Add a viewport meta tag

Why it matters

Without a viewport tag, phones show the page as a tiny desktop layout. Google indexes the mobile version of your site, so a page that is not mobile-ready can rank lower.

The fix

1. Add the viewport meta tag to the head of every page. Do not add user-scalable=no or a maximum-scale below 5, which stop visitors from zooming.
2. Check that your CSS actually adapts to narrow screens, then open the page on a phone or in the DevTools mobile view.

<meta name="viewport" content="width=device-width, initial-scale=1">
