If you want to redirect the user within the Facebook Page tab iframe, then depending on your website language you can easily achieve this. In PHP for instance: header("Location: my_page.php");

Otherwise, if you want to redirect the user to your website outside Facebook, you use something like:

<script>top.location.href="http://example.com/page.php"</script>
