Real-user field data from the Chrome User Experience report. The result identifies where its evidence came from.
Check real-user Core Web Vitals (LCP, INP, CLS) from Chrome field data. Verify whether your site passes Google's Page Experience ranking assessment.

This check proves what real Chrome users experienced on this address over the trailing collection window, at the 75th percentile, for LCP, INP and CLS. It is field data, not a lab test, so it cannot be produced on demand: a URL with too little traffic has no URL-level record and falls back to origin-level, which is labelled.

This reads real-user field data collected over the trailing 28 days for pages with enough Chrome traffic. Low-traffic pages fall back to origin-level data or report no field data - this is not a lab test.

Core Web Vitals mesurent le chargement (LCP), l'interactivité (INP) et la stabilité visuelle (CLS) à partir de vrais utilisateurs Chrome - pas une simulation de laboratoire. Google utilise ces données de terrain comme signal de classement, donc la valeur p75 est ce qui compte, pas un score de laboratoire unique.
Les URL à faible trafic peuvent ne pas avoir leurs propres données de champ. Dans ce cas, cet outil revient aux données d'origine (site entier), qui sont clairement étiquetées - elles reflètent le site dans son ensemble, pas cette seule page.
Submit the page address you care about. If the report falls back to origin level, the numbers describe the whole site rather than that page, and the scope label says so. Reading an origin-level figure as a page result is the misreading this section prevents, and a brand-new page will have no data at all.
yourdomain.comToute forme d'adresse fonctionne - une URL avec un vrai trafic a les données de champ les plus riches. http ou https, avec ou sans www, un domaine nu ou un chemin complet - nous le normalisons pour vous.https://www.yourdomain.com/L'origine ou une page populaire est idéale ; nous revenons au niveau d'origine si une URL n'a pas d'échantillon.Reading 'no field data' as an errorUne page toute nouvelle ou à faible trafic n'a tout simplement pas d'échantillon du rapport UX Chrome, donc nous le disons honnêtement au lieu de deviner.The address is normalised and 75th-percentile real-user field data is read from the Chrome UX Report. LCP, INP and CLS are reported against the official Core Web Vitals thresholds, unchanged. Where URL-level data is unavailable the report falls back to origin level, and the scope the numbers came from is stated on the result.
Google's Core Web Vitals definitions supply the metrics and their thresholds, the Chrome UX Report supplies the field dataset and its 75th-percentile methodology, and Google's page-experience documentation defines how the signals are used in ranking. Thresholds are applied exactly as published, because a metric graded against a house bar is no longer that metric.

Lisez la spécificationIt reports real-user LCP, INP and CLS at the 75th percentile from Chrome field data over the trailing 28 days, and whether the page passes Google's Core Web Vitals assessment.
A page is considered good when LCP is 2.5 seconds or less, INP is 200 milliseconds or less, and CLS is 0.10 or less, all measured at the 75th percentile of real users.
LCP, Largest Contentful Paint, measures loading speed. INP, Interaction to Next Paint, measures responsiveness to input. CLS, Cumulative Layout Shift, measures visual stability. Together they reflect real perceived page experience for users.
Field data needs enough real Chrome traffic. Low-traffic pages fall back to origin-level data or report none at all. No data means insufficient samples, not that the page performs badly.
It means 75 percent of real page visits were at least this fast or stable. Google uses the 75th percentile so the assessment reflects most users, not just the fastest or an average, experience.
Field data is measured from real users' devices and networks over time, as this checker reports. Lab data comes from a single controlled test. Field data reflects genuine experience; lab data is reproducible but simulated.
Serve the main image or text quickly by optimising and preloading the largest element, reducing server response time, trimming render-blocking resources, and using efficient caching so LCP falls to 2.5 seconds or less.
No. Core Web Vitals are part of Google's page experience signals and help, but relevance and content quality matter more. Passing removes a disadvantage rather than guaranteeing a ranking boost on its own.
INP measures the latency of real user interactions across the whole visit, not just the first. A good INP of 200 milliseconds or less means the page reliably responds quickly whenever users tap or click.
No. It reports real-user field data at the 75th percentile from Chrome over 28 days. For a controlled lab audit with reproducible opportunities, use a Lighthouse-based tool like the PageSpeed Checker instead.
