One of the most useful screens in the OpenX ad server is the zone probability page. There’s an incredible amount of information that you can get from this screen about what’s happening with regards to banner delivery in your zones, if you know how to understand the information presented.
What’s linked and active?
The most immediately obvious information on the zone probability screen is the list of all banners that are linked and active1 in the zone. The fact that the zone probability screen only shows active banners can be useful, as it allows you to easily see the difference between banners that are active in the zone, and any banners that are merely linked to the zone, as shown on the linked banners screen.
