The Passback functionality is designed for negotiating cases when publishers can not show the advertisers' ads for some reason (targeting limitations, exceeded capping, absence of available ads, etc.). It works both within Epom Ad Server and third-party ad serving solutions.

When Passback is used, unserved impressions will be redirected back ("passed back") to the publisher, so that another ad can be requested, or a house ad can be displayed. Analytics will only show ad requests - and won't count impressions for banners that were not shown.

Note!

Passback is only available for Standard and Non-standard Banners with an HTML Code Banner type.

Passbacks only work for certain combinations of Advertiser and Publisher tags as described in the following table:

    Advertiser
    JS Sync JS Async Iframe Sync Iframe Async Simple Iframe Direct URL
Publisher Iframe Sync + + + + - -
Iframe Async + + + + - -
JS Sync + + + + - -
JS Async - + - - - -
Simple Iframe - - - - - -
Direct URL - - - - - -

There are two possible cases:

  1. You are an advertiser, and your publisher provides you with a passback tag.
  2. In this case whenever a banner is not shown, the publisher's default code (ad, image, etc.) will be displayed.

  3. You are a publisher, and you provide your advertiser with a passback tag.
  4. In this case the passback tag will attempt to display another banner, or won't score an impression if there are no alternative banners available for display.

The First Case

If your publisher provides a passback tag to you, you need to:

  1. Go to the Publishers tab and navigate to the Site > Zone > Placement for which you need the passback to be configured.
  2. Insert the passback tag provided by your Publisher into the Default Code field and click Save.

Now, whenever the banner or banners linked to this Placement fail to be shown, the Default Code will be processed.

The Second Case

Lets assume that there is a Placement with several banners linked to it. For some reason, the advertiser that serves one of the banners could not have it displayed. With the passback functionality configured, another banner with the same passback tag will be requested, and the impression will be counted only towards the banner that will be shown.

To configure the Passback:

  1. Log into your network account and go to the Advertiser > Campaign > Banner for which you'd like the Passback to be set.
  2. Select the Enable Passback Functionality checkbox.
  3. Enable Post Message Passback checkbox will appear. Select it as well.
  4. Banner passback code field will be displayed:
  5. Copy the code and pass it to advertiser 'as is'.

Passback code should be 'called' when advertiser has no ads that meet the request.
