Here are a few important terms to become familiar with:
CPC or Cost Per Click: You are paid money for each click on these type of adverts.
CPM or Cost Per One Thousand Impressions: CPM adverts are usually creative or graphical adverts. You are paid every time an advert is viewed, this is regardless of whether they are clicked or not.
CPA or Cost Per Action: When you display CPA adverts, you only get paid when a person completes an offer or purchases a product from the site in the advert. CPA adverts have specific rules as to what is required in order for you to get paid. Generally the payment from CPA adverts is very high but the amount of conversions or actions you get will be very rare.
