body: <p>A question regarding the implementation of Facebook Insights metatags.</p>
  
  <p>Must the fb:admins metatag be added to the <code>&lt;head&gt;</code> section of <strong>EVERY</strong> page of a website/domain, or <strong>ONLY</strong> the homepage (root)?</p>
  
  <p>The <a href="http://developers.facebook.com/docs/insights/" rel="nofollow">Insights documentation</a> seems clear:</p>
  
  <blockquote>
    <p>Website owners must add a verification metatag to the <code>&lt;head&gt;</code> section
    of the root webpage of a domain.</p>
  </blockquote>
  
  <p>However, I've checked a number of major sites (Sydney Morning Herald, NY Times, Guardian, Mashable) and implementation varies.</p>
  
  <p>Several sites have neither the fb:admins tag nor the fb:app_id on their homepage, but use at least one of the tags on the following pages.</p>
  
  <p>On other sites, both tags are present on ALL pages.</p>
  
  <p>So...</p>
  
  <ul>
  <li>Should the fb:admins tag be added only to the homepage, or to ALL
  pages?</li>
  <li>Is it a problem if the fb:admins tag is on all pages?</li>
  </ul>
