```php
// Category slugs to keep out of search results.
$wpide_noindex_categories = array( 'internal' );

add_filter( 'wp_robots', function ( $robots ) use ( $wpide_noindex_categories ) {
    if ( ( is_singular( 'post' ) && has_category( $wpide_noindex_categories, get_queried_object_id() ) ) || is_category( $wpide_noindex_categories ) ) {
        $robots['noindex'] = true;
        $robots['follow']  = true;
    }

    return $robots;
} );
```

## Notes

Use category slugs. The category archive pages themselves are noindexed too.
