How do I read EPC and conversion rate on AI offers?

Two numbers decide almost every optimization choice an affiliate makes: conversion rate and earnings per click. They sound similar, and they often move together, but they answer different questions. Knowing which to trust in which situation is what separates guessing from growing.

• CR = 12 ÷ 800 × 100 = 1.5%
• EPC = $540 ÷ 800 = $0.675

Two sources can have the same conversion rate and very different value, because what each conversion pays varies:

Same CR, but source A is worth 60% more per click. Its visitors come from higher-paying countries or choose yearly plans more often. If you only looked at CR, you would treat them as equal.

EPC is the decision number, but CR is the diagnostic one. When EPC drops, CR tells you why:

• EPC down, CR steady: something changed in what each sale pays, such as more visitors from lower-paying countries or fewer yearly plans.
• EPC down, CR down: fewer visitors are buying, so look at audience fit, the landing page and tracking.
• EPC steady, CR down: you are converting fewer visitors but at higher value per sale. Check whether the change is lasting.

Watching both together turns a vague "earnings are down" into a specific, fixable problem.

Country tier

On CPA, monthly plans pay by the subscriber's country tier. Tier 1 countries pay most, then Tier 2, then Tier 3. A source with more Tier 1 visitors earns more per click at the same CR. See the country lists.

Plan length

The Yearly Infinite plan pays a higher flat rate than monthly plans. Audiences that trust you, such as readers and community members, choose it more often.

Your tier

VIP and PRO pay more per sale than Pink. Moving up raises EPC across all your sources without any change in traffic, as long as your links are on your new tier's offer.

Payout model

On RevShare, EPC grows over time as subscribers renew. A RevShare placement can look weaker than CPA in its first month and stronger after six.

On RevShare, the same clicks keep earning as subscribers renew, so EPC for a period of traffic grows month after month.

These numbers are illustrations, but the shape is real: RevShare EPC keeps climbing while subscribers stay. Compare RevShare and CPA placements over several months, not one.

1. Open the flexible breakdown report.
2. Choose a complete period, such as the last 30 days.
3. Group by Source ID, then by sub-ID.
4. Add columns for clicks, conversions, CR, earnings and EPC.
5. Sort by EPC, highest first.
6. Ignore rows with too few clicks to be meaningful.

Small numbers produce misleading rates. One extra sale can double the CR of a placement with a few hundred clicks.

Also compare complete periods. The last few days always look weaker, because recent sales may still be pending or not yet recorded.

Sugarlab AI and SpiceStars AI reach different audiences, so compare them on the same placement rather than across your whole account. If a community converts well for SpiceStars AI and poorly for Sugarlab AI, that isn't a problem with either app. It is your audience telling you what it wants, and EPC lets you see it clearly.

1. Open your saved breakdown view for the last complete 30 days.
2. Note your three highest-EPC placements and your three lowest.
3. Check whether the lowest ones have enough data to judge.
4. Choose one action: scale a winner, fix a loser or test something new.
5. Write the action down with the date, so you can measure it next week.

For paid traffic, EPC sets the most you can pay per click and still break even:

• If your EPC is $0.60, paying $0.50 per click is profitable and $0.70 loses money.
• For CPM buys, multiply EPC by your click-through rate and by 1,000 to get the break-even CPM.

Compare EPC by country and device, and bid separately where they differ. The traffic buying guide covers this in detail.

When CR is low but traffic fits, the page or the path is usually the problem. Test one change at a time:

• A different landing page that matches the placement's promise.
• A shorter, faster bridge page.
• Clearer, more honest copy before the click.

Give each version its own sub-ID and compare CR, then confirm the winner on EPC. The conversion rate guide has a full testing process.

The Discord post has the best EPC but few clicks, so the affiliate turns it into a weekly event to get more eyes on it. The verdict box is strong and steady, so they add a similar box to two other reviews. The sidebar banner brings the most clicks but the least value, so they swap its creative and check again in a month before deciding whether to remove it.

• Comparing sources on clicks or CR alone.
• Judging a placement after one or two sales.
• Mixing different time periods or time zones.
• Forgetting that pending sales aren't yet in approved earnings.
• Ignoring country and plan mix when EPC changes.

Should I count pending sales in EPC? For a quick view, yes. For decisions about money, especially paid traffic, use approved earnings.

Why is my EPC different from another affiliate's? Different audiences, countries, plans, tiers and placements. Compare your sources with each other, not with someone else.

What is a good EPC? There is no universal answer. A good EPC is one that beats your other placements, and for paid traffic, one that beats your cost per click with room to spare.

Do clicks from the same person count twice? Repeat clicks can be counted, which slightly lowers CR and EPC on placements where people click many times before buying. Compare similar placements with each other to keep it fair.

Is a high CR always good? Not if it comes from low-paying countries or if many of those sales are later refunded. Always check EPC and rejections.

Contact support if your reports show conversions with payouts that don't match the published rates for your tier, country and plan. Include the conversion details and the period.

Two numbers, one habit: check them every week, act on one finding, and your earnings per visitor will keep climbing.
