Core Web Vitals in 2026: what actually matters

LCP, INP and CLS explained without jargon, with the fixes we apply on every project.

Why speed sells

Every extra tenth of a second of loading reduces conversions. It's not an opinion: it's what we see in our clients' data.

Google uses Core Web Vitals as a ranking signal, but the real reason to care is simpler: people hate waiting.

LCP: the main content

Largest Contentful Paint measures when the biggest element appears. Our target is under 2 seconds on mobile.

The golden rule: the main heading must be real HTML, not an image or JavaScript-generated text.

INP: responsiveness

Interaction to Next Paint measures how quickly the site responds to clicks. Splitting long tasks and loading JavaScript only when needed makes the difference.
