See POAS vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.
Attributed vs blended contribution by source
- Paid search (attr.)34%
- Paid social (attr.)21%
- Organic / direct30%
- Email / retention15%
MER blends all of these; POAS isolates the paid slices so you can bid on their real profit.
Track POAS automatically from your store — upload profit conversions and scale winners with A/C/X labels.
Different scopes
MER looks at the whole business: all revenue over all marketing spend. It is immune to platform attribution squabbles but blind to margin.
POAS zooms into ad-attributed orders and measures profit. It is the metric you actually bid on.
Reading the traffic mix
A pie of attributed vs blended contribution across sources reveals how much of your revenue depends on paid vs organic and branded demand.
If paid drives most attributed revenue but MER is weak, you are likely renting growth — improve POAS to make that growth profitable.
