Performance Max 2026: New Controls, More Reporting — and 45% of all Google Ads Conversions
Performance Max now drives 45% of all Google Ads conversions — and Google is responding with the wave of steering and reporting features advertisers have asked for since the 2022 launch. The 2026 updates close many of the gaps that PMax critics rightly flagged: too little transparency, too little control, too much “trust the algorithm”. Even so, the campaign type stays a black box with a brighter interior, not a Search account in the classical sense.
What changed in concrete terms
- First-party audience exclusions — exclude existing customers from PMax so budget goes to new-customer acquisition.
- Search themes per asset group: 50 instead of 25 — doubling the limit was one of the most-requested changes.
- Asset-level performance ratings plus channel breakdown per asset group.
- Search Terms report for search-driven clicks and placement reports for Display and YouTube.
- Campaign-level negative keywords, brand exclusions, and account-level placement exclusions.
- Video slots per asset group: 15 instead of 5.
- Budget report with end-of-month projection and simulation of daily-budget changes.
- Adoption: 71% of surveyed advertisers run PMax (2025) — up from 60% in 2024.
What used to apply
PMax launched in 2022 as “one campaign for all inventory” — Search, Display, YouTube, Discover, Gmail, Maps, all in a single asset group, with minimal steering. The first years drew sharp criticism from agencies: no transparency on which channel produced what; no real campaign-level negative keywords; brand traffic that bled in unwanted and inflated performance artificially. By 2025 Google had addressed individual pain points (account-level brand exclusions, rudimentary search-terms insights), but the overall picture stayed: Performance Max optimizes, advertiser trusts.
What applies now
1. More steering, without giving up the black-box character First-party audience exclusions are the most important piece. Anyone with a clean Customer Match list of existing customers can now stop PMax from burning budget on re-engagement that would have happened organically or via CRM anyway. Combined with existing brand exclusions, this is the first realistic “PMax for new-customer acquisition” setup. Doubling search themes to 50 per asset group means in practice: thematically broad campaigns no longer need to be split at the asset-group level just to fit the limit.
2. Reporting that finally answers “where does the money go?” Asset-level performance ratings, channel breakdown per asset group, search terms reports, and placement reports — that’s the reporting suite PMax should have had on day one. An important caveat: the search terms report covers only the search-driven share, not Display or YouTube search terms (which don’t really exist in that sense). Placement reports finally provide aggregated lists for the notorious YouTube MFA channels (Made-for-Advertising) that historically ran unnoticed.
3. Budget control with prediction The new budget report projects end-of-month spend at current pacing and simulates how daily-budget changes would affect performance. Combined with Demand-led Budget Pacing — see the Journey-Aware Bidding news — account managers get a halfway reliable view of what will actually land by month end.
Context
The 45% number needs careful reading. It does not say PMax performs 45% better than other campaign types. It says: 45% of measured conversions in the Google Ads universe run through PMax — partly because many advertisers have moved their entire Shopping and Display activity into PMax, since Google has actively pushed that path through its recommendations. That’s market share through default recommendation, not necessarily through isolated superiority.
The new controls are a meaningful step but don’t solve the underlying issue: PMax still decides on its own about channel mix and auction. What Google opens up are levers at the edges — exclude audiences, add themes, keep brand traffic out. The engine room stays sealed.
For accounts with a clear profit-first strategy and a solid first-party-data foundation, the updates are a real improvement. For accounts without CRM integration and without brand/non-brand separation, little changes in practice — the tools are there, but they need to be fed with data from outside.
What you can do now
If you run PMax and have a Customer Match list: activate first-party audience exclusions for existing customers. Measure CPA and new-customer share before and after — not just total conversions.
If you’ve been hitting the search-themes limit: consolidate asset groups that you only split because of the 25 cap, and use the new 50 themes per group.
If your PMax reporting only ever returned conversion totals: pull asset-level performance ratings, channel breakdown, and the search terms report into your standard reporting. Anyone not building this into the weekly review keeps paying PMax blind.
If you want to separate brand and non-brand performance: combine campaign-level brand exclusions with account-level negative keywords. A dedicated brand-search campaign alongside PMax remains the cleaner approach.
