Mobile-Friendly Test
Viewport, tap-target, font-size and content-width checks from Lighthouse on a mobile device, plus a mobile score.
Why it matters
Google indexes the mobile version of your site. Tiny text, cramped buttons and content wider than the screen cost rankings and calls.
What you get
Lighthouse's mobile checks - viewport, font size, tap targets, content width, layout shift - with a mobile performance score and a screenshot of how the page rendered on a phone.
