EPC (Earnings Per Click)

EPC stands for earnings per click. It's the total commission an affiliate has earned divided by the total clicks they sent. EPC = (commissions ÷ clicks). Networks usually report a 7-day or 30-day EPC for each program, often shown as 'EPC $1.42' meaning the average affiliate earns $1.42 for every click they send. EPC is the great equaliser for comparing affiliate programs: a 50% commission on a $10 product sounds great, but if it only converts 1% of the time, the EPC is just $0.05. A 10% commission on a $500 product at the same conversion rate has an EPC of $0.50 — 10× more revenue per click. Smart affiliates optimise for EPC, not commission rate.

EPC is the only metric that ties commission rate, product price and conversion rate together. It tells you exactly how much each click is worth, so you can make rational decisions about which programs to promote, where to put your best traffic and what to A/B test. Improving EPC from $0.20 to $0.40 doubles your revenue from the same traffic — no extra audience required.

1. 1Pick a date range (most networks use 7 or 30 days).
2. 2Sum all approved commissions in that window.
3. 3Divide by the total clicks sent in that window.
4. 4Compare EPC across programs in the same niche.
5. 5Optimise pages and placements to lift EPC over time.

• Move top-EPC offers above the fold on every page.
• Replace generic CTAs with outcome-driven copy.
• Add comparison tables and 'best for' callouts.
• Update old posts with current pricing and offers.
• Cut programs with EPC below your niche baseline.
• Send the right traffic — search intent beats social impressions.

• 100 clicks → $42 commissions = $0.42 EPC.
• Program A: $0.18 EPC. Program B: $0.65 EPC. → switch primary placement to Program B.
• Adding a comparison table to a review post lifts EPC from $0.30 to $0.85.
• SaaS recurring program with a $1.20 first-month EPC and a $4.50 lifetime EPC.

• Comparing EPC across niches — only compare inside the same vertical.
• Looking at clicks alone instead of EPC — high-traffic links can underperform.
• Forgetting that EPC drops if you send unqualified traffic.
• Not factoring in reversals (returns, refunds) when calculating real EPC.
