What this tool checks

This tool evaluates your site's mobile experience across multiple dimensions. It checks for a properly configured viewport meta tag, adequate tap target sizes, readable font sizes without zooming, responsive images, content width fitting the screen, web app manifest presence, and touch icon configuration. It also pulls mobile-specific scores from Google's Lighthouse engine.

Why it matters

Over 60% of web traffic comes from mobile devices, and Google uses mobile-first indexing. If your site doesn't work well on phones, you're losing both visitors and search rankings. Small tap targets frustrate users, tiny fonts drive them away, and content that overflows the screen makes your site look broken. Every second of friction costs conversions.

Common issues we find

  • Missing or incorrectly configured viewport meta tag
  • Tap targets too small or too close together (under 48px)
  • Text too small to read without zooming (under 16px base font)
  • Content wider than the viewport, causing horizontal scrolling
  • No web app manifest or touch icons for home screen installs
