Metrics
EPCR / EPCV
Earnings per conversion (EPCV) or per click on offer (EPCR).
Variants of EPC. Used inconsistently across networks — always read the network's docs to confirm whether they mean per-click, per-conversion, or per-confirmed-conversion. Most useful for comparing offers on the same network.
Example
Same offer card on MaxBounty shows EPC $1.10 (per outbound click) and EPCV $42 (per confirmed lead). The EPCV is the one that matters for a CPL buyer.
