What Are Google Web Core Vitals?
A while back, Google announced they would be introducing a new ranking factor in 2021. This new factor is page experience, and it is at the center of Google’s Core Web Vitals, along with a few other metrics for measuring user experience. These three things are vital for building awesome websites. Let us take a look at them in-depth.
Core Web Vitals - What is This New Thing?
Core Web Vitals are a subset of factors that Google has chosen to measure overall user experience. They represent one facet of the user experience, which Google takes very seriously. If a user has a poor experience due to slow loading times, they may not stay on the page, resulting in a loss of revenue and a low-ranking score.
These are not the only factors involved. Google has said there are others as well. But it considers these three factors to be important for ranking webpages, so it’s vital that you know what they are and how they affect you.
The 3 Core Web Vitals are:
● LCP, Largest Contentful Paint: This measures loading times for text and images. To hit the mark, 75% of your website’s content must load in less than 2.5 seconds. It’s very frustrating to wait for pages to load completely. A site that loads too slowly will not rank as well.
● FID, or First Input Delay: This measures how long it takes for the site to become interactive. Meaning, how quickly it reacts when a user clicks a button. A good score is 100 ms. while a poor score is 300 ms.
● CLS, or Cumulative Layout Shift: This measures the visual stability of your website. This means whether or not items move around on the page while it is loading. If the user is trying to click a button to read something and the button keeps moving, it is very frustrating and the visitor is likely to leave.
Why Are Core Web Vitals Important?
Page experience will consist of some of these factors, as well as a few others, for an overall measurement of how well your website performs when someone visits your page. User experience will be a determining factor in whether your website reaches the number one spot or not. A website that is designed poorly with no focus on the user experience won’t make the cut.
When it comes to search visibility, having great content and a good page experience score will help you stand out in a sea of pages with similar content. If your site loads fast and visitors stay on the page, your site is likely to appear closer to the top of SERPs.
Although it is an important factor, a great page experience score won’t automatically guarantee you the #1 spot in Google search pages. Google has said that page experience is one of 200 factors that they used to rank sites in search. So, it is not a magic pill that will push you to the top. It’s a very important part of your ranking score that will determine if your website is in the first few pages, or the last page of search results.
A Few Other Factors That Affect Core Web Vitals Score:
● HTTPS encryption
● Mobile friendliness
● Lack of interstitial pop ups
● Safe browsing
Where to Find Your Site Stats?

If you want to see how well your site is performing in relation to Core Web Vitals, Google has some useful tools to help you analyze your website’s vital signs and give it a check-up to stay relevant and up to speed with the new algorithm.
These include:
● Search Console

● Lighthouse
● Chrome DevTools
● Chrome UX Report
● Web Vitals Extension
You can use any of these tools to measure Core Web Vitals. Each one looks at a different aspect of your website, so you can use one or more to get a good picture of your site stacks up to the new recommendations.
