Comment on SEO AdSense WordPress Theme by SEO Dave.
Under the Stallion AdSense Options page set the Main Content Ad Unit to Off.
This disables it sitewide.
Set Sidebar Content Ad Unit Extra to On.
This adds an extra AdSense widget which you can use to replace the one we are about to use to replace the disabled one. We are going to use a sidebar ad unit as the main content ad unit so need a replacement.
Under Appearance Widgets add the Stallion AdSense Content S1 Widget (important it’s this AdSense widget) to the the Content Ad Widget Area.
This will show the AdSense ad sitewide where the main content Ad unit normally is, now use the Hide On Checked widget option I described in my last comment to hide the widget on areas of the site you want it hidden on.
There’s otherways of doing this like editing template files, but this is the only way I can think of without editing files.
