What Performance Max is really doing
Performance Max spreads budget across Google inventory using your assets and goals. It can find efficient conversions. It can also optimise for cheap form fills if that's the only signal you gave it.
When PMax helps
Enough conversion volume
The algorithm needs data to learn. Tiny accounts stay noisy.
Clean goals
Qualified leads or purchases, not vague micro-conversions.
Creative variety
Multiple headlines, images and videos for the system to test.
Proven landing pages
Offer and page already convert in Search or other channels.
When PMax hurts
Weak tracking
You can't tell good leads from tyre-kickers.
You need tight search control
Brand terms and negatives matter more than broad discovery.
Lead quality is undefined
Sales rejects most leads and the machine keeps buying more of them.
Loyalty to a campaign type isn't a strategy. Keep the setups that win on qualified opportunity cost.
How to run it safely
Launch beside a measured Search foundation. Protect brand campaigns. Feed audience signals from CRM lists. Review asset reports and search themes, then pause what dilutes intent.
Agree these kill criteria upfront
Primary metric
Cost per qualified opportunity or booked meeting.
Learning window
A fair period with enough budget before you judge it.
Reallocation rule
If Search wins on the metric, move budget back without drama.
