01The Direct Answer
How do I know where Performance Max is spending my money?
Direct Answer
Open the channel performance report inside the campaign, which now breaks spend down by network instead of hiding it behind one automated number.
According to Google Ads Help, the report covers Search, Display, YouTube, Discover, Maps, Gmail and search partners, and it accepts date ranges from June 6, 2025 onward — an earlier campaign history simply is not covered. For an industrial buyer who assumed Performance Max meant "more search", that report is often the first time the actual mix becomes visible.
02Why It Was a Black Box
One campaign type, seven networks, one number
Performance Max was built to let Google decide, campaign by campaign and impression by impression, which of its networks best serves the goal set for it. That design is the reason it can outperform manually split campaigns in some cases, and it is the same reason an advertiser historically had no visibility into the split it produced.
For a technical product with a small, specific buyer, that opacity is a real cost: video impressions on YouTube or Discover cards can absorb budget that would have produced a search click from someone actively looking for a supplier, and without a channel breakdown there was no way to tell the two apart.
03What the Channel Report Shows
Seven lines instead of one
Reading It in Practice
1. Open the channel tab
Inside the Performance Max campaign, filter by a date range from June 6, 2025 or later.
→
2. Sort by spend
See how much went to Search versus Display, YouTube, Discover, Maps and Gmail.
→
3. Compare against conversions
A channel with high spend and few conversions is a candidate for a separate, controllable campaign.
According to the Google Ads blog, the report was announced in beta on April 30, 2025 alongside a promise of a fuller search terms report coming to Performance Max, which means the visibility into this campaign type keeps improving and is worth rechecking periodically rather than reviewed once and forgotten.
04The Limits of Negatives in Performance Max
A negative keyword does not reach every channel
According to Google Ads Help, negative keywords in Performance Max only affect Search and Shopping inventory inside that campaign, not Display, YouTube, Discover, Maps or Gmail. Brand exclusions work differently and remove traffic tied to the listed brands specifically, which is the closer tool if the goal is keeping distributors or resellers out of your own campaign.
For the industrial-specific negative list to pair with this, see the B2B Google Ads service page, where account structure and channel review are handled together.
05FAQ
FAQ
How do I know where Performance Max is spending my money? +
By opening the channel performance report inside the campaign. According to Google Ads Help, it breaks spend down across Search, Display, YouTube, Discover, Maps, Gmail and search partners, and accepts date ranges from June 6, 2025 onward.
When did this channel report become available? +
According to the Google Ads blog, the channel performance report was announced in beta on April 30, 2025, and Google Ads Help states it accepts date ranges starting June 6, 2025. Spend from before that date is not broken out by channel.
Do negative keywords work inside Performance Max? +
Only partially. According to Google Ads Help, negatives in Performance Max affect only Search and Shopping inventory, not Display, YouTube, Discover, Maps or Gmail. Brand exclusions are a separate control for keeping specific brand traffic out.
Can I stop Performance Max from spending on YouTube or Display entirely? +
Performance Max is designed to allocate across its full set of channels, and Google Ads Help does not document a way to exclude a whole channel from it. If channel control matters more than the automation, the alternative is running separate campaigns per network instead of Performance Max.
Is Performance Max bad for industrial companies? +
Not inherently. It is a tool built for automated allocation across networks, which can work well when the conversion signal fed into it is accurate. The risk for an industrial account is running it while still optimizing for forms instead of qualified leads, which lets the automation spend confidently on the wrong audience.
What is a healthy channel split for an industrial account? +
There is no published benchmark for this split by industry. The useful comparison is internal: track cost per opportunity by channel over a few months and let that history, not an external rule, decide how much weight each channel deserves.
Does the channel report replace the search terms report? +
No, they answer different questions. The channel report shows which network the budget went to; the search terms report shows which query triggered the ad. According to the Google Ads blog, a fuller search terms report for Performance Max was announced alongside the channel report, so both are worth checking together.
What should I do if a channel is spending a lot with no conversions? +
Since Performance Max does not let you exclude a whole channel, the practical options are adjusting the campaign's assets and audience signals to steer it away from that inventory, or moving the budget into a separate campaign type that gives direct channel control.
