Website Speed Test
Enter a URL to test page load time, analyse performance, and find what's slowing it down.
A slow website costs you visitors, rankings, and conversions. Google uses Core Web Vitals as a ranking signal. Your users make up their mind in under three seconds. This tool runs the same tests Google runs and tells you exactly where the time is going.
Results come from Google PageSpeed Insights, which runs your URL through a real Lighthouse audit. You get a performance score from 0 to 100, your Core Web Vitals, total page weight, number of requests, and a list of specific things slowing the page down, sorted by how much time each one is costing.
What the performance score means
The score is a weighted composite of six timing metrics, not a simple average. Largest Contentful Paint and Total Blocking Time carry the most weight. A score of 90 or above is good. 50 to 89 needs work. Below 50 is poor and likely affecting your search rankings and bounce rate.
The metrics, briefly
LCP (Largest Contentful Paint) is when the biggest visible element finishes loading, usually your hero image or main heading. Aim for under 2.5 seconds. FCP (First Contentful Paint) is when the first bit of content appears. TBT (Total Blocking Time) measures how long the main thread is blocked and unable to respond to input. CLS (Cumulative Layout Shift) measures visual instability, like buttons jumping around as the page loads. TTI is when the page becomes fully interactive.
Desktop vs mobile
Google primarily uses mobile performance for ranking (mobile-first indexing), so mobile scores tend to matter more for SEO. Desktop scores tend to be significantly higher since the simulated connection speed is faster. If your mobile score is well below your desktop score, that gap is worth closing first.
Questions
Why does my score vary between tests?
PageSpeed Insights runs a simulated test from Google's servers, so network conditions and server response times can shift results slightly between runs. For a fair read, test two or three times and take the middle result.
What's a good score?
90 or above is considered good. 50–89 needs improvement. Below 50 is poor. Anything under 50 on mobile is likely costing you SEO visibility and conversions.
My score is fine but my site feels slow. Why?
Lighthouse tests from a specific simulated device and connection. If your actual users are on slower connections, older devices, or different locations, their experience can be worse than the score suggests. Run a real-device test too.
What's the fastest way to improve a low score?
Fix the bottlenecks shown at the bottom of your results first, sorted by potential time savings. Commonly: compress and lazy-load images, defer unused JavaScript, enable text compression, and use a CDN.
Waiting for results? Might as well.
