i assume for google analytics, they give you a script to paste in your..

like this:

Code
<script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
</script>
<script type="text/javascript">
  _uacct="UA-XXXXXX-X";
  urchinTracker();
</script>

urchin.js was what i termed it as, but it's really the whole script..
