Google Adsense Definitions

Page Impressions
A page impression is generated every time a user views a page displaying Google ads. We will count one page impression regardless of the number of ads displayed on that page. For example, if you have a page displaying three ad units and it is viewed twice, you will generate two page impressions and six ad unit impressions.

Clicks
In AdSense publisher reports, a click corresponds to a user’s click on any ad on a publisher’s page. The Click column may also include clicks that are deemed to be invalid, and for which no earnings are generated. Clicks on PSAs are not included in publisher reports.

Page 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.

Page eCPM (Cost per thousand impressions)
Cost per 1000 impressions. From a publisher’s perspective, CPM 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. For example, if a publisher earned $180 from 45,000 impressions, the CPM would equal $180/45, or $4.00. However, please keep in mind that eCPM is a reporting feature that does not represent the actual amount paid to a publisher.
