What is EPC (Earnings Per Click)?

EPC (Earnings Per Click) is average revenue per click on a funnel or offer. In arbitrage, EPC is compared to CPC: if EPC > CPC, the funnel may be profitable before holds and operating costs.

Formula

EPC = Revenue (approved) ÷ Clicks. Example: $800 revenue on 4,000 clicks → EPC = $0.20.

Where it is used

CPA networks publish offer EPC as a guide (often network-wide, not your GEO). Buyers compute their own EPC in the tracker by sub_id, GEO, and creative. Smart links rotate offers by EPC.

EPC vs CR and payout

EPC ≈ CR × payout under fixed CPA and full approval. Falling approval rate lowers EPC without changing tracker CR. Rebills raise EPC over weeks.

Notes

Do not confuse with eCPM (earnings per thousand impressions). EPC on small samples (< 100 clicks) is unstable. Bot clicks in the tracker inflate the denominator and depress EPC.
