Piwik (analytic software) works by including a small script just before </body>:
<script type="text/javascript">
var _paq = _paq || [];
_paq.push(['trackPageView']);
_paq.push(['enableLinkTracking']);
(function() {
var u="//piwik.example.com";
_paq.push(['setTrackerUrl', u+'piwik.php']);
_paq.push(['setSiteId', 1]);
var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
g.type='text/javascript'; g.async=true; g.defer=true; g.src=u+'piwik.js'; s.parentNode.insertBefore(g,s);
})();
</script>
This script will include piwik.js(basically this script ) from your piwik installation on the page. piwik.jsrecords a few things (screen size, ip, etc.) and sends them to your piwik installation in a GET request to register a pageview.
Now I don’t understand why you didn’t just include piwik.js on your page right away. Why worry about pulling it out of a separate place when you can just concatenate and minimize it with the rest of your scripts?
