Quick Reference
Element Code: HT-004
Issue: Page lacks the viewport meta tag for mobile responsiveness
Impact: Poor mobile experience, fails mobile-friendly test, Core Web Vitals issues
Fix: Add viewport meta tag to the head section
Detection: Mobile-Friendly Test, Lighthouse, View Source
What Is This Issue?
The viewport meta tag tells mobile browsers how to control the page's dimensions and scaling. Without it, mobile browsers render the page at a desktop width and then shrink it down, making text tiny and requiring users to zoom and scroll horizontally.
Why This Matters
Mobile Experience
Without the viewport tag, your site is essentially unusable on mobile devices without zooming. Users see a tiny version of your desktop site.
SEO Impact
Google uses mobile-first indexing and considers mobile-friendliness in rankings. Missing viewport tag fails the mobile-friendly test.
Correct Implementation
What Not to Do
- Don't add maximum-scale=1 (prevents zooming)
- Don't add user-scalable=no (accessibility violation)
- Don't set a fixed width like width=1024
TL;DR (The Simple Version)
Your page doesn't have a viewport meta tag. This means mobile users see a tiny desktop version of your site. Add this to your head:
