Core Web Vitals

Set of Google metrics for load speed, interactivity and visual stability that measures how smoothly your page feels to visitors.

By Tanguy De Keyzer · Founder & digital strategist

Core Web Vitals are a set of Google metrics that assess how smoothly a page feels to your visitor: how fast the main content loads, how quickly the page responds to interaction and how stable the layout stays during loading.

Which three values count?

The Core Web Vitals consist of three concrete signals that each measure a part of the user experience. Together they give an honest picture of how pleasant your site actually works on a visitor’s screen.

  • LCP (Largest Contentful Paint): how fast the largest visible element appears
  • INP (Interaction to Next Paint): how quickly the page responds to clicks and taps
  • CLS (Cumulative Layout Shift): how stable the layout stays without shifting elements

Why are they important for SEO?

Google uses these values as part of its page experience signals, which means a slow or jumpy site has a harder time ranking. But the effect reaches further than positions alone. A visitor who wants to click a button that suddenly jumps away, or who has to wait seconds, drops off. Working on your page speed and on these vitals therefore improves not only your findability, but also your conversion.

Core Web Vitals according to Customer Impact

We treat Core Web Vitals as a means, not a goal. A perfect score is nice, but only counts if it translates into fewer drop-offs and more requests. For B2B sites we therefore look at the pages that matter commercially: your service pages and landing pages. There we make sure the technique, such as lazy loading of heavy images, speeds up the experience without weakening the message. Fast pages that hold visitors ultimately produce customers. That is what we steer on.

From theory to growth.

We turn Core Web Vitals into measurable results for your business.
