Where do you place the following Javascript-part:

Code:

<script type="text/javascript" src="http://www.yourdomain.com/stat/track.php?mode=js"></script>
<noscript><img src="http://www.yourdomain.com/stat/track_noscript.php" border="0" alt="" width="1" height="1"></noscript> 

In a website which uses Wordpress?

Do you enter it in every posting you make? Or just in the index.php / home.php pages?

Please advice. I am afraid of doing something wrong here.
