Core Web Vitals measure what users actually experience: how fast content appears, how responsive the site feels, how stable the layout is. For B2B, where buyers research before they buy, these metrics directly affect both rankings and conversion.
The Three Metrics
LCP (Largest Contentful Paint) — How long until the main content is visible. Target: under 2.5 seconds. Slow LCP means users leave before they read.
INP (Interaction to Next Paint) — How quickly the site responds to clicks and taps. Target: under 200ms. Laggy forms and buttons kill trust.
CLS (Cumulative Layout Shift) — How much content jumps around while loading. Target: under 0.1. Layout shifts frustrate users and hurt conversions.
Why B2B Sites Struggle
- Heavy CMS platforms with bloated themes
- Unoptimized images and third-party scripts
- Complex forms and interactive elements
- Legacy architecture never built for speed
The Fix
- Audit first — Lighthouse, PageSpeed Insights, or a real-user monitoring tool.
- Prioritize — Fix LCP (images, fonts, server) before micro-optimizations.
- Measure — Track Core Web Vitals in production, not just in lab tests.
