Viewport Meta

Checks for proper viewport meta tag

Solution

The viewport meta tag is essential for responsive design. Use: <meta name='viewport' content='width=device-width, initial-scale=1'>. This ensures proper scaling on mobile devices. Without it, mobile browsers render at desktop width and zoom out. Required for mobile-first indexing.
