Viewport uses fixed width instead of device-width: what it is, why it matters, and how to fix it
The viewport meta tag specifies a fixed pixel width instead of device-width. This prevents the page from adapting to different screen sizes and breaks responsive design.
Where this fits: mobile in SEO
Why viewport uses fixed width instead of device-width hurts your rankings
A fixed-width viewport forces all devices to render the page at a specific width, ignoring the actual screen size. Mobile devices will either show a tiny, unreadable version or require horizontal scrolling. Google's mobile-first indexing penalizes pages that are not mobile-friendly, and a fixed-width viewport is a definitive failure.
This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it.
How to fix it
Change the viewport width from a fixed pixel value to device-width. This allows the page to adapt to the screen width of any device.
