CPA Network - A CPA network is like a middleman between companies who want to pay based on specific actions and people who promote and earn money from those actions.

CPA Offer - A CPA offer is an advertising offer that pays based on the actions of a potential client, like signing up for something, downloading an app, completing a survey or buying something. It's different from other offers that only pay based on clicks or views.

CPC - CPC or Cost per Click is a way of pricing online ads. It's more reliable than CPM and helps you estimate how many clicks you'll get for your budget.

CPM - Cost per Mille (CPM) is a way of pricing online advertisements. The term "Mille" comes from Latin and means 1000 impressions. So, with CPM, you pay for every 1000 times your ad is seen, instead of paying for each click on the ad.

CPI - CPI, or Cost per Installation, is a way for people to make money by getting paid for every time someone downloads an app. However, it's important to remember that the user has to actually install the app and use it for the person to get paid. If someone just clicks on a link but doesn't actually download and use the app, they won't get paid.

EPC - EPC, or earnings per click, is a really important number when it comes to measuring how well a campaign is doing. It's especially useful for CPA marketing. Basically, EPC tells you how much money you make for each click you get on your campaign. It's a way to see if your campaign is successful or not.
