This check proves what one Lighthouse run scored on one simulated device and network, together with the lab Core Web Vitals from that run and the top opportunities it identified. Lab results vary between runs by design, and a lab score is not the field experience real users have, which is what Core Web Vitals measures.
A live Lighthouse lab audit. The result identifies where its evidence came from.
Scores come from a single Lighthouse lab audit in a simulated environment. Lab results are a diagnostic and can differ from real-user field data.

Audyt Lighthouse uruchamia stronę w kontrolowanym laboratorium i ocenia cztery kategorie od 0 do 100. To najszybszy sposób, aby znaleźć, co spowalnia stronę i uzyskać konkretne możliwości - ale Google ocenia na podstawie danych z rzeczywistych użytkowników, więc traktuj wynik laboratoryjny jako listę rzeczy do zrobienia, a nie werdykt.
Dane laboratoryjne są powtarzalne i świetne do debugowania. Dane z terenu (podstawowe wskaźniki internetowe) odzwierciedlają rzeczywistych użytkowników na rzeczywistych urządzeniach i sieciach. Użyj obu: napraw w laboratorium, potwierdź w terenie.
Submit the page address you want audited. A page behind a login, a paywall or a geographic block cannot be audited because the analyser reaches it as an anonymous visitor. Treating a single run's score as a stable number is the misreading to avoid; run it twice before you act on a difference.

The category scores and the lab Core Web Vitals from that run are reported as returned, and the top opportunities Lighthouse identifies are surfaced using its published scoring methodology rather than a re-weighting of ours.
Google's Lighthouse documentation defines the audits, the weightings and the scoring curve, and the PageSpeed Insights documentation defines how a lab run is produced and how it differs from field data. Both are reported as published, so a score here can be reproduced against Google's own tool rather than only against ours.

Lighthouse scores run from 0 to 100. Broadly, 90 and above is good, 50 to 89 needs improvement, and below 50 is poor. Treat it as lab guidance, not a real-user guarantee.
Lighthouse runs one audit under simulated network and device conditions, so it may not match real visitors' varied hardware and connections. Lab data is reproducible and diagnostic; field data reflects actual user experience over time.
Work through the listed opportunities, commonly compressing and sizing images, deferring unused scripts, eliminating render-blocking resources, and enabling caching. Each opportunity estimates potential savings, so prioritise the ones with the largest estimated time reduction.
PageSpeed runs a Lighthouse lab audit with simulated conditions and diagnostic opportunities. The Core Web Vitals Checker reports real-user field data at the 75th percentile. Use lab to diagnose, field to judge actual experience.
They are LCP, INP-related and CLS measurements taken during the single simulated Lighthouse run. Because they come from one lab test, they can differ from the real-user 75th-percentile field values Google actually assesses.
Lighthouse simulates a run each time, so variability in network modelling, server response and page scripts shifts scores. Run several audits and look at the trend rather than treating one number as absolute.
No. Lighthouse checks automatable accessibility issues only and cannot verify everything, like meaningful alt text or keyboard flows. A high score is a helpful baseline, not proof of full accessibility compliance.
Faster, well-built pages improve user experience and support Google's page experience signals. The audit surfaces concrete speed and best-practice fixes, helping reduce abandonment and remove technical barriers that can hold back rankings.
No. It is one lab audit in a simulated environment representing a single test condition. To understand real visitors across devices and networks, pair it with real-user field data from the Core Web Vitals Checker.
