Help Center Features Ad Serving

Default and Secondary Zone

A zone can have another zone as default or secondary. In case no ad could be chosen for the primary zone, the system will try to fetch ads from the default/secondary zone.

Chain of Zones

You have the flexibility to create a chain of zones 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 -> B -> 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 -> Standard -> Remnant

When you link ad ad to an exclusive zone, it will be the only ad to display. When this ad expires (falls out of start/end date), our system will look into the standard zone next. You don't have to apply any restriction to the ads in standard zone as they'll be considered only when there is no ad in the exclusive zone.

Considerations

All serving settings, including ad dimensions & all restrictions, are independently applied to ads in the secondary/default zone. Therefore, 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.
