See POAS vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.
Profit over time: PMax vs standard Shopping
- PMax profit (profit-fed)
- Standard Shopping profit
Fed the same profit signals, PMax's reach can pull ahead — but only when it optimizes margin, not revenue.
Track POAS automatically from your store — upload profit conversions and scale winners with A/C/X labels.
The control vs automation trade-off
Standard Shopping lets you segment and bid precisely. PMax automates across channels but gives less granular control.
Without profit signals, PMax can chase cheap conversions that erode margin. With profit values, it optimizes toward real contribution.
Profit over time
Plotted over weeks, PMax and Shopping often start close on profit, then diverge based on which one is fed better signals.
The winner is usually 'whichever is fed profit data' — not the campaign type itself.
Frequently asked questions
Common questions about this topic — tap to read answers.
Should I run both?
Many stores do — Shopping for control on hero SKUs, PMax for scale — both fed profit values so neither over-scales low margin.
Can PMax bid on profit?
Yes, indirectly, by feeding profit-weighted conversions. That is the key to keeping its automation profit-aware.
