Google ranks on field data from actual visitors, not a single Lighthouse run. Pulse checks both and tells you plainly whether a page passes the bar that actually matters.
2.5s
LCP threshold Google calls "good." Past 4s is "poor," and that's a ranking signal, not a suggestion.
200ms
INP threshold for responsiveness. Replaced FID in March 2024, most tools still quote the old metric.
0.1
CLS threshold for layout stability, measured on real page loads across a 28-day window.
