More than half of all web traffic now comes from phones, and Google predominantly uses the mobile version of pages for indexing and ranking. A site that looks fine on a desktop monitor can be unreadable on a small screen — tiny text, sideways scrolling, buttons too close together. Our Mobile Friendly Test analyzes any URL for the technical signals of mobile readiness and scores it out of 100.
The test checks four things that matter most: whether the page sets a proper viewport meta tag, whether its CSS includes responsive breakpoints, whether any elements use large fixed widths that force horizontal scrolling, and whether text is set at readable sizes. Each check is reported individually with a pass or fail, so you know exactly what to fix rather than getting a vague thumbs-down.
It is a quick first audit, not a replacement for testing on real devices — but it catches the most common and most damaging mobile issues in seconds. Bloggers use it before launching a redesign, SEOs use it when auditing client sites, and anyone can use it to check a competitor. Free, instant, no signup.

FAQs
My score is 70 — is that bad?
It means “needs improvement.” The most impactful fix is usually the viewport meta tag; without it, mobile browsers render the desktop layout shrunk down. Fix the failed checks one by one and re-test.
Does this test check tap targets and touch usability?
It focuses on structural signals — viewport, responsive CSS, fixed widths and font sizes. For tap-target spacing and real-device behavior, test on an actual phone as well.
Will a low score hurt my Google rankings?
Google uses mobile-friendliness as a ranking signal for mobile searches, and a poor mobile experience increases bounce rates. It is worth fixing for both SEO and your visitors.
