Core Web Vitals Deep Dive
Welcome to a deeper look into the Core Web Vitals! These metrics are crucial for understanding and improving your website's user experience.
In this lesson, we'll analyze Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). You'll learn what each measures, why they matter, and practical techniques to optimize them.
Largest Contentful Paint (LCP)
Largest Contentful Paint (LCP) measures the time it takes for the largest content element visible within the viewport to render. Think of it as how quickly a user sees the main content of your page.
- A good LCP score is 2.5 seconds or less.
- Anything above 4 seconds is considered poor.
LCP is a key indicator of your page's perceived loading speed.
