Third-Party Tags and Pixels Implementation Request
Last January it was announced that YouTube will move away from using third-party ad tracking pixels.
As of May 21, 2018, only a small group of vendors are certified for measurement on YouTube: comScore, DoubleVerify, IAS, MOAT, Nielsen, Kantar, Research Now, and Google (including Google Marketing Platform). For Video ads, Google Ads no longer accepts third-party ad tracking pixels that are not from one of these vendors or that make unapproved fourth-party calls to other vendors.
The Google Ads team is taking steps to ensure that existing ads comply with this new policy. Learn more about how to ensure that your existing ads comply with this new policy.
