Performance Max in 2026: What's Changed and What Works

Performance Max launched as Google's bet on full AI-powered advertising. The pitch was simple: give Google your assets, budget, and goals, and its machine learning would find the best customers across every Google channel. The reality in 2024 was more nuanced — PMax produced results for some advertisers but frustrated others with its opacity, brand cannibalization, and inconsistent performance.

By early 2026, Performance Max is a materially different product. Google has addressed many of the original complaints while doubling down on the automation-first vision. Whether PMax works for you now depends less on the product itself and more on how you configure it, what assets you provide, and how you structure it alongside your Search campaigns.

What Changed in 2025-2026

The most significant changes address the transparency and control gaps that made PMax frustrating for hands-on advertisers. Google did not make PMax a transparent campaign type — you still cannot see individual search terms or control placement-level bids — but they have added enough visibility to make informed optimization possible.

Brand exclusions are now standard

The biggest practical change: you can now exclude your brand terms from PMax at the campaign level without needing Google support. This single feature addresses the number-one complaint about PMax — that it inflated its performance by bidding on branded searches that your Search campaigns would have captured anyway. Apply brand exclusions to every PMax campaign on day one.

Search themes give partial keyword control

Search themes allow you to suggest keyword-level guidance to PMax. While they are not the same as Search campaign keywords (you cannot set match types or see individual term performance), they steer PMax's search inventory toward your priority topics. Think of them as strong hints rather than hard controls.

Improved asset group reporting

PMax now provides more granular reporting at the asset group level, including channel breakdown (Search vs. Display vs. YouTube vs. Discovery), asset performance ratings, and audience segment insights. This data is still less detailed than Search campaign reporting, but it is sufficient for meaningful optimization decisions.
