Network ads will be shown to your website visitors if you have no sold site specific ads. In addition, while Network ads can act as revenue-generating placeholders, they are automatically displaced by new site specific ad orders.

If there are no network ads available matching your site, an Advertise Here link will show in it's place.

Keep in mind the system will always attempt to replace image banner ads with text ads if there is inadequate image banner network ads available in that ad size before showing the Advertise Here.
