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've 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
Examples:
- 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, then your ad RPM would equal (£180/45,000) * 1000 or £4.00.
RPM is a commonly used number in advertising programs. You may find it helpful for comparing revenue across different channels.
