For the banners to show up on your website you will need to place some code for the Ad Zones you have created, there are 3 ways you can do this. While on the Ad Zones page ( choose Ad Zones from the plugin menu) expand the “Current Ad Zones” menu at the bottom and you will see all the zones listed :

Click “View” next to the Ad Zone you would like to place and it will slide down with some code like so :

If you would like to place the Ad Zone code in a theme file, use the PHP code – you can paste this into any WordPress theme file. The second option is a shortcode – you can paste this in any WordPress post or Page and the Ad Zone will show there.

The 3rd and final way to show an Ad Zone is via a Widget, visit “Appearance” > “Widgets” and you will see a new widget called “WP AdCenter” – drag this to the place on your theme you want it to appear and then choose which Ad Zone you’d like to show from the drop down menu.
