title: Using og:locale:alternate to list multiple countries using this language
body: <p>I support 5 languages on my website (en, fr, de, es, it). Each page has 5 URLs based on the language:</p>
  
  <ul>
  <li><a href="https://mywebsite.com/en/mywebpage" rel="nofollow noreferrer">https://mywebsite.com/en/mywebpage</a></li>
  <li><a href="https://mywebsite.com/fr/mywebpage" rel="nofollow noreferrer">https://mywebsite.com/fr/mywebpage</a></li>
  <li>...</li>
  </ul>
  
  <p>I don't have specific content based on the country so an English speaking person from the US and a English speaking person from the UK will get the same content.</p>
  
  <p>As I have to specify a country for og:locale, should I pick one of the country for og:locale and use og:locale:alternate to list all the other countries where this language is used?<br>
  For example, for the English webpage, should I have the following?  </p>
  
  <pre><code>&lt;meta property="og:locale"  content="en-US" /&gt;
  &lt;meta property="og:locale:alternate"  content="en-GB" /&gt;
  &lt;meta property="og:locale:alternate"  content="en-CA" /&gt;
  </code></pre>
  
  <p>Or should I choose one og:locale (en-US for this example) and let Facebook do the rest?</p>
