What are Core Web Vitals?

Core Web Vitals are a set of measurable signals Google uses to assess the user experience of a web page, focusing on loading speed, interactivity and visual stability. They are an official ranking factor: pages that score well on them offer a better experience and have a slight edge in the search results.

The three Core Web Vitals

There are three metrics: LCP (Largest Contentful Paint) measures how quickly the main content loads, INP (Interaction to Next Paint) measures how quickly the page responds to interaction, and CLS (Cumulative Layout Shift) measures how stable the layout is while loading. Together they give a picture of perceived speed and smoothness.

Why are Core Web Vitals important?

A slow or jumpy page drives visitors away and costs conversions. Because Google takes these signals into account, they directly affect your SEO. They are a measurable part of technical SEO.

Improving Core Web Vitals

Common improvements are compressing images, cutting down heavy scripts, caching and reserving space for elements to prevent layout shifts. You measure your loading time with tools such as Google PageSpeed Insights. Background information is in the Google Search documentation.

Where do I measure my Core Web Vitals?

In Google Search Console and with PageSpeed Insights you see your scores and concrete points to improve.

How much weight do they carry?

They are a ranking factor, but relevance and content remain decisive. See them as an important precondition.
