title: Editing the preview of a link on facebook
body: <p>I have launched a new website for a few days. When I copy and paste the links of adverts on Facebook, the preview is not correct, I mean that the image and the title of the advert are not displayed despite that I added the tags <code>&lt;meta property = "og:title "&gt;</code> and <code>&lt;meta property ="og:description"&gt;</code></p>
  
  <p>Here is a piece of source code:</p>
  
  <p><code>
      &lt;meta property="og:image" content="https://www.coinemploi.com/assets/images/logo_lg.png"&gt;
      &lt;meta property="og:type" content="website"&gt;
      &lt;meta property="og:site_name" content="coinemploi.com"&gt;
      &lt;meta property="og:locale" content="fr_FR"&gt;
      &lt;meta property="og:url" content="https://www.coinemploi.com/jobs/show/6/des-teleconseiller-tunis-h-f"&gt;
      &lt;meta property="og:title" content="Des téléconseiller - tunis  (h/f)"&gt;
      &lt;meta property="og:description" content="Offre d'empoi Des Téléconseiller - Tunis  (H/F) à Tunis, Tunisie - CDD / Intérim / Mission - CDI - Temps Plein - SIVP - Centre d’appels - entreprise Manwork"&gt;
  </code></p>
  
  <p>and here is how it's displayed on Facebook</p>
