ads banner

Adsense limit 3 ads per page. If i insert adsense ads in node.tpl.php, it well repeat the ads 3 times. Because of the node load first before the bottom block, my adsense in bottom block no showing. To solve this, add this snippet inside node.tpl.php. It nice also to separate teaser and full page theme and only insert this snippet inside teaser section only

<?php
if ($id == 1 && $is_front) {
print "...banner here...";
}
?>
