Web Page Test —
Check Your PageSpeed Insights With Our Free Tool

Yes — 100% free, forever, with zero registration, no account, no email, and no credit card. Enter any URL, press Analyse, and receive full Google PageSpeed Insights results immediately. You can test unlimited URLs during a session — no sign-up required for any test. The tool uses Google's publicly accessible PageSpeed Insights API endpoint and returns the same data as Google's own tool at pagespeed.web.dev.

Our free online web page test uses the exact same Google PageSpeed Insights API as pagespeed.web.dev — so the scores and data are identical. The difference is the interface: we display the results with a cleaner visual layout, colour-coded Core Web Vitals with explicit pass/fail indicators, and an annotated opportunities list that makes it easier to understand what to fix and why. The underlying data source is Google's API, so scores are never different from what you would see on Google's own tool.

PageSpeed scores naturally vary by 5–10 points between runs due to: network variability (Google runs the test from its servers, which experience real-world latency fluctuations), server load variance (your server's response time varies under different load conditions), third-party scripts (analytics, chat widgets, ad scripts load at different speeds), and CPU throttling simulation variance on mobile tests. This is expected and documented by Google. Run 3 tests and average the scores for a reliable baseline — our free online tool makes this fast and easy with no registration required.

Mobile testing simulates a Moto G4 smartphone with 4× CPU slowdown, 150ms round-trip latency, and 1.6 Mbps download speed — reflecting a mid-range Android device on a slow 4G connection. This represents a significant portion of real global web traffic. Desktop testing simulates a fast desktop computer with no CPU throttling and a fast broadband connection. Mobile scores are almost always lower — often 20–40 points below desktop — and this is normal. Google's SEO ranking signals use the mobile version, making mobile the more important score to optimise for search performance.

The PageSpeed score number itself (0–100) is not a direct ranking factor. What matters are the Core Web Vitals — LCP, INP (formerly FID), and CLS — which ARE confirmed Google ranking signals since June 2021's Page Experience Update. A page that fails Core Web Vitals (LCP >4s, CLS >0.25, INP >500ms) may rank lower than a competitor page with similar content but better Core Web Vitals in the same search result. A PageSpeed Performance score below 50 typically correlates strongly with Core Web Vital failures. Use our free online test to check your Core Web Vital pass/fail status directly.

Field data (from the Chrome UX Report) only appears for URLs that have been visited by a sufficient number of Chrome users in the past 28 days. Google requires a minimum threshold of visits to anonymise and report field data. New pages, low-traffic pages, or pages behind logins will show "no field data" — this is normal. The lab data (Lighthouse simulation) is always available regardless of traffic levels. The lab metrics from our free online test are still fully valid for identifying performance issues even without field data.

Yes — you can test any publicly accessible URL with our free online web page test, including competitor websites. This is a legitimate and common SEO practice — understanding how your competitors' pages perform helps set realistic improvement targets and identify technical advantages to pursue. Our tool simply queries Google's public API with the URL you provide — the same test Google runs on all pages it crawls. No registration or permission is needed to test any public URL.

The Opportunities section lists specific, actionable improvements Lighthouse has identified on your page that could improve load time — each with an estimated time saving in milliseconds. Common opportunities include: Serve images in next-gen formats (convert to WebP/AVIF), Eliminate render-blocking resources (defer CSS/JS), Properly size images (resize to display dimensions), Remove unused JavaScript (code splitting), Enable text compression (Gzip/Brotli), and Reduce initial server response time (TTFB). Prioritise opportunities with the highest estimated time savings first for maximum PageSpeed score improvement.

Our free online web page test uses Google's public PageSpeed Insights API without an authentication key, which is rate-limited to approximately 25 requests per 100 seconds per IP address. If you test many URLs quickly, you may hit this limit and receive an error. The solution is simply to wait 30–60 seconds before running the next test. For high-volume testing (dozens of URLs), you can get a free Google API key from console.cloud.google.com — the PageSpeed Insights API provides 25,000 free requests per day with an API key.

Google's colour thresholds define the targets: 90–100 (Green / Good) is excellent and means your page is passing all Core Web Vitals — this is the target for competitive SEO. 50–89 (Orange / Needs Improvement) means some Core Web Vitals may be marginal — improvement recommended but not critical. 0–49 (Red / Poor) strongly suggests Core Web Vital failures — immediate optimisation recommended as rankings may be affected. For most websites, achieving 75+ on mobile is a realistic and meaningful target that ensures Core Web Vital passage. Run the free online test on your key landing pages first — those driving the most organic traffic — and optimise them first for maximum SEO impact.
