Does anyone have a WAG on their rev per impression ?
Revenue per thousand impressions (RPM) Revenue per 1000 impressions (RPM) represents the estimated earnings you'd accrue for every 1000 impressions you receive. RPM doesn't represent how much you have actually earned; rather, it's calculated by dividing your estimated earnings by the number of page views, impressions, or queries you received, then multiplying by 1000.
Formula: RPM = (Estimated earnings / Number of page views) * 1000
For example:
If you earned an estimated $0.15 from 25 page views, then your page RPM would equal ($0.15 / 25) * 1000, or $6.00."
