Mobile Friendly Test

Free Mobile Friendly Test — Google Mobile Usability Check

Google's mobile-first indexing means the mobile version of your website is what Google primarily uses to determine your rankings. A site that fails mobile usability tests ranks lower and provides a poor experience to the majority of today's web users, over 60% of whom browse on mobile devices. This free Mobile Friendly Test checks any URL using Google's PageSpeed Insights API and returns real Lighthouse mobile scores and specific usability issues to fix.

Enter any URL to run a full mobile performance audit. The tool returns the mobile performance score, Core Web Vitals on mobile, specific usability failures (text too small, clickable elements too close together, viewport not configured), and opportunities for improvement.

Mobile scores are typically lower than desktop scores because of smaller screens, slower network connections, and less powerful CPUs on mobile devices. Prioritize mobile performance issues — they directly affect the majority of your visitors.

Common Mobile Usability Issues

Viewport not configured. The meta viewport tag is missing or incorrect. Without it, mobile browsers render the page at desktop width and scale it down, making text tiny. Fix: add <meta name="viewport" content="width=device-width, initial-scale=1">.

Text too small to read. Font size below 16px is difficult to read on mobile without zooming. Use a minimum base font size of 16px for body text.

Clickable elements too close together. Buttons and links must be at least 48x48px with adequate spacing. Tiny tap targets cause accidental taps and frustrate users.

Content wider than screen. Horizontal scrolling indicates content or elements are wider than the viewport. Use relative width units (%, vw) instead of fixed pixel widths.

Slow mobile load time. Mobile connections are slower than desktop broadband. Heavy pages, uncompressed images, and render-blocking resources cause especially poor mobile performance.
