Metrics
EPCs (offer card)
Network-published average EPC per offer card.
EPCs published by networks (CB Gravity, MaxBounty offer EPC) are averages across all publishers — heavily skewed by top performers. Don't size a campaign off them. Use them as relative ranking only.
Example
ClickBank Gravity 280 means 280 affiliates earned at least one commission on the offer in the last 8 weeks. High Gravity tells you the offer converts; it does not tell you it will convert for you.
