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.
- If you earned an estimated $180 from 45,000 ad impressions, your ad RPM would equal ($180 / 45,000) * 1000, or $4.00.
RPM is a commonly used number in advertising programs, and you may find it helpful for comparing revenue across different channels.
