Website Speed Test
& SEO Analyzer
Check how a public page loads on mobile and desktop. This free analyzer uses Google PageSpeed Insights to show Lighthouse performance, accessibility and SEO checks, with loading metrics you can review before planning changes.
Enter the page you want to test
This sends your entered public URL to Google PageSpeed Insights through our analysis service. Fresh mobile and desktop tests may take a little time. Results are Lighthouse lab data.
How to use this tool
Choose a public URL
Test the actual page you want to improve. A product page or service page can behave differently from your homepage.
Run the analysis
The tool requests fresh mobile and desktop tests. Keep the page open while the service returns its results.
Review the slower parts
Compare the device results and look at the metrics and returned opportunities. Recheck the same URL after making a change.
What should you look at first?
When content appears
First Contentful Paint describes when content first appears. Largest Contentful Paint tracks the largest visible content element. Review these alongside what you see when you load the page.
Movement and delays
Cumulative Layout Shift records unexpected movement during the test. Total Blocking Time helps identify work on the main thread that can delay interaction.
Returned opportunities
Lighthouse may return suggestions for further investigation. Check that a suggestion applies to your page before asking a developer to implement it.
| If you find this | Next step |
|---|---|
| Mobile and desktop scores differ | Compare the test conditions and the metrics for each device. One result does not explain the other. |
| A metric worsens between tests | Repeat the test and check for changes to images, scripts, templates or hosting conditions. |
| No opportunities are returned | Review the available metrics and the live page. An empty suggestions list is not a complete website assessment. |
These results are Lighthouse lab tests. This tool does not provide a real-user Core Web Vitals assessment or an INP result. A high automated SEO score also does not establish whether a page answers the right searches.
Your questions, answered
Is this website speed test free?
Yes. Enter a public page URL to request the mobile and desktop checks described here. The live analysis depends on Google PageSpeed Insights being available.
Why can the scores change?
A fresh test can encounter different server responses or loading conditions. Compare several runs and record website changes before deciding that one edit caused the difference.
Are these real-user Core Web Vitals results?
No. The page shows Lighthouse lab metrics. Use real-user evidence separately when reviewing how visitors experience your website.
Does a high SEO score mean the page will rank?
The score covers automated checks in Lighthouse. Search performance also depends on the content, page purpose, competition and other factors beyond this test.
What if the analysis cannot run?
Confirm that the page is public and the URL includes https://. If the service is unavailable, try again later or use Google PageSpeed Insights directly.
Can you help with the findings?
Yes. Share the page URL and the results you received with our technical SEO team so we can discuss the issue and the work needed.
Need help with a slow page?
Send us the URL and the metrics that concern you. We can help investigate the cause and agree which changes need attention.
