Revenue per thousand impressions (RPM)
Revenue per 1000 impressions (RPM) represents the estimated earnings that you'd accrue for every 1000 impressions that 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 that you received, then multiplying by 1000.
RPM = (Estimated earnings / Number of page views) * 1000
- 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 programmes, and you may find it helpful for comparing revenue across different channels.
