CPM means cost per 1,000 impressions and is a rate. An impression is someone clicking on an advertiser's ad. The advertiser will pay the CPM rate amount for every 1,000 times the ad is clicked on.
At the the 'Ad Program Summary' you will see three things:
34 impressions or clicks. That is all impressions on all of your articles
$6.82 CPM rate at an average of all ads
$0.23 is the earnings
This is how it is figured.
Take the CPM rate ÷ 1,0000 for how much one impression is worth.
$6.82 ÷ 1,000 = $0.00682
Now, multiply that times 34 impressions to get the earnings paid
$0.00682 x 34 = $0.23
The CPM rate will change from day to day. Below the summary is the day to day list. It is figured out the same way and then totaled for the Summary.
