When to Use

Scenario	Action

Optimizing mid-funnel performance	High costs may indicate targeting users who abandon before entering payment details
Benchmarking campaign quality	Track changes over time to measure campaign optimization effectiveness
Diagnosing checkout drop-off	Compare against cost per initiate checkout to isolate where spend efficiency degrades

Metric	Relationship
Cost per Initiate Checkout	Earlier funnel step — compare to identify where efficiency drops
Cost per Purchase	Later funnel step — tracks cost to complete the transaction
Cost per Add to Cart	Earlier engagement step — measures top-of-funnel efficiency
