Website speed and Core Web Vitals

What these metrics measure and which improvements tend to work.

A slow website frustrates visitors. Core Web Vitals are Google metrics covering the real experience of loading and interaction.

What they measure

LCP measures how long the main content takes to appear, INP how quickly the page responds and CLS unexpected layout shifts.

How to check

PageSpeed Insights and Search Console are free. Focus on real-user data on mobile.

Common improvements

Optimise images, reduce third-party scripts, reserve space for elements and use good hosting.

Without obsessing

Speed helps, but it does not replace useful content. Aim for a good experience, not a perfect score.
