What are Core Web Vitals?

Core Web Vitals are a set of metrics related to Speed, Interactivity and Visual Stability.


Google has defined the following as the Core Web Vitals:

  • Largest Contentful Paint (LCP). The amount of time it takes for a page’s main content to load. The ideal LCP should occur within 2.4 seconds from the moment the page first starts loading.
  • First Input Delay (FID). The amount of time required for a page to become interactive. A perfect measurement is less than 100 milliseconds.
  • Cumulative Layout Shift (CLS). The number of unexpected layout shifts of visual page content. The ideal measurement is less than 0.1.

This set of metrics was designed to help us to measure the user experience when it comes to the page loading speed, interactivity, and visual stability.

Site Owners and SEO specialists can focus on these metrics to deliver a better user experience and improve SEO.

Will it affect the rankings in the Google Search Engine?

Yes. If Google determines that a page provides a high-quality user experience based on its page experience signal, the page will most likely be ranked higher in search engines.

However, content relevance is still one of the essential factors when it comes to rankings. A page with highly relevant content to a query may rank well even if it has a low page experience signal.

Well, ideally it should achieve both: provide highly relevant content and high page experience signal.

Fix User Experience with a Core Web Vitals report

Google has introduced a Core Web Vitals report to show how good your page performance is based on real-world usage data (also known as field data).

The Core Web vitals report only shows URL performance grouped by status, metric type and URL group (groups of similar web pages).

Your URLs must be indexed and only appear in this report. The report will be based on three metrics mentioned earlier.

When a URL reaches a certain amount of data for any metric, the page status is the status of its worst-performing metric.


Steps to navigate the report

  1. Toggle the Poor, Needs Improvement or Good tabs on the overview page chart. You can see how URLs on your site perform based on historical user data.
  2. Click “Open Report”. You are able to see the mobile or desktop summary page, showing page performance numbers for each platform.
  3. Click a row in the table to see details. All about URL groups affected by the selected issues including a set of example URLs.
  4. Click a URL in the Example table of the issues details page. You are able to see more information related to URLs and similar URLs.

Other user experience signals

SEOs and site owners can also measure the other type of user experience signals:


  1. Mobile Friendliness: Evaluate web performance on mobile devices. Use Google’s mobile-friendly test.
  2. Safe Browsing. Ensure the URLs against Google’s are constantly updated of unsafe web resources. Check the Security Issues report in Search Console for any issues with safe browsing.
  3. HTTPS: An authentication and security protocol implemented in browsers. For pages that load over a secure HTTPS connection, it will display a lock icon in the browser address bar. The URL will begin with HTTPS.
  4. No instructive interstitials. Ensure no blocking or popup ads on almost or all the page as this can lead to a bad user experience for desktop and mobile users alike.
