Have you heard of Web Vitals and specifically about the FCP metric? Tell us what you know about Web Vitals metrics.

Web Vitals are a set of key metrics from Google that help assess the quality of user experience on a web page.

FCP (First Contentful Paint) is one such metric, measuring the time from the start of page loading to the moment when the browser renders the first content element (text, image, SVG, etc.). This is an important indicator showing how quickly users see the first visual elements.

Other main Web Vitals metrics:

• LCP (Largest Contentful Paint) — the time from loading to the display of the largest visible element.
• FID (First Input Delay) — the delay in response to the first user interaction.
• CLS (Cumulative Layout Shift) — the total shift of page elements, affecting interface stability.

Using Web Vitals helps optimize performance and improve user perception of the site.
