Missing viewport tag

The <meta name="viewport"> tag is missing from your page. Without it, mobile browsers display your site as a scaled-down desktop version.

Why it matters

Google uses mobile-first indexing: if your page is not mobile-adapted, it is penalized in rankings for ALL users, including desktop.

How to fix

  1. 1

    Add in the <head>

    html
    <meta name="viewport" content="width=device-width, initial-scale=1">
  2. 2

    In WordPress functions.php

    php
    add_action('wp_head', function() {
      echo '<meta name="viewport" content="width=device-width, initial-scale=1">';
    }, 1);
  3. 3

    If you use a premium theme

    Most modern themes already include this tag. If it is absent, your theme is very likely old and needs an update or replacement.
