Website Speed Test
See your site's instant speed audit in seconds, with Google PageSpeed scores added when available.
This tool works in two layers. The instant audit reads your page's HTML from our server and returns a result within a few seconds; it marks items such as server response time, compression, caching, blocking scripts, images and fonts as good, needs attention or poor, rather than handing out a single score. A Google PageSpeed measurement is added when it can be obtained; it can take twenty to forty seconds and brings four scores, performance, accessibility, best practices and SEO, along with LCP, INP and CLS figures.
According to web.dev's own thresholds, a good server response time (TTFB) is under 800 milliseconds, while anything over 1800 milliseconds is poor; a good LCP sits under 2.5 seconds, a good INP under 200 milliseconds, and a good CLS under 0.1. Once Google's scores arrive, an overall score of 90 or above counts as good, 50 to 89 as average, and below 50 as poor.
The result is a single measurement taken at that moment (lab data), and may not exactly mirror what real visitors experience (field data); server load, network conditions and a visitor's location can all shift the figures. When Google's measurement service is busy, the PageSpeed section may not appear at all; in that case you still see the instant audit, along with a link to open the report directly in PageSpeed Insights.
How to use it
- Enter your site's full address, starting with https://.
- Start the test; the instant audit result arrives within a few seconds.
- Review the good, needs attention and poor marks on server response, compression, caching, images and fonts.
- If Google PageSpeed scores were added, review the four scores and the LCP, INP and CLS figures.
- Prioritise and fix whatever is marked poor, then run the test again a few days later.
FAQ
Why do mobile and desktop scores differ?
Google's measurement simulates a mobile connection and processor, so the mobile score usually comes out lower than desktop. If most of your visitors arrive on mobile, that score deserves priority.
Does the score need to be perfect?
No. A Google score of 90 or above counts as good; what actually matters is keeping LCP, INP and CLS within their thresholds.
Why do Google scores sometimes not appear?
Google's measurement service can be busy, and the PageSpeed section may not arrive. When that happens you still get the instant audit result, plus a link to open the report directly in PageSpeed Insights.
Does this test store my data?
No sign-up is required and the address you enter isn't stored permanently. If you check the same address again soon, the result is kept in server memory for about ten minutes so it can respond quickly; for the Google measurement, the address is sent to Google's service.
