Technical Primer

The 3 Core Web Vitals That Rule Google Search

Google evaluates your website based on these three objective real-user metrics (CrUX data).

Metric 01 · Loading

Largest Contentful Paint (LCP)

Measures how quickly the largest visible element (hero headline or banner image) appears. Google requires LCP under 2.5 seconds. In WordPress, bloated themes push LCP to 4s–6s. Next.js delivers sub-0.8s LCP natively.

Metric 02 · Interactivity

Interaction to Next Paint (INP)

Replaced FID in 2024. Measures latency when a user clicks a button, menu, or form input. Google requires INP under 200ms. Heavy JavaScript plugins cause main-thread freezes that fail this audit.

Metric 03 · Visual Stability

Cumulative Layout Shift (CLS)

Measures unexpected layout shifts while a page loads (e.g. text jumping as an ad or un-sized image loads). Google requires CLS under 0.1. Next.js enforces automatic image sizing to guarantee a score of 0.00.
