CTR (Click Through Rate):-                                           

In AdSense publisher reports, clickthrough rate (CTR) is the number of clicks an ad receives divided by the number of times the ad, ad unit, or page is shown, depending on the type of impressions you’re viewing.

CPA (Cost Per Action):

The cost-per-action (CPA) is the amount an advertiser pays when a user completes a certain action. For example, an airline might pay a certain CPA every time a user clicks on their ad and then purchases a plane ticket.

CPC (Cost Per Click):

The CPC is the amount an advertiser pays each time a user clicks on his/her ad. Google AdWords has a CPC pricing system.

CPM (Cost Per Thousand Impressions):

The CPM is the amount an advertiser pays for every 1000 times a user views his/her ad and an impression is recorded.

ECPM (EffectiveCost Per Thousand Impressions):

 The effective cost-per-thousand impressions (eCPM) is a useful way to compare revenue across different channels and advertising programs. It is calculated by dividing total earnings by the number of impressions in thousands.
