Here's a simple way to get your Google AdSense skyscraper ads moved to the right of your page.
<TABLE align="right" width="120"><TR><TD>
<script type="text/javascript">
<!--
google_ad_client = 'pub-8749725704400298';
google_ad_width = 120;
google_ad_height = 600;
google_ad_format = '120x600_as';
// -->
</script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js">
</script>
</TD></TR></TABLE>
Just add the bold HTML-snippets before and after your own Ad layout code.
This creates a right-aligned one-celled table.
I'm using this code on my SBI-based website through the SiteBuilder and it works just fine.
