respond to an interaction such as clicking on a link or pressing a button.
  • Cumulative layout shift (CLS) measures how stable your website is visually. If your website has any unexpected layout shifts, it can annoy the user giving them a bad user experience when on your website.
  • Interaction to next paint (INP) assesses a page’s overall responsiveness to the user’s interactions. It measures the time that it takes for the page to respond to all click, tap, and keyboard interactions.

How to Measure Core Web Vitals

There are a number of tools you can use to measure your core web vitals, including:

  • Google Search Console
  • PageSpeed Insights
  • GTmetrix

Once you have measured all of your core web vitals, you can then use this data to help improve your website!
