EPC shows how much money you make on average for every click on a tracked link.
People managing affiliate programs or ad networks who track link performance.
01What it is and how it works
EPC is calculated by dividing total earnings from a set of clicks by the number of those clicks. The metric is used in affiliate programs, ad networks, and any system that pays per click. When a visitor lands on a page that contains a tracked link, the system records the click. If the click later results in a sale, subscription, or other payout, the revenue is added to the click’s tally. Over many clicks, the average stabilises and gives you a sense of how valuable each click is for your brand.
EPC is the average money earned each time someone clicks a link that you are measuring.
02What to do about it
1. Pull the latest EPC numbers from your affiliate dashboard or ad platform. 2. Compare EPC across different traffic sources (search, social, email) to spot the most profitable channels. 3. Adjust bids or budgets toward sources with higher EPC. 4. Test new creative or landing‑page variations and watch the EPC shift. 5. Set a weekly review cadence so you can react before a low‑performing campaign drains budget.
03How it is measured or noticed
Most platforms expose EPC as a column in their reporting UI. If you need a custom view, export the raw click and revenue data, then run a simple calculation: EPC = total_revenue / total_clicks. Look for sudden drops in the EPC column – they often signal broken links, low‑quality traffic, or changes in commission rates. A stable or rising EPC indicates that your audience is engaging with offers that convert well.
04Common mistakes
- Assuming a high click volume automatically means high profit – EPC can be low if the traffic is cheap but unqualified.
- Ignoring seasonality – EPC often spikes during holidays and falls in off‑peak periods.
- Mixing revenue from different programs without separating them – you’ll get a misleading average.
- Relying on a single day’s EPC to make budget decisions – use at least a week of data for a reliable signal.
05Limits
EPC does not capture downstream value such as repeat purchases or brand lift, so it should not be the sole KPI for brand health. It also becomes meaningless when the click count is very low; a single high‑value sale can inflate the metric. EPC is often confused with CPM (cost per mille) or CPA (cost per acquisition), but those measure cost to you, not earnings you receive.
06Worked example
"In March our fashion affiliate program recorded 4,200 clicks and $1,260 in commissions. Dividing $1,260 by 4,200 gave an EPC of $0.30. After we switched the banner on the lifestyle blog, clicks rose to 5,100 and commissions to $1,845, pushing EPC to $0.36. The higher EPC told us the new creative attracted more buying intent, so we re‑allocated budget to that placement."
Frequently asked questions
How does EPC differ from CPM?
No, EPC is not the same as CPM; EPC measures earnings per click, while CPM measures cost per thousand impressions. EPC reflects revenue generated by clicks, whereas CPM reflects the price of ad exposure regardless of clicks. They serve different purposes in evaluating campaign performance.
Should I use EPC as my primary KPI for brand health?
It depends; EPC can show immediate revenue per click, but it doesn’t capture downstream value such as repeat purchases or brand lift. Relying solely on EPC may lead you to favor low‑cost clicks that don’t build long‑term equity. Combine EPC with metrics like conversion rate, customer lifetime value, and brand awareness for a fuller picture.
How is EPC calculated on my affiliate platform?
Usually, EPC is calculated by dividing the total earnings generated from a set of clicks by the number of those clicks. The platform sums the revenue attributed to each click and then performs the division, often displaying the result as a column in the reporting UI. Make sure the clicks and earnings are filtered to the same time frame for an accurate figure.
Does EPC still matter when I use multi‑touch attribution?
It still works, but with multi‑touch attribution the EPC you see may only represent the earnings credited to the last click. Earlier interactions that contributed to the conversion might not be reflected in the EPC figure, so the metric can understate true value. Consider supplementing EPC with attribution‑aware metrics if you rely on multi‑touch models.
What problems arise if I rely solely on EPC?
If you rely only on EPC, you may overlook repeat purchases, brand lift, and the quality of traffic. Optimizing for the highest EPC can push you toward cheap clicks that generate little downstream value, potentially hurting long‑term growth. Monitoring additional KPIs helps you avoid over‑optimizing for short‑term earnings.
How long does it take for EPC to reflect changes in my campaign?
EPC typically updates as soon as the platform records a click and its associated revenue, but delayed conversions can cause the figure to stabilize after a few days. If your product has a long purchase cycle, you may see EPC fluctuate before settling. Track the metric over several days to confirm the impact of any changes.

Yes, a drop in EPC often means the new copy is attracting cheaper clicks that generate less revenue. Check whether the click volume increased while the average order value stayed the same, or if the audience quality shifted. Adjust the copy or targeting to restore higher‑value clicks.
Usually, that number is EPC, which shows how much money you earn on average for each click on that link. It’s calculated by dividing total earnings from those clicks by the number of clicks. It helps you compare the profitability of different links at a glance.
First, look for a column named "Earnings Per Click" or simply "EPC" in the reporting settings; many platforms let you add or hide columns. If it’s still missing, check the help docs or contact support to enable the metric. In the meantime, you can calculate it manually by dividing total earnings by total clicks.
