In the Advanced tab of the Zones page you are able to set the following properties:
- Chain settings
- Delivery capping per visitor
Zone chaining
Sometimes a zone cannot display an ad because it is not linked to any active banners, or because delivery limitations prevent it from doing so. To ensure that a blank zone is not displayed you can create a chain of zones. When it is not possible to display a banner for a chained zone then a banner from another zone can be used to replace it. This is why zone chaining can also be used as an effective method of prioritizing your campaigns.
You have two options when initiating zone chaining:
- Stop delivery and don't show a banner: if this option is selected an empty space appears on the website if no banners can be displayed for the zone.
- Display the selected zone instead: selecting this option results in a dropdown menu appearing. Select a zone from it and OpenX will display a banner from that zone if no banners can be displayed for the current zone.
Note: Only zones from the same publisher are available in the dropdown, unless you made zones for another publisher public.
Delivery capping per visitor
You can place a cap (limit) on the number of times a visitor sees an ad in a particular zone. You can cap zones in two ways:
- Limit zone views to...in total: this option caps the total number of times users see the banners linked to this zone.
- Limit zone views to...per session: this option caps the number of times users see banners in this zone in a single session.
- Reset view counters after: OpenX records the number of times a zone has been viewed with cookies. You can order the cookie count to reset after a specified period by entering the desired number of hours, minutes and/or seconds in these fields.
- if a user has disabled cookies banners in capped zones will not be delivered to that viewer.
- if a user deletes existing cookies then the cookie count is reset to zero and the user will see banners in this zone until the set limit is reached.
Once you are happy with your selections, click Save Changes and you will be taken to the Linked Banners tab.
