By adding a name to your route such as

Route::post('site/update/{id}', 'siteController@update')->name('site-update');

It allows you to generate its URL without knowing it at all

<form method="post" action="{{ route('site-update', compact('id')) }}">
@csrf
add your form field here and use button type submit
</form>

Even if you decide to change the URL, the route helper does not care as long as the name stays the same (it's just an alias)
