Key Statistics about Core Web Vitals

Key Statistics about Core Web Vitals

Google’s Core Web Vitals is the new template to interpret all digital processes when talking about websites and web performance.

Key Statistics about Core Web VitalsGetting to grips with Core Web Vitals helps a business figure out their current website performance and pinpoint those areas in which they are lagging behind. But it’s not only the concentration on a company’s own website that will give them insight into where to improve but also the broader perspective of Core Web Vitals; the more general performance of the metrics across millions of websites across the world.

It’s this latter point to which we’re going to focus on now. To give a broader and overall view of Core Web Vitals, let’s look at some statistics that are focused on the general performance of Core Web Vitals as well as a breakdown of each of the three metrics.

General statistics

Despite Core Web Vitals being fairly new, fortunately Google Chrome releases a UX report each month that highlights key statistics based on more than 1 million websites.

Some of the more important general Core Web Vitals statistics include the following:

  • Only 22% of websites passed all three metrics with good scores: Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift.
  • South Korea is home to the highest number of websites that pass Core Web Vitals scores.
  • In the US, just 53.7% of websites have a good score when it comes to Largest Contentful Paint.
  • Managed WordPress Hosting services have better Core Web Vitals scores than Shared hosting.
  • In the UK, just 29% of websites are not fast enough to pass Core Web Vitals.
  • The use of a content delivery network has a beneficial impact on overall Core Web Vitals scores.
  • 70.4% of websites have a good score for Largest Contentful Paint on desktop/laptop yet only 60.1% of websites have a good score on mobile. 

Largest Contentful Paint statistics

Detected through Google Chrome’s monthly report, here are a few of the more interesting statistics about one of the Core Web Vitals.

  • Largest Contentful Paint scores in the UK improved month on month, going from 73% to 75% of websites scoring well.
  • 55.4% of websites have a good score in Largest Contentful Paint.
  • 29.6% of websites have a moderate score in Largest Contentful Paint.
  • 15.1% of websites have a poor score in Largest Contentful Paint.
  • Among the top 20,000 websites, 66% of pages have a good score with 26.4% of websites needing improvement.

First Input Delay

Detected through Google Chrome’s monthly report, here are a few of the more interesting statistics about First Input Delay.

  • First Input Delay is the easier of the Core Web Vitals metrics to obtain a good score.
  • The top 100 websites have a 100% score when it comes to First Input Delay when controlled for desktop experience
  • The top 10,000 websites have a score of 99.8% when controlled for desktop experience.
  • On mobile, however, 87.4% of websites have a good First Input Delay score (less than 100 milliseconds).

Cumulative Layout Shift

Key Statistics about Core Web VitalsDetected through Google Chrome’s monthly report, here are a few of the more interesting statistics about Cumulative Layout Shift – perhaps the most difficult Core Web Vitals to get a good score in.

  • 40.9% of the top 1,000 websites have a good Cumulative Layout Shift score.
  • 35.9% of the top 1,000 websites have a poor Cumulative Layout Shift score.
  • Just 38.5% of websites have a good Cumulative Layout Shift score when controlled for 4G connections.
  • 31.9% of websites have poor scores when controlled for 4G connections.

The launch of Core Web Metrics by Google was the latest step in the tech company’s move towards elevating online experience for users and laying out a blueprint for businesses in which areas are to be prioritized. Hopefully these stacks of stats can go somewhere into familiarizing the broader view of Core Web Vitals and what role they play in today’s digital experiences.
