   Example of adding a noindex robots tag.

   add_filter( 'wp_robots', function( $robots ) {
   	$robots['noindex'] = true;
   
   	return $robots;
   } );

   To affect pages with a certain page template, you can add this directly to the template, as long as it’s above the call to wp_header().

   To have more granular control over what pages are affected, you can add the snippet to your functions.php file and work with the current page inside the function:

   add_filter( 'wp_robots', function( $robots ) {
   	$id = get_the_ID();
   
   	if ( 19 === $id ) {
   		$robots['noindex'] = true;
   	}
   
   	return $robots;
   } );
