If you wanna track your website stats with google analytics you have put the code before , which is a piece of cake usually in any html website. But in SMF you have to put it inside the echo '' of php. I have done the tough part, just follow these steps:
Find:
echo '
</body></html>';
Replace it with:
echo '
<div id="ajax_in_progress" style="display: none;', $context['browser']['is_ie'] && !$context['browser']['is_ie7'] ? 'position: absolute;' : '', '">', $txt['ajax_in_progress'], '</div>'
//Begin Google Analytics
?><script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-#######-#");
pageTracker._trackPageview();
} catch(err) {}</script><?php echo '
</body></html>';
Put your code here in place of UA-#######-#.
Let me know if you have issues.
