If you run a store that already does real volume on Google, you do not need another "what is PMax" explainer. You need to know what moved, whether it changes a decision you make this quarter, and where it affects per-order profit. That is what this covers.
What actually shipped in November 2025
Two things landed on November 6, 2025, per Dataslayer's write-up: channel performance reporting expanded to all advertisers, and Waze ads joined the inventory for store-goals campaigns.
Channel reporting is now live for every account
The channel performance report breaks your PMax spend and results out by Google surface — Search, Display, YouTube, Discover, Maps, and Gmail, with search partners following in the weeks after launch. It reports clicks, conversions, conversion value, and cost per channel, Google's help documentation confirms.
This feature was not new in November. The data has been viewable for date ranges after June 6, 2025, and the rollout was announced back in April; November is when it finished reaching accounts broadly, as Search Engine Journal reported. If you log in and the report is finally there, that is the November milestone.
Manager-account access came with it, so if you run several stores you can read channel splits across the portfolio instead of clicking into each account one at a time.
Waze ads entered the store-goals inventory
The second update adds "Promoted Places in Navigation" pins on Waze to Performance Max for store-goals campaigns, reaching the app's active drivers, Dataslayer notes. It is United States only at launch, with other markets slated for 2026, and it reuses your existing creative automatically.
For most print-on-demand sellers, this one is noise. Waze inventory optimizes toward store visits, store sales, and directions — physical-location goals. If you ship product and have no storefront, it will not touch your account.
Why the channel report is the update that matters for margin
For years the honest critique of PMax was that you could not see inside it. That complaint is now mostly obsolete, and the merchants who win are the ones who read the new report instead of repeating the old line.
Here is why it hits profit. Google's own client data, reported by smec, which manages feeds for hundreds of retailers, shows that between 74% and 97% of PMax cost goes to feed-based Shopping-style ads. The channel report lets you check your own split rather than assume it.
Say you run a store doing 340 orders a month at a $31 average order value, with $2,800 a month flowing through one PMax campaign. You open the channel report and find 78% of that spend went to Search and Shopping surfaces, and 22% went to Display and Gmail. That is $616 a month buying Display impressions.
Now you can ask the real question: did that $616 drive incremental orders, or did it buy cheap clicks that inflated your reported conversions? Before November, portfolio-wide, you were guessing. The report does not answer it automatically, but it gives you the raw split to run the math — which is the whole point of our Google Ads economics guide.
What the November update does not fix
The channel report shows you where ads ran. It does not tell you whether PMax is quietly eating conversions you were already getting for free.
That is the brand-cannibalization problem, and it is still on you to manage. PMax chases the cheapest conversions available, and branded queries are the cheapest of all — so it drifts toward your own brand terms and reports a gorgeous ROAS while adding few truly new orders. Practitioner analyses put the apparent-ROAS inflation from absorbed brand traffic in a meaningful range, as GrowthSpree's breakdown describes.
The fix predates November and still works: account-level brand exclusions plus a dedicated brand Search campaign. We walk through the exact setup in our guide to excluding brand from Performance Max. Pair the new channel report with that exclusion and your "where did the money go" picture gets a lot cleaner.
If you tracked the earlier reporting changes, our rundown of the September 2025 Performance Max updates shows how the transparency features stacked up through the autumn.
How to use the new data to set tROAS
The reason transparency matters is that it feeds a better target. Most merchants set Target ROAS from a number a blog called "good." That is backwards.
Your break-even ROAS is pure arithmetic: 1 ÷ contribution margin. Say you sell a mug for $24 that costs $9 all-in after base cost, shipping share, and fees — that is a $15 margin, so 15 ÷ 24 = 62.5% margin, and 1 ÷ 0.625 = 1.6x break-even. Set tROAS below that and you scale losses; set it far above your account's demonstrated capability and you strangle volume, because the system simply declines auctions it predicts will not clear the bar, which is Google's own documented behavior.
Google's smart bidding needs volume to behave, too. For Search and Shopping, Target ROAS requires at least 15 conversions with values in the trailing 30 days, per the same help page. Below that, expect wobble regardless of how clever your target is.
Say your trailing actual ROAS sits at 3.1x and your break-even is 1.6x. You are already profitable with headroom. The channel report now lets you see whether a target increase would cut the Display spend first (fine) or choke the Search conversions that carry the account (not fine) — a judgment you could not make before this rollout.
And remember the backdrop: costs keep climbing. WordStream's 2025 benchmark data, summarized by Search Engine Land, found roughly 87% of industries saw year-over-year CPC increases. A target set once and forgotten decays as the auction gets more expensive around it.
Where an AI employee fits
Reading the channel report, reconciling conversion value against real orders, and stepping your tROAS by small increments is ongoing work — exactly the kind of grind that gets skipped when you are also sourcing product and answering tickets.
PodVector AI's Victor is an AI employee that operates your Google Ads account alongside Shopify, Meta Ads, Printify, Printful, Gelato, and Klaviyo. Victor computes your true per-order profit — not ROAS, which ignores COGS and fees — so the "is this channel actually paying" question gets a profit answer, not a vanity one. Every write action Victor takes is approval-gated: he proposes the change, you approve before anything executes.
If you want a second set of hands reading the new reports against your real margin, you can try Victor free. And if you would rather hand the whole feed-and-bidding operation to specialists, our take on working with a Google Shopping ads agency lays out the tradeoffs.
FAQs
What are the Performance Max updates from November 2025?
Two shipped on November 6, 2025: channel performance reporting expanded from beta to all advertisers, and Waze "Promoted Places in Navigation" ads joined the inventory for store-goals campaigns, according to Dataslayer. The reporting change matters most for online-only stores; the Waze change is for businesses optimizing toward physical store visits.
Is Performance Max still a black box in 2025?
No, and content that still says so is out of date. Channel reporting, full search-terms reporting, and campaign-level negative keywords all shipped during 2025, as Google's help docs lay out. You can now see which Google surfaces your spend went to and which queries triggered your ads.
Do the Waze ads affect a print-on-demand store?
Usually not. Waze inventory optimizes toward store visits, store sales, and directions, which are physical-location goals. If you ship product with no storefront, it will not enter your account.
What should I actually do with the channel report?
Check your Search-and-Shopping versus Display-and-video split, then reconcile the conversion value PMax reports against your real Shopping orders for the same window. A stable ratio is fine; a sudden gap usually means a tracking break or brand conversions being absorbed. Segment brand versus non-brand before you conclude anything about performance.
Does a high PMax ROAS mean the campaign is working?
Not until brand traffic is excluded or segmented. A PMax campaign eating your branded search can post a spectacular ROAS while adding few incremental orders, a pattern practitioners document widely. Judge PMax on non-brand performance and on total business orders against total ad spend, not on per-campaign ROAS alone.
How should I set my Target ROAS after these updates?
Derive it from break-even math — 1 ÷ your contribution margin — then set the initial target at or slightly below your trailing 30-day actual and step toward your goal. Setting a target far above what the account has achieved suppresses volume rather than creating efficiency, which Google documents directly.
