Impression Tracker service

  • Artigo

The Impression Tracker Service gives you a way to track impressions for creatives served by third-party ad servers (rather than by AppNexus).

Here's how it works:

  1. You use the Impression Tracker Service to create an impression tracker. The impression tracker specifies the line item and publisher to which it is associated. Optionally, it can include the specific placement or payment rule to which it is associated.
  2. You create an image or JavaScript tag with the URL to the impression tracker and ask the ad server to use it as a piggyback pixel for the creative. The impression tracker URL must be formatted as https://ib.adnxs.com/imptr?id=12345&t=2, where 12345 is the impression tracker ID and "t" represents the pixel type (where t=1 is for javascript and t=2 is for image).
  3. When the ad server serves the creative, the tracker calls ib.adnxs.com, and AppNexus records the impression.

Query string parameters

The following parameters can be passed to AppNexus in the query string of the impression tracker URL:

Parameter Description
cachebuster Prevents the user's browser from caching the impression tracker URL. This parameter can be populated by the third-party ad server.
ancost The media cost you paid for the impression. The parameter can be populated by the third-party ad server.
redir The redirect URL that AppNexus will redirect to once the impression has been recorded.

Image tag example

<!-- Imp Tracker - Test Impression Tracker - DO NOT MODIFY -->
<img src="media/imptr?id=531&cachebuster=[CACHEBUSTER]&ancost=[ANCOST]" width="1" height="1" />
<!-- End of Imp Tracker -->

JavaScript tag example

<!-- Imp Tracker - Test Impression Tracker - DO NOT MODIFY -->
<script src="https://ib.adnxs.net/imptr?id=531&cachebuster=[CACHEBUSTER]&ancost=[ANCOST]" type="text/javascript"></script>
<!-- End of Imp Tracker -->

Reporting

You can report on your external impressions using the Network Analytics, Network Publisher Analytics, and Publisher Analytics reports.
