Have you ever wondered where your Performance Max ads truly run? With the latest Google Ads API v23 update, we finally have the answer!
An exciting change has arrived with the v23 Ads API launch. Now, Performance Max campaign results can be broken down by channel, including Search, YouTube, Display, Discover, Gmail, Maps, and Search Partners. Previously, all your performance data was lumped together, obscuring critical insights.
Here’s the inside scoop. In earlier API versions, I always received a MIXED value for the ad_network_type segment in my Performance Max campaigns. But with v23, these results have transformed into distinct channel enums. It’s a major step forward for those of us who crave precision in reporting and optimization.
Why this matters to us. This update isn’t just about new features — it reshapes how we comprehend Performance Max. With channel-specific reporting now on the table, marketers gain much-needed clarity on where these ads are displayed.
How we can leverage this. Now, we can access channel-level data at the campaign, asset group, and even individual asset levels. This means we can observe how each creative piece performs across Google’s array of platforms. Coupled with v22 segments like ad_using_video and ad_using_product_data, the possibilities for optimizing video performance on YouTube or Shopping ads on Search are endless.
Attention, developers. Upgrading to v23 unveils a level of reporting detail that was previously unreachable. If your system relied on the old MIXED values, it’s time to gear up for the new channel enums.
Keep an eye out for:
- Channel data is accessible only for dates beginning June 1, 2025.
- Remember, asset group–level channel reporting remains exclusively within the API and is not visible in the Google Ads UI.
The takeaway. The newest Google Ads API rollout quietly transforms what was once a black-box campaign category into an analyzable channel-specific type. Finally, advertisers like you and me can dive into the metrics we’ve long sought.
