Dear Partner,
We're writing to inform you of an upcoming policy clarification regarding traffic sourced to your sites.
Overview of changes: To ensure the accuracy and effectiveness of our systems, all publishers will soon be required to provide the
referrerAdCreative parameter (RAC) [developers.google.com]
when traffic arrives to a Related Search for Content page from a source that is under your control. This includes any third party network, service or affiliate you partner with.
In such instances, you're required to set the parameter to the precise and complete creative text of the advertisement or link source. To elaborate, "precise and complete creative text" signifies a literal transcription.
For example, within an upstream video source featuring an influencer walking down a street, speaking to the camera, with background music also present, the full transcript of the speech, the song lyrics, and any visible text on street signs, among other elements that might appear anywhere on the user’s screen, must be provided verbatim and in their entirety.
Omitting to do so will be considered a policy
violation. [support.google.com]
For details, review
the best practices to use related search [support.google.com] help center article.
Reminder: In addition to RAC, all usage of Related Search for Content must adhere to requirements, and provide accurate declarations for parameters per the
implementation guide. [developers.google.com]
This change will come into effect on November 1, 2025.
Sincerely,
The Google AdSense Team
