CPM (Cost Per Impression) ad networks pays publishers per thousand impressions. It means you will get paid whether your visitors clicks on ad or not. You will earn when the ad gets 1000 impressions.
CPM rates may differ depending upon advertiser, traffic country, niche etc. Its best to use CPM ad network if your blog/website generating large amount of page views per day.
Your Earning = (Number of Impressions / 1000) x CPM Rate
Lets say, if you get 20000 page views per day and you are getting only $1 CPM Rate (Lets take a lowest number) then you can earn 20000/1000 = $20 per day which is not bad at all. Off-course you will get more CPM rate than in the example.
