Core Web Vitals

What are Core Web Vitals?

Core Web Vitals are user-focused metrics that Google uses to measure the overall user experience of web pages. These metrics are designed to help site owners and developers identify areas where they can improve the user experience of their websites, particularly in relation to page speed, responsiveness, and visual stability. 

The 3 Core Web Vitals metrics:

• Largest Contentful Paint (LCP): This measures how long it takes for the largest piece of content on a web page (usually an image or video) to load and become visible to the user. Google recommends that LCP should be less than 2.5 seconds for a good user experience. 
  

• Cumulative Layout Shift (CLS): This measures how much a web page's visual layout shifts or jumps around during the loading process. A low CLS score means that the visual layout of the page remains stable during loading. A good CLS score is less than 0.1. 

• Interaction to Next Paint (INP): This new metric assesses a web page's overall responsiveness to user interactions by measuring the latency of all interactions throughout the page's lifecycle. Unlike the now-retired FID metric (First Input Delay) which only measures the first interaction, INP captures a more complete picture of the site's responsiveness. A good INP score is less than 200 milliseconds.

These metrics are important because they directly impact user experience as well as SEO rankings – both of which, if optimized, will drive traffic, engagement, and conversion rates.
