Core Web Vitals Checker
अपनी report से measured LCP, INP और CLS assess करें. यह browser-local tool किसी website को fetch या measure नहीं करता.

तीन metrics, तीन अलग सवाल
Core Web Vitals test loading, responsiveness और visual stability examine करता है. Consistent device group के लिए 75th percentile field values compare करें. यह analyzer आपके supplied data पर thresholds apply करता है; report की authenticity या freshness verify नहीं करता.
अपनी exported assessment के साथ original report रखें. Lab run तुरंत change investigate करने में मदद कर सकता है, जबकि field data collection period में visitors को reflect करता है. Good result या performance score search ranking guarantee नहीं करता.
Loading
LCP: सबसे बड़ा visible content कब appear होता है.
Responsiveness
INP: observed interactions में delay.
Stability
CLS: page layout में unexpected movement.
Provenance
Device, scope और collection dates साथ रखें.
Read thresholds without losing context
LCP describes loading, INP describes interaction responsiveness, and CLS describes visual stability. Lower values are better. CLS is unitless.
| Metric | Good | Needs improvement | Poor |
|---|---|---|---|
| LCP | ≤ 2,500 ms | > 2,500–4,000 ms | > 4,000 ms |
| INP | ≤ 200 ms | > 200–500 ms | > 500 ms |
| CLS | ≤ 0.1 | > 0.1–0.25 | > 0.25 |

01 · Keep field and lab separate
PageSpeed Insights presents real-user field information and a separate simulated lab run. CrUX field reports aggregate observations over a 28-day collection window. A fresh lab result does not replace that history. Record the dates and device before comparing two assessments.
02 · Check the scope
A URL report concerns one page. An origin report aggregates pages under the same origin. This importer presents each separately and never fills missing URL metrics with origin values. PSI field JSON may omit device and collection dates; check the original report when they are unavailable here.
03 · Turn a finding into an investigation
For slow loading, inspect the LCP element and its resource waterfall. For delayed interactions, profile the work triggered by an actual interaction. For layout shifts, identify the moving elements and missing reserved space. The values alone cannot identify a root cause.
