What Mobile-Friendly Test does
With most search traffic now coming from phones, a page that's hard to use on a small screen loses visitors regardless of how good its content is. This tool checks a URL against common mobile-usability factors and reports a score along with the specific issues found.
How to test a page
- Enter the full URL of the page you want to test.
- Select Run test.
- Review the mobile-friendliness score and the list of specific issues detected.
What's being checked
The check looks at mobile-usability signals visible in the page's own HTML and CSS: whether a proper viewport meta tag is set (and configured correctly), whether any CSS disables the browser's text-size adjustment, whether font sizes are set small enough to be hard to read on a phone, and whether a fixed-width element like a wide table would force horizontal scrolling on a narrow screen.
Why this matters for rankings, not just usability
Search engines evaluate pages primarily by how they perform on mobile, since that's how most visitors actually arrive — a page that scores poorly here isn't just harder to use, it's also likely at a disadvantage in mobile search results specifically. Fixing the flagged issues benefits both your visitors and your search visibility together.
