How does CPM work?

Please help explain

[IanCube]

I'm confused on how the CPM works in relation to revenue.

For example, one day I had the following stats.

Ad Impressions: 11,507
Clicks: 14
CTR%: .01%
CPM: $0.73
Revenue: $8.40

Okay now when I take impressions, divided by 1000, and multiply it times our CPM, I get our total revenue for that day (11.507 x .73 = 8.40).

Now what I'm confused on is, am I supposed to earn anything from the 14 clicks I had, or does YPN only pay based on impressions? I thought it was a conbination of both, or just clicks, but then I look at these numbers, and it just doesn't add up so I'm confused.

Also, does anyone notice a huge difference in revenue from weekends to weekdays?

Thanks,

Ian

CPM is calculated by the total impressions divided by the revenue you made.

AKA Cost Per Thousand (M being the roman symbal for 1000).

The revenue you get is from actual clicks; hence PPC (pay per click) being the type of program YPN is.
