What this page speed test measures
- Largest Contentful Paint (LCP) — main content render time. Good: under 2.5 s.
- Interaction to Next Paint (INP) — responsiveness to clicks and taps. Good: under 200 ms.
- Cumulative Layout Shift (CLS) — visual stability. Good: under 0.1.
- Total Blocking Time (TBT) — main-thread blocking. Good: under 200 ms in lab conditions.
- Speed Index — how quickly content is visually populated. Good: under 3.4 s on mobile.
- Time to Interactive (TTI) — when the page becomes reliably usable. Good: under 3.8 s.
How to read your score: a decision guide
- Score 90–100: keep monitoring monthly; spend effort on content and conversion instead.
- Score 50–89: fix the top 3 opportunities above — usually images, render-blocking CSS/JS, and unused JavaScript.
- Score 0–49: treat it as a platform problem: audit your hosting TTFB, theme/page-builder bloat, and third-party tags.
- Lab good, field poor: your real users are on slower devices or networks — prioritise mobile and cache/CDN work.

Frequently asked questions
Is this website page speed test free?
Yes. The tool is 100% free with no signup, no credit card, and no usage limits per visitor. It runs a real Google Lighthouse test through the PageSpeed Insights API.
What is a good page speed score in 2026?
A Lighthouse performance score of 90-100 is good, 50-89 needs improvement, and 0-49 is poor. For Core Web Vitals, aim for LCP under 2.5 s, INP under 200 ms, and CLS under 0.1.
What is the difference between lab data and field data?
Lab data comes from a single simulated Lighthouse run on a throttled mobile connection. Field data comes from the Chrome User Experience Report (CrUX) — real Chrome users over the trailing 28 days. Google uses field data for the page experience ranking signal.
Does page speed affect Google rankings?
Yes. Core Web Vitals are a confirmed Google ranking signal as part of page experience. Speed also affects conversion: Deloitte found a 0.1 s improvement in mobile load time lifted retail conversions by 8.4%.
