  <!-- / Yoast SEO plugin. -->

Um Yoast SEO zu ersetzen, müssen diese Einträge aus der functions.php generiert werden. Dabei sollen die Inhalte dynamisch gemacht werden.

Aus der Wordpress-Dokumentation:
  function themename_custom_header_setup() {
    $args = array(
        'default-image'      => get_template_directory_uri() . 'img/default-image.jpg',
        'default-text-color' => '000',
        'width'              => 1000,
        'height'             => 250,
        'flex-width'         => true,
        'flex-height'        => true,
    );
    add_theme_support( 'custom-header', $args );
  }
  add_action( 'after_setup_theme', 'themename_custom_header_setup' );

Nützlicher (von https://wordpress.stackexchange.com/questions/293018/add-meta-tags-to-the-head-section-via-functions-php)
  // echo noindex tag if post or page has a "my_noindex" custom field with a value of "y"|"Y"|"yes" ...
  function my_meta_tags() {
   $noindex = (get_post_meta( get_queried_object_id(), 'my_noindex', true ));
   if (strtolower(substr($noindex,0,1)) == 'y') { 
     ?><meta name="robots" content="noindex" />
     <?php return; // noindex so no point in doing any other SEO stuff
   }

   // other SEO stuff

  }
  add_action( 'wp_head', 'my_meta_tags',2);
