The Google Adsense reports contain some Adsense Terminologies you must understand in order to get better understanding of how Google Adsense works. These Terminologies include: CTR, Impression, eCPM.
The AdSense report visible from the Monetize tab ( in Blogger’s dashboard) or when logged in to www.google.com/adsense contains basic information about how many ads have run on your blog, how many clicks were generated, and how much revenue you have earned. Each term in the report is defined below:
Page impression: A page impression is generated every time a user views a page displaying Google ads. Google counts 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:# The number of times an ad was clicked on in the given reporting period.
Page CTR (Clickthrough Rate): The number of ad clicks divided by the number of impressions for the page of ads that appears when a link unit is clicked. For example, if your Ad Units were displayed 50 times and clicked 10 times, the CTR will be 20% (10/50 * 100 ). The higher your CTR, the more Google will suspect you of “invalid clicking“. Some Adsense experts use to say normal CTR should be around 10% or less.
Page eCPM (Effective Cost Per Thousand Impressions): Essentially, effective CPM represents your estimated earnings for every 1000 impressions that you receive. Effective CPM doesn’t represent how much you have actually earned – rather, it’s calculated by dividing your estimated earnings by the number of page impressions, then multiplying by 1,000. For example, if you earned an estimated $0.15 from 25 page impressions, then your page eCPM would equal ($0.15 / 25) * 1,000, or $6.00. If you earned an estimated $180 from 45,000 ad impressions, your ad eCPM would equal ($180 / 45,000) * 1,000 or $4.00.
CPC (Cost Per Click): is the amount of money that you will earn when an ad unit is clicked. CPC values of each Ad Units vary and are determined by many factors, including publisher’s performance and the publisher’s site quality. But in general, the maximum value possible is 20% of the bid value offered by the advertiser dynamic.
Earnings: Total revenue earned to date.
