the <meta name="viewport"> tag required for mobile

Why meta viewport test still matters in 2026
Google now indexes mobile-first: if your mobile version has a problem, that's the one Google evaluates, no matter how beautiful the desktop is.
The newer reason: AI answer engines and link previews
Mainstream AI tools are massively used on mobile. If your mobile version is broken, the post-click experience ruins your credibility and the AI engine stops citing you.
Common mistakes worth checking
Text too small, unreadable without zooming.
Buttons too close to one another (tap targets).
Fixed pixel width breaking on mobile.
Slow carousels or ones that can't be used by finger.
Intrusive mobile pop-ups (penalized by Google).
