Core Web Vitals: Everything You Need To Know

On Twitter, Google Search Central made an announcement that captured all the attention of a large number of people:

We’re announcing that page experience ranking signals for Google Search will launch in May 2021. This will combine Core Web Vitals and previous UX-related signals.

Those who do SEO and regularly need to check the website indexes on Google Search Console, you must have realized a change. The Speed and Report section of Google Search Console page disappeared, replaced by an item called Core Web Vitals report.

So what is Core Web Vitals and why was it chosen to become a Google ranking factor in the future? How do you make optimal use of Core Web Vitals for your website? All your questions will be answered in the article below.

What are Core Web Vitals?

Core Web Vitals is a collection of essential website metrics covering aspects related to the user experience on the page. Core Web Vitals are metrics measured by Chrome UX Report and Google Search Console to assess website performance and rank SEO scores.

Each metric represents an aspect of user experience, corresponding to the following ranking factors:

  • Loading: Page loading speed
  • Interactivity: Interoperability
  • Visual stability: Display stability

There are 4 indicators forming Core Web Vitals:

LCP (Largest Contentful Paint): LCP measures the Time to complete the main content that is first displayed when the page has finished loading. The ideal LCP should be at least 2.5 seconds.

FID (First Input Delay): The time the user responds to the first interaction on the website. The FID index needs to be optimized to get under 100 milliseconds.

CLS (Cumulate Layout Shift): The change score. Or it can be understood that this is an indicator of the volume of image layouts that are suddenly shifted on the website. The best CLS that each website needs to achieve for the best experience is no more than 0.1.

FCP (First Contentful Paint): The time is measured when a user sees the first visual response from the page. Faster times are more likely to keep users engaged with your website.

Why do Core Web Vitals Matter?

After spending more than 2 decades continuously educating and orienting webmasters to provide quality content, by 2021, Google now not only wants websites with expert content but the experience of that website must be optimized.

That’s why Core Web Vitals was born and raised its importance as SEO metrics. Moreover, if we go deeper into the survey data, you will easily notice the elements experience, including speed heavily influenced how the SEO results:

In general, expect to lose more than 37% of traffic if your website takes longer than 5 seconds to load. + Walmart discovered that just increasing their loading speed 1s faster, the conversion rate of that site also increased by more than 2%

The same thing with AutoAnything when they increased the speed by 50%, online sales also increased. increased to 11 – 12%.In general, everyone will love a website with fast speed and a smooth experience. This will help keep users longer, read your content more, and be more likely to buy.

Google announced that the signal about the on-page experience will become the deciding factor, in the case of websites with similar ratings for content quality.

Therefore, in addition to producing useful content with the right intention of customers, SEO’ers need to focus their resources on optimizing the experience (Page Experience & Core Web Vitals) and the Page Authority of the page before they can be applied and became key ranking factors.

Statistics from NYTimes Google Page Speed Insights.

If considered on mobile, the website does not pass Core Web Vital assessment because FCP and LCP are low. The reason is that too many ads appear to hide the content and unused JavaSript, causing the initial server response time to be high.

Step 1: Go to Google Search Console

Step 2: Click “Site Essentials” in the column Advanced Features
