MCM child-seat economics are tightening

Watching: under Multiple Customer Management, manage-account child publishers are seeing parent networks adjust the rev-share split on Google demand without a renegotiation — the change shows up as a quiet drop in your 'Ad Exchange' revenue line, not a contract email.
— Reconcile your AdX payout against impressions monthly, not quarterly
— A widening gap between delivered and paid = check your MCM parent terms
Impact: child publishers absorb splits they never agreed to. Confidence: sourced.
