Merchant Center
Review or coordinate Merchant Center setup, product eligibility, feed health and account connections where relevant.
Shopping / PMax architecture
Segment products/categories and campaign responsibility so budget and performance can be understood rather than placing every product into one opaque campaign by default.
Signals and creative
Use available audience/conversion signals and approved assets where they improve the campaign, while recognising that Google controls more of the delivery in automated formats.
Boundary
Large feed remediation, custom feed engineering, marketplace integrations or extensive creative production can require separate scope.
