Programmatic yield optimization for Google Ad Manager (GAM). Use this skill whenever the user wants to optimize floor prices, calculate Unified Pricing Rules (UPR), analyze bid landscape data, maximize inventory yield, or improve eCPM/fill-rate trade-offs. Trigger on phrases like "optimize floor", "UPR recommendation", "bid density analysis", "floor price strategy", "maximize yield", "GAM floor", "programmatic revenue", or any request combining fill rate and CPM data. Always use this skill when inventory performance data (avg_cpm, fill_rate, bid range) is provided alongside a request for pricing guidance.
