Answer 1

Correct the controller and the view like this
landing-page.blade.php
<div id="simplelastads">
<h2>Les dernières annonces</h2>
<div class="contentads">
#foreach($categories as $category)
<div class="simpleadsemploi">
<h3>{{ $category->name }}</h3>
#foreach($category->annonces as $annonce)
<div class="tab_left">
<div class="li-child">
{{ $annonce->titre }}
<span>{{ $annonce->ville }}({{ $annonce->hay }})</span>
</div>
<div class="readmore">Voir plus...</div>
</div>
#endforeach
</div>
#endforeach
</div>
</div>
Use the eager loading for the annonces to improve performance with('annonces')
LandingPageController.php
public function index()
{
$categories = Category::with('annonces')->get();
return view('landing-page')->with([
'categories'=> $categories
]);
}
