Found it. It is for the Google Analytics code. I want it on each page but don't want to have to remember to try to include it. A script would help :)
<script type="text/javascrip">
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-3XXXXXX7-1']);
_gaq.push(['_trackPageview']);
(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl'; : 'http://www';) + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();
</script>
Dynamic Content Implementation optional
Use a common include or template to paste the code above instead of manually adding it to every page
