How Core Web Vitals Affect SEO in 2025

Core Web Vitals are Google's way of measuring real user experience. They have a direct impact on search rankings, especially on mobile devices.

What are Core Web Vitals?

• LCP (Largest Contentful Paint) – how fast the main content loads.
• INP (Interaction to Next Paint) – how fast the page reacts to user input.
• CLS (Cumulative Layout Shift) – how stable the layout is during loading.

Why they matter for SEO

Pages with very poor Core Web Vitals can lose positions even if their content is strong. Google prefers sites that are both useful and pleasant to use, so speed and stability are no longer optional.

How to measure Core Web Vitals

• Google PageSpeed Insights,
• Search Console (Core Web Vitals report),
• third‑party scanners like Skyphaze.

Skyphaze shows the most important metrics directly in a single report, along with performance and security information.

Quick ways to improve Core Web Vitals

• Compress and resize images,
• remove unused JavaScript and CSS,
• use a fast hosting provider or CDN,
• reserve space for images, banners and embeds to avoid layout shifts.

Improving Core Web Vitals helps both your SEO rankings and your conversion rates.
