Free website health check
Enter any website address and get a plain-English report: speed on a phone and a desktop, what real visitors in Chrome experience, search basics, security headers and accessibility, each with a fix for the platform the site runs on. No sign-up, and nothing is stored.
Checking
- Loading the page on a simulated mid-range phone
- Timing how fast the main content appears
- Reading the search, security and accessibility basics
- Running the same test on a desktop
Usually 20 to 40 seconds. Google loads the page fresh each time.

The checklist
How the health check works
Your browser asks Google's PageSpeed Insights to load the page twice, on a simulated mid-range phone and on a desktop, and run Lighthouse, the same audit built into Chrome. We turn its results into plain-English findings: what passed, what is worth fixing, and how to fix it on the platform your site runs on.
Where enough people visit the site in Chrome, Google also returns what those real visitors experienced over the last 28 days. That is the data Google uses for its Core Web Vitals, so it counts for more than the lab test.
It checks the one page you enter, not your whole site, and speed figures vary a little between runs. For the full list of what to check by hand, see our website security checklist and technical SEO audit checklist.
Website health check: your questions answered
It loads your page twice, on a simulated mid-range phone and on a desktop, and reports speed (the Core Web Vitals and the biggest fixes, ranked by time saved), what the page is made of and which other companies' code it loads, security headers such as HSTS and Content-Security-Policy, search basics like the title, description and canonical tag, whether search engines may index the page, and accessibility basics such as text contrast, image descriptions and tap-target size. Where Google has enough Chrome visits, it also shows what real visitors experienced over the last 28 days.
No. Google retired its Mobile-Friendly Test on 1 December 2023. This check runs Google's Lighthouse through the PageSpeed Insights API, which looks at how your page loads and behaves on a phone, but it does not give Google's old pass or fail verdict.
Lighthouse loads your page fresh on each run, so network and server conditions change the speed figures a little. Look at the findings rather than a single score, and run it again if a result looks out of character.
No. The check runs in your browser and sends the address to Google's PageSpeed Insights service, which loads the page. Nothing is saved on our side.
Some, not all. Titles, descriptions and image sizes can be changed on any platform. Security headers and server speed often cannot be changed on a hosted website builder, because the platform controls them. Where a fix needs a developer or a different platform, the result says so.
