Heard: a key-value targeting fix recovered 6% of house impressions
A lifestyle publisher discovered 6% of impressions were defaulting to house ads.
— A broken key-value pair was excluding inventory from line items
— Demand existed; targeting just never matched
— They rebuilt the kv schema and re-mapped 40 active line items
Those impressions started monetizing again at an avg $1.80 CPM instead of serving zero-revenue house creative.
Impact: Audit your house-ad share. It's often a targeting bug, not low demand.
