You can put it right after this here:
<body <?php body_class() ?>>
There is a page for each zone you have setup for your site. On your Publisher dashboard, hover over the “actions” dropdown for each zone to see the “ad code” view.
We actually just released a “proposal” feature that helps you sell directly to an advertiser at a lower commission rate: http://buysellads.com/sell/proposals
The thinking behind the 15% is:
– 3.5% or so for payment processing
– the rest for us handling all support, billing issues, and providing the advertiser with a place to manage the ads on their own, see stats, etc.
Would love to hear any thoughts you have if/when you check this out.
