About this free viewport meta checker

Mobile-first indexing means Google primarily uses the mobile version of your site. Without a proper viewport meta tag, layouts break on phones.

Verify viewport configuration before you debug Core Web Vitals or mobile usability in Search Console.

  • Common width=device-width patterns

Why it matters for SEO

  • Required baseline for responsive design and mobile SEO.

How to use this tool

  1. Test homepage and key templates.
  2. Add width=device-width, initial-scale=1 if missing.
  3. Retest in mobile-friendly tests after theme changes.

Common issues we help you catch

  • No viewport tag on legacy templates
  • user-scalable=no harming accessibility
  • Fixed-width layouts on commerce themes
