Performance Max just got a lot less mysterious.
With the release of Google Ads API v23, advertisers can now see Performance Max (PMax) results broken down by channel instead of lumped into one mixed bucket. For marketers who have long asked where their PMax budget is actually going, this update is a big deal.
What Changed and Why It Matters
Google quietly rolled out one of the most important Performance Max updates to date. As of Google Ads API v23, advertisers and developers can now report PMax performance by specific channels such as:
- Search
- YouTube
- Display
- Discover
- Gmail
- Maps
- Search Partners
Previously, PMax campaign data was mostly returned as a single MIXED value under the ad network type. That made it hard to understand which Google surfaces were driving results and which ones were wasting money.
Now, that black box is starting to open.
This update matters because better visibility leads to better optimization, smarter budget allocation, and stronger ROI from google ads campaigns.
The Technical Shift Under the Hood
Before v23, the Google Ads API typically returned ad_network_type = MIXED for Performance Max campaigns. This meant reporting tools, dashboards, and internal analyses had to rely on assumptions rather than real channel data.
With v23, that MIXED value is replaced with specific channel enums, giving advertisers access to granular performance insights that simply were not available before.
In short:
- Old versions showed blended data
- v23 shows real channel-level breakdowns
This is not just a cosmetic change. It fundamentally alters how PMax can be analyzed and optimized.
Why Advertisers Should Care Right Now
For businesses investing heavily in google ads, Performance Max has always promised automation and reach. But the trade-off was limited transparency.
This update changes that equation.
With channel-level reporting, advertisers can now:
- See where their ads actually appear
- Understand which channels drive conversions
- Identify underperforming placements
- Align creatives with the right platforms

For anyone serious about google ads management, this update finally provides the data needed to make informed decisions instead of guesses.
How Marketers Can Use Channel-Level PMax Data
The new reporting is available across multiple layers, including:
- Campaign level
- Asset group level
- Individual asset level
That means advertisers can analyze how each creative performs across different Google properties.
When combined with earlier API features like ad_using_video and ad_using_product_data, teams can now isolate insights such as:
- Video performance specifically on YouTube
- Shopping-style ads on Search
- Display creative effectiveness across the Display Network
This is especially powerful for brands using full-funnel strategies and advanced ppc management services.
Our Expert Take from Tech Support Plus IT Services
From a professional google ads management perspective, this update signals a major shift in how Performance Max should be handled.
Here is what we recommend businesses do next:
- Upgrade reporting systems to API v23 as soon as possible
- Audit existing PMax campaigns using the new channel data
- Identify channels that consistently underperform
- Refine asset groups based on channel performance, not assumptions
- Adjust budgets with real data backing every decision
For advertisers who felt unsure about where their PMax spend was going, this update finally restored confidence and control.
At Tech Support Plus IT Services, we see this as a turning point. Performance Max is no longer just about trusting automation. It is now about guided automation powered by real insights.
What Developers Need to Know
Developers and analytics teams should note one critical point. Reporting systems that relied on the old MIXED value must be updated.
If your dashboards or scripts are not prepared to handle the new channel enums, reporting errors or missing data may occur.
Upgrading to v23 is not optional if you want accurate and future-proof reporting for search engine marketing.
Bottom Line
The latest update from Google may have flown under the radar, but its impact is huge.
Google Ads API v23:
- Breaks down Performance Max by channel
- Improves transparency and trust
- Enables smarter optimization
- Turns PMax into a more strategic campaign type

What was once a black box is now something advertisers can finally analyze with confidence.
