Enter your website address to see how fast it loads on mobile and desktop. You get your PageSpeed score, your Core Web Vitals, real-user data when Google has it, and a short list of what to fix first. It is free and needs no sign-up.
Google rates each Core Web Vital as good, needs improvement or poor. To pass, aim for the good range on all three, measured on real visitors at the 75th percentile.
| Metric | Good | Needs improvement | Poor |
|---|---|---|---|
| Largest Contentful Paint (LCP) | 2.5 s or less | 2.5 to 4 s | Over 4 s |
| Interaction to Next Paint (INP) | 200 ms or less | 200 to 500 ms | Over 500 ms |
| Cumulative Layout Shift (CLS) | 0.1 or less | 0.1 to 0.25 | Over 0.25 |
| Overall performance score | 90 to 100 | 50 to 89 | 0 to 49 |
Slow pages lose visitors before they read a word, especially on mobile data. For a business website that means fewer enquiries from the same traffic. Speed is also part of Google's page experience signals, and a site that loads quickly is cheaper to run and easier for search engines to crawl.
We run Google's PageSpeed Insights, which loads your page in Lighthouse on Google's servers, scores it from 0 to 100 and reports real-user Core Web Vitals when your site has enough Chrome traffic. We then show the results in plain language and list the biggest fixes first.
A performance score of 90 to 100 is good, 50 to 89 needs improvement and below 50 is poor. Scores for mobile are usually lower than desktop because the test simulates a mid-range phone on a slower connection.
Core Web Vitals are three measurements Google uses to judge page experience: Largest Contentful Paint (how fast the main content appears), Interaction to Next Paint (how quickly the page responds to taps and clicks) and Cumulative Layout Shift (how much the page jumps around while loading).
Yes, but it is one signal among many. Google uses page experience, including Core Web Vitals, as part of ranking. A fast site rarely outranks a much more relevant one, but speed matters most when pages are otherwise close, and it strongly affects how many visitors stay and enquire.
Lab tests simulate loading under controlled conditions, and small differences in server response, third-party scripts and network timing change the result. Test two or three times and look at the pattern. The real-user data, when shown, is more stable.
The mobile test slows the network and CPU to resemble a typical phone, so heavy images and JavaScript hurt more. Google indexes the mobile version of your site first, so the mobile score is the one to focus on.
Yes. We build fast Next.js websites and speed up slow ones. Send us your result through the buttons under your report and we will tell you what is slowing the site and what it would take to fix.
