If you run Google Ads against a live product feed, this update is less about new toys and more about new visibility. For years the honest complaint about Performance Max was that you couldn't see where your money went. That excuse is now gone.
Below is what shipped, what it means in dollars, and how to read the new report without chasing numbers that don't pay rent.
What actually changed in Performance Max this November
Google confirmed the changes on November 6, 2025, and two of them matter for ecommerce, according to Search Engine Roundtable.
The big one: channel performance reporting moved from a limited beta to all Performance Max campaigns, with manager-account (MCC) support so agencies and multi-store operators can see channel data across accounts, per Dataslayer's November rollout breakdown.
The second: Google added Waze "Promoted Places in Navigation" inventory to Performance Max for store-goals campaigns in the US, reaching more than a hundred and fifty million active drivers, with international markets planned for next year (Dataslayer). If you ship from a warehouse and have no physical storefront, Waze is noise — skip it. The reporting change is the one you should act on.
Channel performance reporting is now in every account
The channel report breaks your PMax spend and results out by seven surfaces: Search, Display, YouTube, Discover, Gmail, Maps, and search partners (Dataslayer). You see impressions, clicks, conversions, conversion value, and cost per channel.
This didn't appear overnight. Google began the rollout earlier in the year, and Search Engine Journal reported it would reach accounts broadly through late 2025 — November is when it finished landing. Historical data is viewable for any date range after June 6, 2025, per Google Ads Help.
To find it: open your Performance Max campaign, go to Insights and reports, then Channel performance.
Waze ads joined the Performance Max inventory
Waze Promoted Places serve automatically from your existing assets for store-goals campaigns, with no separate setup (Dataslayer). For a POD or dropship store with no local footprint, this adds nothing — your campaign optimizes toward online conversions, not store visits. File it under "good to know," not "act today."
What the channel report actually tells you
Here's why this is the update that touches your P&L: most PMax spend for retailers is Shopping-shaped, not the multi-channel spread the pitch implies.
Smec, which manages hundreds of millions in annual spend for retailers, reports that 74 to 97 percent of PMax cost goes to feed-based (Shopping-style) ads (smec). The channel report lets you confirm that for your account instead of guessing.
The first question to answer: what share of your conversions came from Search versus Display and YouTube? If a chunk of spend went to Display or YouTube at a weak return while Search carried the campaign, you now have the evidence to restructure — which you couldn't do when PMax was a sealed box.
This is also why the "PMax replaced Shopping" framing is outdated. Optmyzr's study of 24,702 PMax campaigns found 82 percent of advertisers run PMax alongside Shopping or Search, and split-budget accounts posted the strongest returns (Optmyzr). The current best practice is portfolio construction, which our Performance Max pros-and-cons breakdown walks through in detail.
Why this update matters for your profit, not just your ROAS
The channel report shows you conversion value. It does not show you profit. That gap is where stores quietly lose money.
Say you run a mug store. A mug sells for $32, your Printify base plus fulfillment cost is $14, your shipping share is about $4, and payment processing takes roughly $1.20. Your contribution per order is $32 − $14 − $4 − $1.20 = $12.80, which is a 40% contribution margin.
Your break-even ROAS is simply 1 ÷ 0.40 = 2.5x. Below a 2.5x return, every order loses money no matter how pretty the channel report looks. A common profit buffer is to set your tROAS target above break-even — 2.5x × 1.3 ≈ 3.25x, or a 325% target.
Now the trap the new report exposes. Suppose your PMax campaign reports a 5.0x ROAS and you feel great. But the channel report shows a large share of those conversions came from Search on branded queries — people typing your store name, who were going to buy anyway. Strip those out and your true, incremental return on new customers might sit near break-even. The report finally lets you run that check, and the full economics of break-even and tROAS live in our Google Ads economics guide.
How to read the new report without chasing vanity metrics
A few rules keep the report useful instead of distracting.
Judge channels on conversion value ÷ cost, not clicks. A channel can deliver cheap clicks and few sales. Divide value by cost per channel and compare against your break-even number above.
