Fix: Mobile Friendly

Google indexes and ranks primarily based on the mobile version of your site (mobile-first indexing) — if your site isn't genuinely usable on a phone (tiny tap targets, content wider than the screen, unreadable text), that's the version Google is actually judging you on.

Google indexes the mobile version of your site first. A missing viewport tag or tap targets that are too small mean a poor mobile experience — which directly caps your rankings.

How to fix it

1. 1
   Test on an actual mobile device, not just a resized browser

   Real touch targets, real font rendering, and real viewport behavior differ meaningfully from a desktop browser resized smaller.
2. 2
   Check tap target sizing

   Buttons and links need enough size and spacing to tap accurately with a thumb — this is a specific, checkable Lighthouse audit item.
3. 3
   Fix any horizontal scrolling

   Content wider than the viewport forces sideways scrolling — usually caused by a fixed-width element or an unresponsive embed.
4. 4
   Verify text is readable without zooming

   Base font size should be legible at actual phone screen size, not requiring a pinch-zoom to read.
