Mobile-friendly test

Google retired its Mobile-Friendly Test in December 2023, but mobile still matters more than ever: Google indexes the mobile version of your site. Check yours below.

Free, no sign-up. Checks one page in about 20 seconds. We fetch it like a search engine and don't keep your content.

What makes a page mobile friendly?

  • A viewport tag set to the device width, without blocking pinch-zoom.
  • Text that's readable without zooming, and buttons large enough to tap with a thumb.
  • No content wider than the screen, so nobody has to scroll sideways.
  • Fast loading on a mobile connection – see the real-world speed section of your report.
  • Tap-to-call or tap-to-email links so visitors can contact you instantly.

Why Google closed its test – and what to use instead

Google pointed site owners to Lighthouse and Search Console instead. XKey combines a mobile checklist with Lighthouse's mobile performance data from Google PageSpeed Insights, so you get both in one report. Your results open at the Mobile & accessibility section.

Frequently asked questions

Is mobile-first indexing still a thing?

Yes. Google uses the mobile version of your pages for indexing and ranking, so anything missing on mobile is effectively missing for Google.
