Core Web Vitals

Google uses real-world user data to measure how fast and smooth your website is. If you fail these tests, your rankings will suffer.

The Big Three Metrics

Core Web Vitals boil down to three specific measurements of user experience:

  • LCP (Largest Contentful Paint): Loading speed. How long it takes for the largest image or text block to become visible.
  • FID / INP (Interaction to Next Paint): Interactivity. How quickly the page responds when a user clicks a button.
  • CLS (Cumulative Layout Shift): Visual stability. Does the page content jump around as images load?

Why It Matters

Search engines want to send users to sites that provide a good experience. Even if your content is perfect, a slow, jumpy site will be outranked by a faster competitor.

How to Fix It

  1. Optimize Images: Compress and serve images in modern formats like WebP.
  2. Minimize JavaScript: Defer non-critical scripts so the main content loads first.
  3. Set Dimensions: Always specify width and height on images to prevent layout shifts (CLS).
