What are Core Web Vitals?

Core Web Vitals are three essential metrics that Google uses to measure user experience on websites. They evaluate loading speed (LCP – Largest Contentful Paint), interactivity (INP – Interaction to Next Paint), and visual stability (CLS – Cumulative Layout Shift).

Since 2021, these metrics are an official Google ranking factor and significantly determine your visibility in search results. Websites with good Core Web Vitals not only rank higher but also provide visitors with a noticeably better experience.

Our tool analyzes all three metrics in detail and shows you precisely where optimization is needed.

Why a Google Speed Test Matters

Your website's loading speed directly impacts your conversion rate, bounce rate, and search engine ranking. Studies show: 53% of mobile users leave a page if it takes longer than 3 seconds to load.

Every additional second of loading time can reduce your conversions by up to 7%. With our free Google speed test, you get detailed insights into your website's performance – based on real Google PageSpeed Insights data.

Analyze your site now for mobile and desktop and receive actionable recommendations to improve your Core Web Vitals.
