Page Speed Analyser
Measure your website's loading performance using Google's Lighthouse. Get actionable insights to improve Core Web Vitals and user experience.
What is the Page Speed Analyser?
Measure how fast your website loads using real Google Lighthouse data. This page speed analyzer doubles as a full website speed test — enter any URL and get performance scores, Core Web Vitals metrics, and a prioritised list of fixes to make your site faster. Page speed directly impacts user experience, bounce rates, and search engine rankings, so knowing exactly where you stand is the first step to a faster, higher-ranking site. Use it as a free internet speed analyzer to analyze website load time from a real visitor perspective: it measures total load time, Time to First Byte (TTFB), page load time and Core Web Vitals, then shows you how to improve website load speed.
Example: diagnosing why a blog loads in 6.2 seconds
Say you run your blog’s homepage through the analyser. It returns a Performance score of 38 with LCP at 6.2 s — well above the 2.5 s threshold. The top opportunity flags three unoptimised hero images totalling 4.8 MB. After converting them to WebP and lazy-loading below-the-fold shots, a re-test shows LCP drops to 1.9 s and the score jumps to 87.

Key Features
Google Lighthouse Integration
Powered by the official PageSpeed Insights API, delivering the same data Google uses to assess your site's performance — not a rough estimate.
Core Web Vitals
See your Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Total Blocking Time (TBT) scores — the metrics Google uses for ranking.
Mobile & Desktop Testing
Run the website speed test for both mobile and desktop to understand performance across different devices and connection speeds.
Full Lab Metrics
Get First Contentful Paint, Speed Index, and Time to Interactive alongside the headline score, so you can see precisely where the delays happen.
Prioritised Opportunities
A ranked list of opportunities and diagnostics tells you exactly what to fix first, from oversized images to render-blocking scripts.
Four Score Categories
Beyond performance, you also see Accessibility, Best Practices, and SEO scores for a complete health check in one test.
How to Use This Tool
Enter your URL
Paste any webpage URL — your own site, a competitor's, or any page you want to benchmark with the speed test.
Choose device type
Select Mobile or Desktop. Mobile usually scores lower because it simulates a slower CPU and network, and it reflects how most visitors experience your site.
Run the analysis
Click Analyse and the page speed analyzer runs a full Lighthouse audit, typically completing in 15–30 seconds.
Review your scores and metrics
Examine the Performance, Accessibility, Best Practices, and SEO scores along with your Core Web Vitals and lab metrics.
Fix the top opportunities
Work through the prioritised opportunities — compress images, defer scripts, enable caching — then re-run the test to confirm your gains.
Why This Matters for SEO
Google has confirmed that page speed is a ranking factor, and Core Web Vitals — LCP, CLS, and INP — are part of its ranking algorithm. Sites that load in under 2.5 seconds see significantly lower bounce rates and higher conversions, while every extra second of load time costs you visitors and sales. Running a regular website speed test and acting on the results is one of the highest-impact things you can do for both SEO and revenue. Unlike basic checkers, this analyser uses Google's own Lighthouse engine, so the scores you see are the same ones that influence your rankings.
