Mobile-friendly test
Check whether a page works on a phone: whether it is set up for phone screens, how quickly its main content appears on a mobile connection, whether it jumps around while loading, and how much it makes a phone download. Google retired its own Mobile-Friendly Test in December 2023; this checks the same underlying conditions.
The rest of your site, checked for €79
The Website Health Report includes the viewport and page weight findings and the mobile speed score, and adds the SSL certificate and security headers, email authentication, broken links and form destinations across up to fifty pages, domain expiry and search checks. Every finding comes with the evidence and a fix list in priority order. One payment of €79.
What the test checks
- Viewport: the tag that tells a phone to lay the page out at the width of its screen, and whether it stops visitors zooming in.
- Largest Contentful Paint: when the biggest thing on screen finishes appearing on a simulated phone connection. Google rates up to 2.5 seconds good and over 4 seconds poor.
- Cumulative Layout Shift: how much the page moves while it loads. Google rates up to 0.1 good and over 0.25 poor.
- Page weight: how much a phone downloads to show the page, how many requests that takes, and the heaviest files.
Google retired its Mobile-Friendly Test and the Search Console Mobile Usability report in December 2023, as announced on the Google Search Central blog. The timing figures here come from Google’s PageSpeed Insights, which runs Lighthouse, the tool Google pointed to instead.
This is a lab test from one location on a simulated connection, not a record of what your visitors experience. Run it twice before acting on a borderline result. For more on speed, read why a website can be slow or run the website speed test.
Mobile-friendly tests, answered
What happened to Google’s Mobile-Friendly Test?
Google retired it, along with the Mobile Usability report in Search Console, in December 2023, and pointed people to Lighthouse instead. Google said at the time that mobile usability still matters. This tool checks the same underlying conditions: whether the page is set up for phone screens, how quickly its main content appears on a phone, whether it jumps around while loading, and how much it downloads.
Does this check whether text is readable without zooming?
Only when Google’s speed service still reports it. That check came from a Lighthouse audit called font-size, which Lighthouse removed in version 13. When the audit is not in the response, we leave the row out rather than guess. The viewport row still tells you whether zooming is allowed.
Why does the result sometimes say Google’s service was unavailable?
The timing figures come from Google’s PageSpeed Insights, which limits how often it can be asked. When it is busy, we still check the viewport and measure the page weight ourselves, and say plainly that the timing figures were not available this time. Try again in a few minutes.
Is this the same check the paid report runs?
The same code. In the €79 Website Health Report, the viewport and page weight are findings in the Speed section, and the timing figures sit in the mobile speed finding. The report adds the SSL certificate and security headers, email authentication, broken links and forms, domain expiry and search checks.
