GOOGLE AD MANAGER 360 • WATERFALL & UPR SIMULATOR
Priority Tiers 1–16 • Price Floor Rules • Dynamic Allocation
Google Ad Manager 360 Waterfall & Orchestration Simulator
Test how GAM 360 evaluates line item priority hierarchies, reservation guarantees, Unified Price Rules (UPR), and competing Header Bidding / Open Bidding demand to determine auction winners and diagnose delivery conflicts.
Production Boundary Note: Production GAM utilizes real-time Value CPM and pacing algorithms. This simulator is an illustrative model of the decision hierarchy between guaranteed reservation and non-guaranteed programmatic demand.
Interview Context: "Why doesn't the highest CPM always win in an ad server?" • Use this simulation to demonstrate Priority 4 reservation commitments vs. Dynamic Allocation Value CPM pacing.
1. DEMAND: Prebid Adapters & Direct Line Items
→
2. RULES: UPR Floors & Timeout Filters
→
3. AUCTION: 7-Stage Dynamic Allocation Engine
→
4. OUTPUT: Winning Demand & Clearing Log
Interactive Simulation — Not a Live Auction
Header Bidding vs. GAM Dynamic Allocation Visualizer
Modeled client-side auction demonstrating how Prebid.js adapter latencies and bid CPMs translate into targeting key-values (hb_pb, hb_bidder), competing against Google Ad Manager Price Priority (P12) and Google AdX Dynamic Allocation.
