Performance Max launched as a deliberately closed box: you gave Google a goal, a budget, and creative assets, and the campaign decided the rest — including which search queries it served for, with almost nothing you could do about the wasteful ones. The 2026 updates change that materially. Google is rolling out a set of new steering and reporting controls for Performance Max that, for the first time, let an account manager actually direct where the money goes at the query level. The headline for anyone focused on search-term hygiene: campaign-level negative keywords are now available to all advertisers, alongside brand controls, customer-list exclusions, and channel-level reporting.
This post is a map of the new control surface rather than another walkthrough of reading the search terms report. The point is to match each 2026 lever to the specific wasted-spend leak it closes, because they do not all solve the same problem — a bad query, brand cannibalisation, and budget draining into a low-intent channel are three different failures with three different fixes. Search Engine Journal confirms the shift, reporting that Google is adding new Performance Max controls and reporting features that hand advertisers more say over query and channel exposure. We will take the levers one at a time and say exactly which leak each one plugs, and where the old visibility limits still bite.
Campaign-level negatives for everyone: the direct query lever
The most consequential 2026 change for search-term hygiene is that campaign-level negative keywords are now available to every Performance Max advertiser, with a ceiling of up to 10,000 per campaign. Previously, adding PMax negatives meant going through a support request or working within tight limits; now it is a self-serve control that holds a real exclusion list. This is the direct lever: you read the queries Performance Max surfaced, find the ones spending without converting, and block them exactly as you would on a Search campaign. If your PMax wasted spend is a query-quality problem — informational searches, free and cheap intent, adjacent product categories you do not sell — this is the control that fixes it.
The catch is that the negative keyword is only as good as the visibility feeding it, and Performance Max still shows less than Search does. It aggregates queries into themes and withholds low-volume terms, so you are building a negative list from a partial view rather than a complete one. The practical response is to treat the terms PMax does surface as representative patterns and block them at the pattern level, not to wait for a full list that never arrives. This is the same discipline the existing Performance Max search terms report and channel negatives workflow describes, now with a self-serve control behind it — and it pairs with the general Performance Max negative keywords mechanics rather than replacing them. The upgrade is access, not visibility: everyone can now negate, but everyone is still negating from a sample.
Brand controls: the branded layer without a hand-built list
Brand controls are the 2026 lever for the branded slice of your traffic, and they solve a problem that negative keywords handle clumsily. Left alone, Performance Max will happily spend on your own brand queries — traffic you can usually capture far more cheaply in a dedicated brand Search campaign — and it can serve for competitor brand terms you would rather never touch. Brand controls let you include or exclude brand terms wholesale in a single setting, rather than trying to enumerate every spelling, spacing, and variation of a brand name as individual negatives. That is the difference: brand controls treat the brand as a concept, where a negative list treats it as a list of strings you have to keep complete by hand.
The reason this matters for wasted-spend work is focus. When brand controls own the branded layer, your negative keyword list can stay pointed at genuine non-brand waste — irrelevant intent, wrong categories, junk modifiers — instead of being cluttered with brand-variation entries that are never quite exhaustive. It is the Performance Max counterpart to the decision covered in Performance Max brand exclusions versus negative keywords: use the purpose-built brand control for the brand question, and reserve negatives for everything else. Decide deliberately whether your brand queries belong in PMax at all — most accounts pull them out so the cheaper brand campaign captures them — and let the brand control enforce that choice cleanly.
Channel-level reporting: diagnosing before you negate
Channel-level reporting is a visibility lever rather than a blocking one, but it belongs in this list because it tells you which fix to reach for. For the first time it shows how your Performance Max budget is distributed across Search, Shopping, Display, YouTube, Discover, Gmail, and Maps — the allocation that was completely hidden before. That distribution is the first thing to read when PMax spend looks wrong, because it separates two problems that a search terms report alone cannot: a query-quality problem, where bad searches on the Search channel are eating budget, versus a channel-mix problem, where the money is draining into low-intent Display or Discover placements that no negative keyword will ever address.
Negative keywords act on queries, so they only help with the first problem. If channel reporting shows most of your spend flowing to Display rather than Search, adding search-term negatives is treating the wrong symptom — the leak is in the channel mix, and you need a different control for it. Reading the channel allocation first turns wasted-spend work from guesswork into diagnosis: you see where the money actually goes, then you pick the lever that reaches that channel. This complements the reporting detail covered in the PMax cross-network field split in reporting, and it is why a 2026 PMax audit starts with channel allocation before it ever gets to the search terms list.
Customer-list exclusions: cutting spend on people you already have
Customer-list exclusions round out the steering suite by letting you keep Performance Max from spending on audiences you specify — most usefully, people already on your customer lists. This is a different kind of wasted spend from a bad search term: the query might be perfectly relevant, but the person searching is an existing customer you did not need to pay to reach again, or a segment you have a reason to exclude from a given campaign's goal. Negative keywords cannot express that, because the waste is about who is searching, not what they typed. Excluding the list is the only clean way to stop it.
For search-term hygiene the takeaway is boundary-drawing: not every unit of wasted PMax spend is a query problem. Some of it is an audience problem, and reaching for a negative keyword to solve an audience issue is the same category error as trying to negate your way out of a channel-mix problem. The 2026 control set is useful precisely because it lets you match the tool to the failure — negatives and brand controls for what people search, channel reporting for where budget flows, customer-list exclusions for who you are paying to reach. Keeping those straight is what stops an audit from firing every lever at every symptom and breaking something that was working.
Putting the levers in order for a 2026 PMax audit
The levers have a natural sequence, and running them in order is what keeps a Performance Max audit from chasing the wrong fix. Start with channel-level reporting to see where the budget actually goes; if the money is pooling in a low-intent channel, that is your first problem and no amount of query hygiene will touch it. Once you have confirmed that Search is carrying the spend you care about, set brand controls so the branded layer is handled deliberately — usually excluded from PMax so a cheaper brand campaign captures it — which clears brand noise out of the search terms view before you start negating. Only then work the search terms report and apply campaign-level negatives to the non-brand waste that remains.
Layer customer-list exclusions wherever the waste is about audience rather than query, and remember through all of it that PMax search-term visibility is still partial, so you are negating from a representative sample and should block at the pattern level rather than term by term. This is the Performance Max chapter of the broader 2026 search hygiene audit playbook, and it rhymes with the division of labour in negatives versus Smart Bidding auto-suppression: each control has a job, and the discipline is using each one only for the leak it is built to close. The 2026 updates finally give Performance Max managers a real steering wheel — the skill now is knowing which way to turn it for the problem in front of you.
