Site speed and Core Web Vitals: how to speed up

Site speed is not just visitor comfort. Since 2021, „Core Web Vitals“ metrics are an official Google ranking factor. A slow site loses both positions and customers.

What are Core Web Vitals

• LCP (Largest Contentful Paint) – how fast the main content loads. Target: under 2.5s.
• INP (Interaction to Next Paint) – how fast the site responds to clicks. Target: under 200 ms.
• CLS (Cumulative Layout Shift) – whether elements „jump“ while loading. Target: under 0.1.

Why speed matters

Studies show that if a page takes longer than 3 seconds to load, some visitors leave. A faster site means better rankings, a lower bounce rate and higher conversion.

Every second counts: improving speed often raises both positions and sales at the same time.

How to speed up your site

• Optimize images – compress and use the WebP format.
• Enable caching and a content delivery network (CDN).
• Reduce code – minify CSS and JS, remove unnecessary scripts.
• Use lazy loading – images load only when they appear on screen.
• Good hosting – a cheap server is often the cause of slowness.
