What is the difference between CPC and EPC?

CPC is the most effective pricing model for smaller advertisers looking to buy guaranteed traffic for their websites. EPC is a different kind of metric that is actually limited to the world of online affiliate marketing.
CPC allows evaluating the efficiency of an advertising campaign, namely figuring out the conversion rate and adjusting bids.
The abbreviation stands for Earnings Per Click, that is, an indicator of the average income per click. This indicator is very important for working with CPA-networks, as it allows you to find out the level of income. Earnings Per Click are calculated by a special formula: EPC = Earnings / Clicks.
