Core Web Vitals, explained without the technical fog.

Speed, responsiveness and visual stability affect how easy your website is to use.

LCP: show the main content quickly.

Largest Contentful Paint measures when the largest important content element is rendered. Large hero images, slow hosting or blocking styles can make the first view feel slow.

INP: respond when someone interacts.

Interaction to Next Paint tracks responsiveness. A page should not freeze when a visitor opens the menu, fills a form or taps a button. Heavy JavaScript can make simple actions feel delayed.

CLS: stop the page jumping.

Cumulative Layout Shift measures unexpected movement. Images without dimensions, late-loading elements and changing font sizes can push buttons out of place. That is frustrating, especially on mobile.

Good practices before chasing a score.

Compress images. Reserve space for media. Load only useful scripts. Use readable fonts. Test real user tasks. Lab tools are helpful, but do not let a green score hide a broken contact form.

Use the right measurement tools.

PageSpeed Insights and Search Console can help identify problems. Compare mobile and desktop experiences and prioritise pages that customers actually use.

What to do next

Choose the highest-impact issue you can verify. Write down the current state, make one clear improvement and review what changed. A useful audit should lead to action, not a longer to-do list nobody owns.
