Publisher certification should be initiated only if publisher is able to accept third-party tags and adheres to the IAB Standards.

This workflow can be used both by advertisers/agencies or by publishers:


If advertiser/agency wants to work with a specific publisher and would like to proactively test Adform ads on publishers site in order to be sure that ad serving and creative functionality would work as expected.


If publisher wants to proactively test Adform ads on their site in order be able to confirm to Advertisers that ad serving and creative functionality would work as expected.

Below are steps for testing:

  1. Advertiser/agency or publisher decides which ads they want to test (from the below table)

  2. Publisher downloads needed tags and implements them in a live/test environment (Adform Tags implementation guide)

  3. Publisher provides test page URLs to Adform Support at [email protected]

  4. Adform Support verifies ad serving and creative functionality

All communication regarding ad formats selection for testing should be held and initiated by advertiser/agency and/or publisher. Adform Support provides assistance on verifying ad serving and creative functionality once tags are implemented in a live/test environment.

Below listed tags are designed for ad serving and creative functionality testing but not for discrepancy check. For standard certification, it’s enough to test ad serving and creative functionality to ensure accurate reporting. If there is a specific need to perform a discrepancy check, please contact Adform support at [email protected] for more information.
