Ad impression - whenever an individual ad is displayed
on your website. Different ad formats have different ad impression
values, for instance, a vertical banner will account for two ad
impressions in your report.
Ad unit impression - every time a user views
an ad unit on a page. For example, a page displaying three ad units
that is viewed twice, you will generate six ad unit impressions
and two page impressions.

an ad receives a click divided by the number of times the ad, ad
unit, or page is displayed ][depending on the type of impressions

pays when a user completes a certain action: registers, subscribes,
