Features Ad Serving
Default and Secondary Zone
A zone can have another zone as default or secondary. In case no ad can be selected from the primary zone, the ad server will try to fetch ads from the default/secondary zone.Chain of Zones
You have the flexibility to create a chain of zones with several layers for a more advanced ad serving sequence. For example: Zone B is secondary to Zone A and Zone C is secondary to Zone B. The ad flow will be A then B then C.How do I show default/house ads after serving all premium inventory?
Because premium ad inventory brings in more revenue, you would like to finish serving these ads before showing house, remnant ad inventory. In order to do this, you would need to create two zones: Zone RemnantHouseAds is the secondary/default zone for zone PremiumAds.Zone PremiumAds links to 3 premium ads (X,Y, and Z). If all ads in zone PremiumAds cannot be displayed because of their restrictions (i.e. ad expires, impression quotas reached, geotargeting failed, etc.), the system will automatically look for ads in the secondary zone RemnantHouseAds.
Exclusivity
If an advertiser wants to place ads exclusively, you can use 3-level zone chaining. The flow of ad selection based on the quality of inventory would be:- Premium/Exclusive Zone: contains only the premium ad(s)
- Standard Zone: contains second-in-priority ads
- Remnant Zone: contains low priority house ads
Considerations
All serving settings, including ad dimensions & all restrictions, are independently applied to ads in the secondary/default zone. For example: if no 468x60 ad in zone PremiumAds can be served and you do not have any 468x60 ad in zone RemnantHouseAds, an error message will be displayed.Example - Fill remnant ad space with ads from ad networks
If your total ad inventory is 500,000 impressions per month but you only sell 300,000 impressions. You want the remaining 200,000 to be ads from ad networks (like Google AdSense). Here is how to set it up:- Create 2 zones: Zone A is for the premium ads, zone B is for ad networks. Edit zone A and set its secondary zone to be zone B.
- Create a new ad, choose the type to be "Rich-Media/HTML" and paste in the Google AdSense tag.
- Link this AdSense ad to the secondary zone. If there is no premium ad available, an ad from secondary zone will be selected.
