Performance Max, with strategic guardrails.
Performance Max is Google's most powerful — and most opaque — campaign type. Hand it your budget without structure and it will spend it. Hand it asset groups, audience signals, and exclusions designed by operators who understand your business, and it can scale dramatically.
PMax is a black box. Most agencies hand it the budget and hope.
Google sells PMax as a one-click solution to performance advertising. The reality is more complex — without proper structure, PMax cannibalises your Search performance, wastes spend on brand searches you would have won anyway, and chases low-quality conversions.
Brand traffic cannibalisation
Without exclusions, PMax will show your brand ads on your own brand searches and claim credit for conversions you'd have won organically. We block this with brand exclusions and proper conversion attribution.
Asset group structure determines everything
PMax assets are grouped, and Google's AI optimizes across the group. Single asset groups hide which themes work. Properly structured asset groups by audience or theme give the AI clear signals.
Audience signals shape the AI
Custom segments, customer match data, and your own first-party audiences tell PMax who to target. Without them, you get generic Google audience modeling that may not fit your business.
Conversion value rules are critical
If you optimize toward gross revenue, PMax will chase low-margin products. If you feed it true margin or LTV-adjusted values, it optimizes toward profit. Most accounts skip this configuration entirely.
Performance Max, finally legible.
PMax will spend whatever you give it. Engineered with signals, exclusions, and strong assets — and read through the data layer, not the platform UI — it scales on incremental revenue instead of recycling your brand demand.
PMax operating system, built from real account learnings.
We've run PMax across 60+ accounts. We know what asset structures work, where the AI fails, and which exclusions matter most.

The black box, watched and steered.
Google hides most of what PMax does. Our agents pull every signal it will surface — search-term insights, asset strength, channel split — then propose the exclusions and assets that steer it toward growth you did not already own.

PMax done right takes structure, not luck.
We treat PMax like any other campaign type — disciplined structure, measurable signals, and continuous optimization. The AI is powerful, but it needs strategic direction.
Strategic foundation
Define the role PMax plays in your account — net-new acquisition, scaling proven products, exploring new audiences. Build asset groups that serve that strategic intent, not generic catch-alls.
Signal architecture
Set up custom audiences from your CRM, customer match lists, value-based conversions, and exclusion rules. The AI is only as good as the signals you feed it.
Iterate and scale
Weekly asset performance reviews, audience signal updates as you gather more data, exclusion list growth based on search term reports. Our AI agents flag asset fatigue and audience saturation before performance degrades.
PMax, run with a steering wheel.
Most agencies hand PMax a budget and call the black box a feature. We treat it as steerable — and prove the growth is incremental.
Quick answers to common questions.
When does PMax actually make sense vs. Standard Shopping or Search?
PMax shines when you have strong conversion data, clear product winners, and want to scale into new audiences. It struggles when you have limited conversion volume, mixed-margin products without value-based bidding, or need fine-grained control. We'll recommend the right campaign type for your specific situation.
Won't PMax just cannibalise our Search and Shopping campaigns?
It will, if you don't set it up properly. With brand exclusions, proper attribution, and clear strategic boundaries between campaign types, PMax adds incremental volume rather than stealing it from existing campaigns. We measure incremental lift, not just last-click attribution.
How is the reporting? PMax is famously opaque.
Reporting in PMax is genuinely worse than Standard campaigns. We pull what data is available — asset group performance, search term insights, audience reports — and combine it with our internal ClickHouse data and tracking pixel for a fuller picture than the Google UI shows.
