Performance Max – PMax for short – has been the most-discussed campaign type in Google Ads since its launch: maximum reach across all Google channels, steered by Google's AI. For a long time, PMax was a black box. Advertisers saw results, but barely where and how their budget was spent. With the 2026 updates, exactly that is changing.
In 2026, Google rolled out a whole wave of new reporting, steering and AI features. The result: significantly more transparency, noticeably more control – and new levers to turn PMax from an opaque automation into a steerable performance machine. We summarize the most important changes and what they mean for your campaigns.
1. Performance Max 2026: From Black-Box Tool to Steerable Campaign
Performance Max bundles all Google ad surfaces – Search, Shopping, YouTube, Display, Discover, Gmail and Maps – into a single, fully automated campaign. You provide assets, goals (conversions or conversion value) and budget; Google's AI does the rest. That is efficient, but for a long time came with one decisive drawback: a lack of transparency and barely any steering options.
This is exactly where the 2026 updates come in. Google is gradually giving advertisers back what many sorely missed: insight into where the budget flows – and concrete levers to steer the AI in the right direction. PMax stays automated, but finally becomes traceable.
In short: 2026 is the year Performance Max shifts from "trust the AI" to "steer the AI with data". Those who consistently use the new reporting and control features get more efficiency out of the same budget.
2. The Most Important Updates at a Glance
The overview below shows how far Performance Max has opened up compared to its early versions – from an opaque automation toward a transparent, steerable campaign type.

3. Channel-Level Reporting: Where Your Budget Really Goes
The single most important update in 2026 is channel-level reporting. For the first time, you can see which Google channels PMax spends your budget on and which channel delivers which results. Instead of one single, opaque total, you now see the distribution across Search, Shopping, YouTube, Display, Discover, Gmail and Maps.
3.1 The channel timeline
A new timeline graph in the campaign reporting shows how each channel contributed to impressions, clicks and conversions over a selected period. Filters let you switch between an investment and a performance view – so you can spot at a glance where budget flows and where it actually drives results. Efficiency gaps become visible before they get expensive.
3.2 "Where ads showed" & video transparency
The "Where ads showed" report provides network-segmented data and makes placements more traceable. In addition, Google improved video transparency: advertisers can now see much more clearly how video assets within PMax contribute to conversions and engagement – an area that was largely in the dark before.
4. More Control: Negative Keywords & Exclusions
Beyond more visibility, Google is also handing over considerably more control in 2026. The most important steering features:
- Campaign-level negative keywords: Can now be added directly and without going through Google support. The limit was raised from 100 to up to 10,000 negative keywords per campaign – ideal for excluding irrelevant search queries and brand traffic.
- Brand exclusions: Deliberately exclude specific brand searches so PMax doesn't waste budget on traffic you'd win anyway.
- Account-level placement exclusions: Prevent delivery on unwanted websites, apps or YouTube channels – now centrally controllable.
- First-party audience exclusions: Exclude your own customer lists so your budget focuses on new-customer acquisition rather than re-engaging existing customers.
Note: more control does not mean "exclude as much as possible". Overly aggressive exclusions constrain the AI and can hurt performance. Apply exclusions based on data – using the new channel and search-term reports – rather than gut feeling.
5. Budget Report & Asset-Group Reporting
A new budget report directly within Performance Max helps you project end-of-month spend and understand how adjusting your daily budget affects performance. This makes budget planning more predictable and avoids nasty surprises at month-end billing.
In addition, the expanded asset-group reporting delivers performance data at the level of individual asset groups – broken down by creative theme. This reveals which messages and creatives truly convert, so you can sharpen your asset groups by performance.
6. AI Max & AI-Powered Asset Generation
In parallel with PMax, Google is pushing AI automation further with AI Max for Search campaigns. AI Max bundles three core features: search-term matching (keywordless reach beyond your existing keywords), text customization (AI-optimized ad copy from existing ads and landing pages) and final URL expansion (more relevant landing pages per query).
According to Google, campaigns using the full AI Max feature set see on average around 7% more conversions or conversion value at a similar CPA/ROAS. New is the Gemini-powered AI Brief: it lets you steer the AI in your own words – context about your business, your message and your target audience. Important to know: existing campaigns using Dynamic Search Ads (DSA), automatically created assets (ACA) and the broad-match setting are automatically upgraded to AI Max by the end of September.
Generative AI is also entering Performance Max itself: on request, Google generates variations of your headlines, descriptions and images that are tested alongside your original assets. Approval stays with you, and AI-generated content is flagged in reporting. In addition, asset experiments are coming to PMax, letting you test creative variations cleanly against each other.
7. New Inventory & Creative Updates
Google is also expanding the ad surfaces: for store-goal campaigns, Waze inventory is added to Performance Max. Businesses appear there as a "Promoted Places in Navigation" pin on the map – relevant for local providers that want to win foot traffic and in-store visits.
On the creative side, Google Ads Editor 2.12 raises the maximum number of videos per asset group to 15. This lets you run video assets more broadly and – thanks to the new video transparency – evaluate them more cleanly.
8. What the Updates Mean for Your Campaigns
Taken together, the updates shift the advertiser's role: away from passive observing, toward data-driven steering. Three practical consequences:
8.1 Optimization becomes possible again – on a data basis
With channel reporting, search-term and asset-group data, PMax can be fine-tuned in a well-founded way for the first time: steer budget toward performing channels, swap out weak creatives, exclude irrelevant queries. Those who don't use this data leave efficiency on the table. In our AI Performance Marketing, we make exactly these levers usable systematically.
8.2 Guide the AI deliberately instead of trusting blindly
AI Max, AI Brief and AI asset generation are powerful – but only as good as the context you provide. Clear target audiences, clean conversion data and well-considered exclusions determine success. We also explore how the advertising world is changing through AI in our article Google AI Update: The New Generation of Ads.
8.3 First-party data becomes a competitive advantage
With audience and customer-list exclusions, the quality of your own data becomes a direct performance lever: those who cleanly separate new-customer acquisition from existing customers get more out of every euro. In parallel, the way users search is changing – more on that in our article on SGE & AI Overviews.

10. Conclusion: More Control, More Responsibility
The Performance Max updates of 2026 send a clear signal: Google is opening the black box. Channel reporting, negative keywords, exclusions and budget transparency finally give advertisers the tools to steer the AI deliberately – instead of trusting it blindly.
But with the control gained comes greater responsibility: the accounts that now consistently evaluate the new data and fine-tune cleanly will outperform those that keep treating PMax as a set-and-forget tool. The advantage doesn't come from the features alone – it comes from their disciplined use.
Our take: in 2026, Performance Max separates the wheat from the chaff. Those who combine reporting, exclusions and AI steering turn the automated reach tool into a precise performance machine. This is exactly where the lever for sustainably better Google Ads results lies.
