Core Web Vitals
Introduction:
In recent years, the speed and performance of websites have become increasingly important. Google has recognized this and introduced the concept of Core Web Vitals. These are a set of metrics that measure critical aspects of user experience and help website owners and developers to optimize their sites for performance.
What are Core Web Vitals?
Core Web Vitals is a set of metrics that measure critical aspects of website user experience. They are part of Google’s overall effort to improve the performance and usability of the web. The metrics that makeup Core Web Vitals are designed to measure three key areas of user experience: loading, interactivity, and visual stability. These metrics are:
- Largest Contentful Paint (L.C.P.): This metric measures the loading speed of the most significant element on a web page, such as an image or a video.
- First Input Delay (FID): This metric measures the time it takes for a web page to respond to a user’s first interaction, such as clicking a button or a link.
- Cumulative Layout Shift (C.L.S.): This metric measures the visual stability of a web page or how much the layout of a page shifts while it is loading.
Why are Core Web Vitals Important?
Core Web Vitals are essential because they provide a standardized set of metrics that website owners and developers can use to measure the user experience of their sites. By optimizing for these metrics, website owners can ensure that their sites load quickly, respond to user interactions promptly, and maintain visual stability throughout the user’s session.
Furthermore, Core Web Vitals have become a part of Google’s overall ranking algorithm. This means that websites that perform well on these metrics are more likely to rank higher in search results than sites that do not.
How is Core Web Vitals Measured?
Core Web Vitals are measured using a combination of field data and lab data. Field data is collected from real users who visit a website and is used to measure the actual performance of a site in the wild. On the other hand, lab data is collected in a controlled environment and is used to test a site’s performance under ideal conditions.
To measure Core Web Vitals, website owners and developers can use various tools, including Google’s own PageSpeed Insights and Lighthouse and other third-party tools such as WebPageTest and GTmetrix.

Core Web Vitals Metrics:
Core Web Vitals is a set of metrics that measure critical aspects of website user experience. They are designed to measure three key areas of user experience: loading, interactivity, and visual stability. The three metrics that makeup Core Web Vitals are:
Largest Contentful Paint (L.C.P.):
The largest Contentful Paint measures the loading speed of the most significant element on a web page, such as an image or a video. It is an important metric because it measures the perceived loading speed of a page, which is the amount of time it takes for the page to appear fully loaded to the user. A good L.C.P. score is achieved when the most significant element on the page loads within 2.5 seconds of the page starting to pack.
First Input Delay (FID):
First, Input Delay measures the time it takes for a web page to respond to a user’s first interaction, such as clicking a button or a link. It is an important metric because it measures the responsiveness of a page to user input. A good FID score is achieved when a page responds to user input within 100 milliseconds.
Cumulative Layout Shift (C.L.S.):
Cumulative Layout Shift measures the visual stability of a web page or how much the layout of a page shifts while it is loading. It is an important metric because it measures how much layout shifts on a page disrupt the user’s experience. A good C.L.S. score is achieved when the page has a maximum layout shift of 0.1.
