User scaling disabled in viewport — the fix
The viewport meta tag includes user-scalable=no or maximum-scale=1, preventing users from zooming in on the page. This is an accessibility violation and poor user experience.
Where this fits: mobile in SEO
Google indexes the mobile version of your site — desktop is the afterthought, not the other way round. Mobile issues (missing viewport, tap targets too close, content wider than the screen, intrusive interstitials) directly gate rankings for every query. With most traffic on phones, a mobile problem is not a subset of your audience — it is your audience.
Why user scaling disabled in viewport hurts your rankings
Disabling pinch-to-zoom prevents users with low vision from enlarging text and content to a readable size. This is a WCAG 2.1 Level AA violation (Success Criterion 1.4.4) and is flagged by Lighthouse as an accessibility issue. Google considers accessibility as part of overall page quality assessment.
This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site.
How to fix it
Remove user-scalable=no and maximum-scale=1 from the viewport meta tag. Allow users to zoom to at least 500% per WCAG requirements.
<!-- Before -->
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no, maximum-scale=1" />
<!-- After -->
<meta name="viewport" content="width=device-width, initial-scale=1" />Mobile best practices
- Ship a correct viewport meta tag on every page — it is one line and it gates everything.
- Keep tap targets ≥ 44×44px with real spacing between them.
- Never let content overflow the viewport horizontally.
- Test on a real mid-range phone over 4G, not just desktop devtools.
- Avoid intrusive interstitials — Google demotes pages that greet mobile users with a wall.
