About Mobile-Friendly Test
Test how mobile-friendly your website is. Check viewport configuration, touch targets, font sizes, and responsive design implementation.
Frequently Asked Questions
Is mobile-friendliness a Google ranking factor?
Yes. Google uses mobile-first indexing for all sites since 2023, meaning the mobile version of your page is what Google indexes and ranks. Pages that aren't mobile-friendly rank significantly lower in mobile search results.
What makes a website mobile-friendly?
Responsive design that adapts to screen sizes, properly sized tap targets (48×48px minimum), readable font sizes (16px+ base), no horizontal scrolling, fast loading on mobile networks, and a viewport meta tag with width=device-width.
What Core Web Vitals thresholds should I target for mobile?
LCP under 2.5 seconds, FID/INP under 200ms, and CLS under 0.1. Mobile thresholds are the same as desktop, but mobile connections are slower and devices less powerful, making optimization more challenging and more important.
