Full definition
Core Web Vitals are three Google metrics: LCP (load speed), FID/INP (interactivity), and CLS (visual stability). They're an important SEO ranking factor — Google favors sites that are fast and stable.
📌
Why it matters
These measure experience as real users actually encounter it. They will not lift an average site to the top, but they can hold a slow one back.
🧮 A worked example
A page whose main content appears after four seconds loses a significant share of visitors before they have seen anything — especially on mobile.
⚠️ The common mistake
Chasing a perfect score in a testing tool. What counts is what real users experience in the field, not a single lab run.
