Core Web Vitals

February 21, 2023

Core Web Vitals are a set of metrics defined by Google that measure a website’s performance and user experience. These metrics focus on a webpage’s loading speed, interactivity, and visual stability. 

The Core Web Vitals include:

Largest Contentful Paint (LCP): Measures loading performance, it should occur within 2.5 seconds of when the page first starts loading.

First Input Delay (FID): Measures interactivity, it should be less than 100 milliseconds.

Cumulative Layout Shift (CLS): Measures visual stability, it should be less than 0.1.

Meeting the Core Web Vitals targets ensures the user can interact with the site quickly and with a stable layout. These metrics are important for both SEO and user experience. Google has announced that it plans to use core web vitals as a ranking factor in search results, so optimizing your website to meet these standards is important.

To improve the core web vitals, developers can take various actions such as reducing the size of images and other resources, implementing lazy loading, optimizing the code, and reducing the number of unnecessary scripts and styles.

Google Search Console and various third-party web vitals testing tools can be used to monitor and track the core web vitals of a website. These tools can help identify the specific issues that need to be addressed and guide how to fix them.
