Mobile-friendly test
Check whether your site meets mobile usability standards. Tests the viewport meta tag, font sizes, tap target spacing and content width — all inside your browser.
Runs entirely in your browser. This tool analyses the current page metadata and does not make external requests.
Enter a URL and press Test mobile friendliness to check viewport, fonts, tap targets and content width.
Over 60% of web traffic comes from mobile devices. If your site is not mobile-friendly, you are losing visitors and rankings. Google uses mobile-first indexing, so your mobile experience is what determines your search position.
What this tool checks
The mobile-friendly test analyses four core areas: the viewport meta tag (essential for responsive behaviour), font sizes (should be at least 16px for readability), tap target spacing (links and buttons need enough space between them), and content width (should not overflow the screen). Each check returns a clear pass or fail result, and an overall score tells you how mobile-ready your site is.
If you are testing a page that is not your own, the tool checks the meta tags and structure of the current page. For a full mobile usability audit including page speed on mobile, Core Web Vitals and real device testing, we recommend Google's Mobile-Friendly Test tool alongside this one.
How to fix common mobile issues
Most mobile problems come from a missing or incorrect viewport tag, fixed-width layouts, or elements designed for desktop that do not scale. Add <meta name="viewport" content="width=device-width, initial-scale=1"> to every page, use relative units like percentages and ems instead of pixels, and test on real devices. Our team builds all sites mobile-first, so they work perfectly on every screen size.
Frequently asked questions
A mobile-friendly site has a responsive design, proper viewport meta tag, readable font sizes, adequate tap targets, and content that fits the screen without horizontal scrolling.
Google uses mobile-first indexing, meaning it primarily evaluates your site based on its mobile version. A site that is not mobile-friendly will rank lower in search results regardless of its desktop experience.
This tool works by analysing the page you are currently viewing. It checks the meta tags and structure of whatever page you point it to, as long as you enter the URL and the page loads in your browser context.