Don't panic over a soft month. Smart bidding needs volume to behave: Google requires at least 15 conversions in the past 30 days for Target ROAS on Search and Shopping, per Google Ads Help, and practitioners widely cite closer to 30–50 per month per campaign for stability. If you're below that, the data in the channel report is thin by nature.
Benchmark with ranges, not single numbers. LocaliQ's 2025 retail benchmarks put the retail-category search CPC around $4.14 and conversion rate near 4.01% — directional context, not a target. And remember costs keep climbing: WordStream found roughly 87% of industries saw year-over-year CPC increases. Your break-even math decides what you can pay; a benchmark never does.
The brand cannibalization check the report finally lets you run
This is the single most valuable thing the November update unlocks for an operating store.
PMax chases the cheapest conversions, and branded searches are the cheapest of all. Left unchecked, it absorbs conversions that organic, direct, or your brand Search campaign were already winning, inflating its reported ROAS while adding no new orders.
The fix has existed since 2024: account-level brand exclusions for PMax, which cover brand variants and misspellings (AdNabu). What the channel report adds is the diagnosis — you can now see how much of your PMax Search spend is landing on brand terms before you decide to exclude them.
The honest test is business-level: total orders versus total ad spend, not per-campaign ROAS. If PMax's reported return rose while your overall order count stayed flat, you reallocated credit, not demand. For stores that want a managed path through this, our Google Shopping ads agency overview covers when to bring in help.
Where Victor fits
Reading the new channel report, reconciling it against real costs, and acting on it is ongoing work most store owners don't have time for. Victor, the AI employee inside PodVector AI, is a full Google Ads operator — he pauses the channels bleeding spend, shifts budget toward the surfaces that actually return, and adjusts your tROAS targets off your real numbers.
Because Victor also pulls your Shopify orders and your Printify, Printful, and Gelato product costs into one view, he computes the true per-order profit behind every conversion the channel report counts — then delivers the breakdown to your Google Drive. He sees every order, every ad dollar, and every supplier cost together, so he can tell you which Google Ads channel is making money and which one only looks like it is.

FAQs
What is the main Performance Max update from November 2025?
Channel performance reporting left beta and became available in every Performance Max campaign, including manager-account access, as confirmed by Search Engine Roundtable. It shows your spend and results across seven channels. Google also added Waze Promoted Places inventory for US store-goals campaigns.
Where do I find the channel performance report?
Open your Performance Max campaign, click Insights and reports, then Channel performance. Data is available for any date range after June 6, 2025, per Google Ads Help. You'll see impressions, clicks, conversions, conversion value, and cost broken out by Search, Display, YouTube, Discover, Gmail, Maps, and search partners.
Does the Waze ads update matter for my online store?
Probably not. Waze Promoted Places serve for store-goals campaigns aimed at physical visits (Dataslayer). If you fulfill online with no storefront, your PMax optimizes toward online conversions and Waze inventory won't apply to you.
Does the channel report show my profit?
No. It shows conversion value, which is revenue, not profit. You have to subtract product cost, fulfillment, shipping, and fees yourself. On a $32 mug costing $14 to make, with $4 shipping and $1.20 in fees, you keep $12.80 — a 40% margin and a 2.5x break-even ROAS, so a 5.0x reported return can still lose money if the channel mix is mostly branded clicks.
Should I still run Standard Shopping alongside PMax after this update?
For most accounts, yes. Optmyzr's study of 24,702 campaigns found 82 percent of advertisers run both, and split-budget accounts performed best. The new channel report makes the hybrid easier to manage because you can finally see which surface PMax is favoring.
How does the update help with brand cannibalization?
It lets you see how much of your PMax Search spend hits branded queries before deciding to exclude them. Account-level brand exclusions have existed since 2024 (AdNabu); the channel report supplies the evidence to use them well. Judge PMax on non-brand performance and total business orders, not its headline ROAS.
