Does a brand Search campaign cannibalize my Performance Max campaign?
The short answer
A brand Search campaign only steals from Performance Max if you let PMax bid on your brand name too. Add your brand terms as negatives in PMax and each one keeps its own lane. Brand clicks are cheap, so you want them in Search. ZenoX runs brand Search next to PMax from day one, with those brand negatives in from the start.
What people are actually seeing
Performance Max reaches across every Google surface, and that includes searches for your own brand name. So when you add a brand Search campaign, PMax often looks like it drops. It did not really drop. The same sales just moved to the campaign that was always going to win them cheapest.
The overlap is real. The fix is one setting, not a strategy change.
The fix: brand terms as PMax negatives
Put your brand terms in as negatives on the Performance Max campaign. Then PMax stops paying for people who already typed your name, and your brand Search campaign catches them instead. Each campaign keeps its own job: PMax finds new buyers, brand Search closes the ones who already know you.
ZenoX adds brand negatives from the start on every account we run, not after somebody notices the overlap in a report. Performance Max still picks up odd search terms even with negatives in, so we read the search terms report twice a week and keep topping the list up.
Why you want brand clicks in Search anyway
Nobody competes hard for your own brand name, so those clicks cost almost nothing. A brand Search campaign is a small spend with a very high return.
And if you do not run one, the slot does not sit empty. A competitor or a comparison site can show up above you when someone searches your own name. That is the real risk, and it is a much bigger one than the overlap people worry about.
