body: <p>I'm working on a project generated with vue CLI 3, i went to the public folder and inserted the following meta tags inside the head:</p>
  
  <pre><code>&lt;meta property="og:site_name" content="My Site"&gt;
  &lt;meta property="og:title" content="My Site" /&gt;
  &lt;meta property="og:description" content="Description" /&gt;
  &lt;meta property="og:image" itemprop="image" content="http://mysiteurl.com/image.jpg"&gt;
