## Code

```php
add_filter( 'woocommerce_loop_add_to_cart_link', function ( $html, $product ) {
    if ( $product->is_type( 'external' ) && false === strpos( $html, 'target=' ) ) {
        $html = str_replace( '<a ', '<a target="_blank" rel="noopener sponsored" ', $html );
    }

    return $html;
}, 10, 2 );

add_action( 'woocommerce_after_add_to_cart_form', function () {
    global $product;

    if ( ! $product instanceof WC_Product || ! $product->is_type( 'external' ) ) {
        return;
    }

    echo "<script>document.querySelectorAll('form.cart').forEach(function(f){ if (f.getAttribute('method') === 'get') { f.setAttribute('target', '_blank'); f.setAttribute('rel', 'noopener sponsored'); } });</script>\n";
} );
```

## Notes

Adds rel="noopener sponsored" to the links, which is recommended for affiliate links.
