Missing viewport meta
Without a viewport meta tag, mobile browsers render the page at desktop width and zoom out, which fails mobile usability. In a mobile-first index this is a real problem.
What it is
No responsive viewport.
Why it matters
Mobile usability fails; mobile-first indexing penalised.
How to fix it
Add a responsive viewport meta.
How to find it on your site
- View source and check for a viewport meta tag.
- Test the page on a mobile device or in responsive mode.
- Add the standard width=device-width, initial-scale=1 viewport tag.
- Re-test mobile rendering and Search Console mobile usability.
Cross-reference to ranking and citation factors
Mobile usability is part of how Google evaluates pages in a mobile-first index. A missing viewport breaks the mobile experience.
Impact
Medium-high. Direct (mobile-first).
