<if condition="$bbuserinfo['usergroupid'] == 1">

means they only show for usergroup with the ID of 1

That usergroup is Unregistered / Not Logged In.

So only guests will see the ads as you added the IF statement to only show them the ad's :P

<div style="float:right; width:300px; height:250px; margin-left:10px">

<script type="text/javascript"><!--
google_ad_client = "pub-3468565034734280";
/* 300x250, created 5/29/09 */
google_ad_slot = "4032835295";
google_ad_width = 300;
google_ad_height = 250;
//-->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>

</div>

should work as theres no usergroup specified.
