[NeutralizeR]

If you allow search engines to spider the single versions of your posts (This post, for example... showpost.php), you may want to use adsense ads on this template, too. I think you don't want to miss any possible renevue...

Open your SHOWTHREAD_SHOWPOST template: vBulletin AdminCP > Styles & Templates > Edit Templates > Show Thread Templates > SHOWTHREAD_SHOWPOST

Find:

$postbits

Add above:

<table class="tborder" cellpadding="0" cellspacing="0" border="0" width="100%" align="center">
<tr>
<td class="alt1" align="center">
&nbsp;<script type="text/javascript"><!--
google_ad_client = "youradsensecode";
google_alternate_ad_url = "http://www.yourwebsite.com/collapsible_ad.html";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text_image";
google_ad_channel ="yourchannelcode";
google_color_border = "F5F5FF";
google_color_bg = "F5F5FF";
google_color_link = "FF0000";
google_color_url = "000000";
google_color_text = "22229C";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>&nbsp;
</td>
</tr>
</table>

(Or just the <script> section if you don't want the table.)

You can also add this code after $postbits if you want a second ad unit.
