## Code

```php
add_filter( 'wp_speculation_rules_configuration', function ( $config ) {
    if ( is_array( $config ) ) {
        $config['mode']      = 'prerender';
        $config['eagerness'] = 'moderate';
    }

    return $config;
} );
```

## Notes

Prerendering runs page scripts early; analytics tools that are not prerender-aware may count extra page views.
