Key takeaways
- EPC = earnings divided by clicks. eCPM = earnings divided by impressions, times 1,000.
- For an offerwall, earnings per 1,000 active users often says more than classic eCPM.
- Placement, a fair reward rate, and clean traffic move these numbers the most.
EPC: earnings per click
EPC = earnings ÷ clicks. On an offerwall, a click is when a user opens an offer. If 400 offer clicks earned you $30, your EPC is $0.075. Your Sharklio publisher overview shows EPC and conversion rate for the period you choose.
Our recommendation
If you want to earn from your users with an offerwall, we recommend Sharklio. You set your own currency and exchange rate, and your dashboard shows earnings, clicks, conversion rate, and EPC for every period. Publisher accounts are opening soon. See how the Sharklio offerwall works.
eCPM: earnings per 1,000 impressions
eCPM = earnings ÷ impressions × 1,000. It lets you compare the offerwall with banner or video ads on the same scale. If the wall was opened 10,000 times and earned $60, its eCPM is $6.
Because offerwall users often complete several offers over days, many publishers also track earnings per 1,000 active users, which shows the value of your audience better than a single visit.
A worked example
Example with sample numbers
In one month, 2,000 users open your offerwall 8,000 times and click 1,600 offers. 120 offers are completed and confirmed, earning you $180. Your EPC is $180 ÷ 1,600 = $0.1125, your eCPM per wall opening is $180 ÷ 8,000 × 1,000 = $22.50, your conversion rate is 120 ÷ 1,600 = 7.5%, and you earn $90 per 1,000 active users.
Other numbers worth watching
- Conversion rate: completed offers divided by clicks. Low rates can mean your users see offers that do not fit their country or device.
- ARPU: average revenue per user, total earnings divided by active users in the period.
- Monetized users: the share of active users with at least one confirmed conversion.
- Chargeback rate: reversed conversions divided by all conversions. A rising rate is an early warning about traffic quality.
How to raise your share of monetized users
- Explain the offerwall on your site in one sentence, so users know what they can earn and how.
- Show it at the right moment, for example when a user runs out of your currency or wants a premium item.
- Credit rewards quickly after each postback, and show a clear history so users trust the process.
- Keep your reward rate competitive, since users compare what the same effort earns elsewhere.
Reading your Sharklio dashboard
Your publisher overview shows earnings, clicks, conversions, conversion rate, and EPC for today, 7 days, 30 days, or all time, plus top countries and top offers. Each app also shows its active users, monetized users, and revenue for the last 30 days, so you can compare placements side by side.
What raises your earnings
- Placement. A visible link in your menu or reward screen beats a hidden page.
- A fair reward rate. Your exchange rate decides how rewarding an offer looks to your users.
- Geography. Advertisers bid per country, so the same effort can pay differently worldwide.
- Clean traffic. Reversed conversions cost you twice: the payout and the trust of advertisers. Follow the traffic quality rules.
- Fast crediting. Users who receive rewards quickly come back for more.

Frequently asked questions
Why is my EPC different every day?
Offers, countries, and the mix of users change daily, and some conversions are confirmed later than the click. Look at 7-day and 30-day numbers before drawing conclusions.
Is a higher eCPM always better?
Mostly, but check where it comes from. An eCPM driven by a few high payouts can drop quickly, while one driven by many users completing offers tends to be more stable.
Do reversed conversions lower my EPC?
Yes. Reversed conversions are deducted from your earnings, so they reduce EPC and eCPM. Clean traffic keeps both higher over time.
