Is there an easy way to include a Facebook remarketing tag in my D7 site? Adding Google Remarketing Script tags to Drupal 7 website shows how to add a Google remarketing tag using a module. Is there a similar solution for adding a Facebook remarketing tag easily?

I would use the drupal_add_js hook if that were so easy, but the issue is that the remarketing tag also includes an &lt;img/&gt; element (the pixel) in a &lt;noscript&gt; tag, so I can't include that easily in the same hook.
Turned out to be very simple. All I had to do was paste the code into the &lt;head&gt; part of html.tpl.php from within the /templates/ folder.
