title: How to set dynamic Meta Tags and Open Graph tags in polymer?
body: <p>I have a polymer node site that I've been working on and can't figure out how to include dynamic meta tags and Open Graph tags. Jquery won't work and neither will using the polymer api to add a node because it will add all the tags after the page loads and facebook won't be able to read the tags.  Google crawlers do render the page but it would be best if I could set the description in the header.</p>
  
  <p></p>
  
  <pre><code>&lt;html&gt;
    &lt;head&gt;
      &lt;meta name="description" content="description goes here" /&gt;
      &lt;meta property="og:title" content="title"/&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;group-pages id="grouppages" is="dom-bind"&gt;&lt;/group-pages&gt;
    &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>grouppages sets the data and uses a services to populate the page based off the url but what I can't find out is how to change the meta tags depending on the page.</p>
  
  <p>Anyone have any ideas?</p>
  
  <p>One thought was get information server side and send it in to polymer but I'm still not sure if that's possible between node and polymer.</p>
