title: How do I claim a URL for Facebook Instant Articles
body: <p>When I try to claim my URL I get this error: </p>
  
  <p><code>The fb:pages tag on the url doesn't contain this page's id. The url has
  fb:pages tag but they don't have this page's id. Please work with your
  developers / webmaster to add this tag to your website.</code></p>
  
  <p>Am I supposed to place this meta tag: <code>&lt;meta property="fb:pages" content="130810137587****" /&gt;</code> in the head of my web page's HTML before I can calm my URL? Or in the head of my Instant Article's HTML
  ?</p>
