Understanding Adsense Jargon
Page Impressions
An “impression” is how many times your web page loads onto a real computer screen. If 30 people looked at your page on their computers, your Page Impression is 30.
Clicks
The actual number of times someone clicks on your ads.
Page CTR
CTR stands for Click Through Rate, a common measurement index for internet-based advertising. CTR is the ratio of people who clicked on your ads to the number who did not, and is calculated using the two set of data:
CTR = (Clicks / Page Impressions) x 100
Page CPM
CPM is used by older internet-based advertising models, in which you pay an advertiser a fixed sum of money for showing 1000 impressions of your ad. The reason why this is included in your Adsense reports is because some advertisers still use the CPM model, and you can compare your Adsense performance with this figure to determine if you are better off showing CPM based ads instead.
Earnings
This tells you how much money you just made today.
