Google Ads has confirmed a technical issue that is impacting Discovery campaigns.

The platform is in the process of trying to resolve the error, which is causing some account-level site and app category exclusions to prevent the delivery of Discovery ads to Google properties such as Gmail.

A spokesperson explained that these exclusions “aren’t intended to apply to Google properties”.

The notification from Google Ads was shared on X (formerly known as Twitter) by digital advertising expert, Menachem Ani:

Why we care. Discovery campaigns maximise results by delivering ads to YouTube, Gmail, and the Discover feed. If an error is preventing the tool from delivering ads to Google properties, it will negatively impact reach, which will subsequently affect conversion and ROI.

When will the problem be fixed? Google Ads has not yet shared when a fix can be expected, however, we’ll be keeping an eye on things.
