A banner can be linked to a zone.
In order to display a given banner to a website visitor, the desired banner that should be shown needs to be associated (i.e. linked) to the relevant zone(s) for the website. This way, Revive Adserver knows which banners to display when the relevant zone invocation tag is invoked on a website.
As well as linking banners to zones at the campaign level, a banner can be linked to a zone at the banner level.
Inventory > Banners
To link a banner to a zone, go to Inventory > Banners:
Banner properties > Linked Zones
If necessary, use the drop down menu to select the appropriate advertiser and/or campaign, and then click on the appropriate banner name. This will take you to the Banner properties screen. Click on the Linked Zones tab.
Revive Adserver will display only those zones (grouped by their parent websites) that have an appropriate type and size for the current banner. Select (or deselect) the zone(s) you wish to link the banner to, or unlink the banner from, and click on Save Changes to save your changes.
