Mobile
We read the viewport meta, charset, srcset/sizes and image dimensions. This is HTML from the server — not a real phone lab.
Frequently asked questions
- Is this a mobile usability report like Search Console?
- No. Google uses a real renderer. We only inspect the HTML: viewport, srcset and layout hints.
- What should viewport contain?
- width=device-width, initial-scale=1. Without it, phones zoom the desktop layout.
