Core Web Vitals

A set of specific metrics that Google uses to measure the user experience of a website. These metrics quantify web performance and user interaction with a website. Core Web Vitals focus on three key areas:

1. Largest Contentful Paint (LCP): LCP measures the time it takes for the largest content element, such as an image or a block of text, to become visible to the user. It indicates how quickly the main content of a webpage is loaded and helps assess perceived loading speed.
2. First Input Delay (FID): FID measures the time delay between a user’s first interaction, such as clicking a button or link, and the browser’s response. It reflects the website’s responsiveness and interactivity.
3. Cumulative Layout Shift (CLS): CLS measures the visual stability of a webpage. It quantifies how much the layout shifts or changes unexpectedly during loading. Layout shifts can frustrate users, especially when they lead to unintended clicks or other user interface issues.

Google considers these metrics crucial for determining a website’s overall user experience and has incorporated them into its ranking algorithm. Websites that provide better experiences regarding loading speed, interactivity, and visual stability are more likely to rank higher in search results. Web developers and site owners are encouraged to optimize their websites to improve these Core Web Vitals for a better user experience and search engine visibility.
