Your page is missing the viewport meta tag. This is the single most important tag for mobile-friendliness. Without it, mobile browsers will try to display your page as if it were on a desktop screen, forcing users to pinch and zoom to read anything. This is a critical issue for both user experience and mobile SEO.
The HTML <head> does not contain a `<meta name="viewport">` tag.
Add the standard viewport meta tag to the <head> of your HTML.
<meta name="viewport" content="width=device-width, initial-scale=1.0">The viewport tag is the instruction that tells browsers how to control the page's dimensions and scaling, effectively 'turning on' your responsive design. It is a non-negotiable requirement for a mobile-friendly website.
This issue can affect your site's search engine rankings and user experience. Addressing it promptly helps ensure optimal performance and visibility in search results.
