Is your site actually fast — on mobile, for real visitors?
Core Web Vitals are the speed and stability metrics Google uses as a ranking signal. We measure yours with the real PageSpeed Insights API — no estimates — and explain exactly what to fix.
No signup required to see your score.
The three metrics that matter
LCP — Loading
Largest Contentful Paint: how long until the main content of the page appears. Slower than 2.5s starts hurting both rankings and real users.
INP — Interactivity
Interaction to Next Paint: how fast the page responds to a click or tap. Heavy JavaScript is the usual culprit when this is slow.
CLS — Stability
Cumulative Layout Shift: how much content jumps around while loading. Images and ads without reserved space are the most common cause.
