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;
} );
```
