Learn about the three Core Web Vitals: LCP, FID, and CLS

Google makes lots of small changes to its search algorithms all the time, many of them go un-official and some are announced. In May 2021, Google said that they will update their algorithms to integrate a new ranking factor called Core Web Vitals. Google developed a new set of metrics including Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift. These are the three main pillars of Google’s page experience update which means performance, responsiveness, and visual stability.

What Is Core Web Vitals?

Core Web Vital is a new tool of Google to measure the user experience of a web page. It will become one of the key ranking factors in search engine optimization. So the better the UX, the more likely you are to rank on Google.

Web Vitals VS PageSpeed Insights

For PageSpeed Insights, Google crawls your page themselves and uses software to create a report. But Core Web Vitals only measures the experience of real-world users. That makes it super accurate and a great tool for UX web page creation.

What Does Google Mean By A Good User Experience?

They take things like load time, interactivity, and visual stability into account when considering UX. Core Web Vitals is an initiative by Google to provide unified guidance for quality signals that are essential to delivering a great user experience on the web.

The three pillars of page experience:

Largest Contentful Paint (LCP): measures loading performance. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading.

First Input Delay (FID): measures interactivity. To provide a good user experience, pages should have an FID of less than 100 milliseconds.

Cumulative Layout Shift (CLS): measures visual stability. To provide a good user experience, pages should maintain a CLS of less than 0.1.

The Core Web Vitals Live Here:

You’ll see 2 line graphs, one for mobile traffic, the other for desktop traffic.

You need enough traffic from either platform for Google to generate these graphs

Red lines are bad. Your page loads slowly.

Yellow lines are okay. You could do better.

Green lines are good. Your page loads quickly.

You need enough traffic from either platform for Google to generate these graphs

Core Web Vitals Measuring Tools:

Here are a few tools you can use to help measure the Web Vitals of your webpage on your own:

• Google Search Console
• PageSpeed Insights
• Lighthouse
• Chrome User Experience Report
• Chrome DevTools

Bottom Line

Core Web Vitals is the new way of emphasizing user experience, and it’s a great tool for web marketers who may want deeper insight into their performance.
